[Public Roadmap is here](https://github.com/orgs/mercari/projects/1). # Motivation Imagine a system with a backend of multiple microservices. Instead of the client directly communicating with each microservice, it's more efficient to use a dedicated service (BFF - Backend for Frontend) to aggregate information and send it back to the client. However, as the system grows, determining which team should handle the BFF service becomes unclear. This is where Federated Architecture, like [GraphQL (Apollo) Federation](https://www.apollographql.com/docs/federation/), comes in. With GraphQL Federation, each microservice has its own GraphQL server, and the BFF focuses on aggregating resources. However, integrating a new GraphQL server into a large system is challenging, especially in systems developed with the gRPC protocol. To streamline, we're exploring the idea of automatically generating a BFF using the gRPC protocol with simple custom options. By leveraging existing Protocol Buffers schema for the BFF, we aim to keep using gRPC while drastically reducing maintenance costs. # Why Choose gRPC Federation? ## 1. Reduce the Boilerplate Implementation Required to Create a BFF ### 1.1. Automate Type Conversions for the Same Message Across Different Packages Consider defining a BFF using a proto, assuming the BFF acts as a proxy calling multiple microservices and aggregating results. In this scenario, it's necessary to redefine the same messages to handle microservices responses on the BFF. Without defining these messages on the BFF, the BFF client must be aware of different packages, which is not ideal. Redefining messages on the BFF results in a considerable number of type conversions for the same messages across different packages. Using gRPC Federation removes the need for tedious type conversions. Just define custom options in the proto, and gRPC Federation will automatically handle these conversions. ### 1.2. Optimize gRPC Method Calls When making multiple gRPC method calls, it is crucial to enhance performance by analyzing dependencies between method calls and processing requests in parallel whenever possible. However, identifying dependencies becomes more challenging as the number of method calls increases. gRPC Federation simplifies this process by automatically analyzing dependencies and generating code to optimize request flows. It removes the need for manual consideration. ### 1.3. Simplify Retries and Timeouts on gRPC Method Calls Setting timeouts or retry counts for gRPC method calls in dependent services can be complicated. However, gRPC Federation allows for a declarative approach to implementing retries and timeouts. These are just a few examples of how gRPC Federation simplifies work. By creating a BFF with minimal proto definitions, you can significantly reduce the development cost of BFFs. ## 2. Explicitly Declare Dependencies on Services Using gRPC Federation enables a clear understanding of the services the BFF depends on by reading the proto file. It uncovers a relationship between each microservice and BFF. Furthermore, gRPC Federation offers functionality to extract dependencies as a Go library, enabling the extraction of service dependencies through static analysis of the proto file. This capability proves valuable for various types of analysis and automation. # Features ## 1. Code Generation Assistance Tools gRPC Federation automatically generates a gRPC server by adding custom options to Protocol Buffers. It supports the `protoc-gen-grpc-federation` CLI, accessible through `protoc`. Various other tools are available to assist in code generation: - `protoc-gen-grpc-federation`: protoc's plugin for gRPC Federation - `grpc-federation-linter`: Linter for gRPC Federation - `grpc-federation-language-server`: Language server for gRPC Federation - `grpc-federation-generator`: Standalone code generation tool, which monitors proto changes and interactively generates codes ## 2. CEL Support for Complex Operations gRPC Federation integrates [CEL](https://github.com/google/cel-spec) to enable support for more advanced operations on BFFs. [gRPC Federation CEL API References](./docs/cel.md) ## 3. Extensible System with WebAssembly gRPC Federation features three extension points: 1. Code generation pipeline 2. Complex processes not expressible by Protocol Buffers 3. CEL API We plan to make all three extension points available through WebAssembly in the future. Currently, the code generation pipeline and the CEL API are extensible. ### 3.1 Code Generation Pipeline This feature allows you to run a custom auto-generated process using the results from gRPC Federation. [How to Run Your Own Code Generation Process](./docs/code_generation_plugin.md) ### 3.2 Complex Processes Not Expressible by Protocol Buffers gRPC Federation uses a hybrid system, with logic in Go managing operations that can't be expressed in Protocol Buffers. We plan to add support for WebAssembly in the future. [How to Extend the API with the Go](./docs/references.md#grpcfederationmessagecustom_resolver) ### 3.3 CEL API While gRPC Federation inherently supports various CEL APIs, users can use this functionality to use internal domain logic as a CEL API. [How to Extend the CEL API](./docs/cel_plugin.md) # Installation Currently, there are three ways to use gRPC Federation: 1. Use `buf generate` 2. Use `protoc-gen-grpc-federation` 3. Use `grpc-federation-generator` For detailed information on each method, please refer to [Installation Documentation](./docs/installation.md). # Usage - [`Getting Started`](./docs/getting_started.md) - [`DEMO Application`](./demo/README.md) - [`Examples`](./_examples/) # Documents - [Feature References](./docs/references.md) - [CEL API References](./docs/cel.md) # Contribution Please read the CLA carefully before submitting your contribution to Mercari.

Write plugin definition in ProtocolBuffers The plugin feature allows you to define global functions, methods, and variables. [plugin.proto](./proto/plugin/plugin.proto) ## 2. Run code generator Run `make generate` to generate code by `protoc-gen-grpc-federation`. ## 3. Write plugin code [cmd/plugin/main.go](./cmd/plugin/main.go) is the plugin source. The helper code needed to write the plugin is already generated, so it is used. [The helper is here](./plugin/plugin_grpc_federation.pb.go). In `plugin/plugin_grpc_federation.pb.go`, there is a `RegisterRegexpPlugin` function required for plugin registration and a `RegexpPlugin` interface required for the plugin. The code for the plugin is as follows. ```go package main import ( pluginpb "example/plugin" "regexp" "unsafe" ) var _ pluginpb.RegexpPlugin = new(plugin) type plugin struct{} // For example.regexp.compile function. func (_ *plugin) Example_Regexp_Compile(ctx context.Context, expr string) (*pluginpb.Regexp, error) { re, err := regexp.Compile(expr) if err != nil { return nil, err } return &pluginpb.Regexp{ Ptr: uint32(uintptr(unsafe.Pointer(re))), }, nil } // For example.regexp.Regexp.matchString method. func (_ *plugin) Example_Regexp_Regexp_MatchString(ctx context.Context, re *pluginpb.Regexp, s string) (bool, error) { return (*regexp.Regexp)(unsafe.Pointer(uintptr(re.Ptr))).MatchString(s), nil } func main() { pluginpb.RegisterRegexpPlugin(new(plugin)) } ``` ## 4. Compile a plugin to WebAssembly Run `make build/wasm` to compile to WebAssembly. ( `regexp.wasm` is output ) ## 5. Calculates sha256 value for the WebAssembly file ```console $ sha256sum regexp.wasm 820f86011519c42da0fe9876bc2ca7fbee5df746acf104d9e2b9bba802ddd2b9 regexp.wasm ``` ## 6. Load plugin ( WebAssembly ) file Initialize the gRPC server with the path to the wasm file and the sha256 value of the file. ```go federationServer, err := federation.NewFederationService(federation.FederationServiceConfig{ CELPlugin: &federation.FederationServiceCELPluginConfig{ Regexp: federation.FederationServiceCELPluginWasmConfig{ Path: "regexp.wasm", Sha256: "820f86011519c42da0fe9876bc2ca7fbee5df746acf104d9e2b9bba802ddd2b9", }, }, }) ``` ## 7. Plugin usage You can evaluate the plugin's API in the same way you would evaluate a regular usage (e.g. `by` feature). ```proto message IsMatchResponse { option (grpc.federation.message) = { def { name: "matched" by: "example.regexp.compile($.expr).matchString($.target)" } }; bool result = 1 [(grpc.federation.field).by = "matched"]; } ``` ================================================ FILE: _examples/15_cel_plugin/buf.gen.yaml ================================================ version: v1 managed: enabled: true plugins: - plugin: go out: . opt: paths=source_relative - plugin: go-grpc out: . opt: paths=source_relative - plugin: grpc-federation out: . opt: - paths=source_relative - import_paths=proto ================================================ FILE: _examples/15_cel_plugin/buf.work.yaml ================================================ version: v1 directories: - proto - proto_deps ================================================ FILE: _examples/15_cel_plugin/cmd/plugin/main.go ================================================ package main import ( "context" pluginpb "example/plugin" "fmt" "os" "regexp" "strings" "time" "unsafe" "google.golang.org/grpc/metadata" ) type plugin struct{} func (_ *plugin) Val() string { return "hello grpc-federation plugin" } func (_ *plugin) Example_Regexp_Compile(ctx context.Context, expr string) (*pluginpb.Regexp, error) { md, ok := metadata.FromIncomingContext(ctx) if ok { fmt.Fprintf(os.Stderr, "plugin: got metadata is %+v", md) } re, err := regexp.Compile(expr) if err != nil { return nil, err } return &pluginpb.Regexp{ Ptr: uint32(uintptr(unsafe.Pointer(re))), }, nil } func (_ *plugin) Example_Regexp_Regexp_MatchString(ctx context.Context, re *pluginpb.Regexp, s string) (bool, error) { return (*regexp.Regexp)(unsafe.Pointer(uintptr(re.Ptr))).MatchString(s), nil } func (_ *plugin) Example_Regexp_NewExample(_ context.Context) (*pluginpb.Example, error) { return &pluginpb.Example{}, nil } func (_ *plugin) Example_Regexp_NewExamples(_ context.Context) ([]*pluginpb.Example, error) { return []*pluginpb.Example{{}, {}}, nil } func (_ *plugin) Example_Regexp_FilterExamples(_ context.Context, v []*pluginpb.Example) ([]*pluginpb.Example, error) { return v, nil } func (_ *plugin) Example_Regexp_Example_Concat(_ context.Context, _ *pluginpb.Example, v []string) (string, error) { return strings.Join(v, ""), nil } func (_ *plugin) Example_Regexp_Example_Split(_ context.Context, _ *pluginpb.Example, s string, sep string) ([]string, error) { return strings.Split(s, sep), nil } func (_ *plugin) Example_Regexp_Block(ctx context.Context) (bool, error) { time.Sleep(100 * time.Second) return true, nil } func main() { pluginpb.RegisterRegexpPlugin(&plugin{}) } ================================================ FILE: _examples/15_cel_plugin/federation/federation.pb.go ================================================ // Code generated by protoc-gen-go.

So, this is especially effective in CEL value. ### Goto Definition It supports jumps to the following definition sources. - Imported file name - e.g.) import "path/to/foo.proto" - Type of field definition - e.g.) Foo foo = 1 - gRPC method name - e.g.) def { call { method: "foopkg.FooService/BarMethod" } } - Alias name - e.g.) option (grpc.federation.message).alias = "foopkg.Bar" ### Diagnostics ### Code Completion ## Installation ```console $ go install github.com/mercari/grpc-federation/cmd/grpc-federation-language-server@latest ``` ## Usage ```console Usage: grpc-federation-language-server [OPTIONS] Application Options: --log-file= specify the log file path for debugging -I, --import-path= specify the import path for loading proto file Help Options: -h, --help Show this help message ``` ## Clients The list of extensions or plugins for the IDE. ### Visual Studio Code https://marketplace.visualstudio.com/items?itemName=Mercari.grpc-federation ================================================ FILE: cmd/grpc-federation-language-server/main.go ================================================ package main import ( "context" "fmt" "log" "os" "github.com/jessevdk/go-flags" "github.com/mercari/grpc-federation/lsp/server" ) type option struct { LogFile string `description:"specify the log file path for debugging" long:"log-file"` ImportPaths []string `description:"specify the import path for loading proto file" long:"import-path" short:"I"` } func main() { if err := run(context.Background()); err != nil { log.Fatalf("[grpc-federation-language-server]: %+v", err) } } func parseOpt() ([]string, *option, error) { var opt option parser := flags.NewParser(&opt, flags.Default) args, err := parser.Parse() if err != nil { return nil, nil, err } return args, &opt, nil } func run(ctx context.Context) error { _, opt, err := parseOpt() if err != nil { // output error message to stderr by library return nil } var opts []server.ServerOption if opt.LogFile != "" { logFile, err := os.OpenFile(opt.LogFile, os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0666) if err != nil { return fmt.Errorf("failed to open %s: %w", opt.LogFile, err) } defer logFile.Close() opts = append(opts, server.LogFileOption(logFile)) } if len(opt.ImportPaths) != 0 { opts = append(opts, server.ImportPathsOption(opt.ImportPaths)) } svr := server.New(opts...) svr.Run(ctx) return nil } ================================================ FILE: cmd/grpc-federation-linter/main.go ================================================ package main import ( "context" "fmt" "log" "os" "github.com/jessevdk/go-flags" "github.com/mercari/grpc-federation/source" "github.com/mercari/grpc-federation/validator" ) type option struct { ImportPaths []string `description:"specify the import path for loading proto file" long:"import-path" short:"I"` } const ( exitOK = 0 exitERR = 1 ) func main() { args, opt, err := parseOpt() if err != nil { // output error message to stderr by library os.Exit(exitERR) } if len(args) == 0 { log.Fatal("[grpc-federation-linter]: required file path to validation") } ctx := context.Background() var existsErr bool for _, arg := range args { path := arg f, err := os.ReadFile(path) if err != nil { log.Fatalf("[grpc-federation-linter]: failed to read file %s: %v", path, err) } file, err := source.NewFile(path, f) if err != nil { log.Fatalf("[grpc-federation-linter]: %v", err) } v := validator.New() outs := v.Validate(ctx, file, validator.ImportPathOption(opt.ImportPaths...)) if len(outs) == 0 { continue } fmt.Println(validator.Format(outs)) if validator.ExistsError(outs) { existsErr = true } } if existsErr { os.Exit(exitERR) } os.Exit(exitOK) } func parseOpt() ([]string, *option, error) { var opt option parser := flags.NewParser(&opt, flags.Default) args, err := parser.Parse() if err != nil { return nil, nil, err } return args, &opt, nil } ================================================ FILE: cmd/grpc-federation-mcp-server/assets/docs.md ================================================ # How to use gRPC Federation ## Understanding gRPC Federation First, read https://deepwiki.com/mercari/grpc-federation to understand gRPC Federation. The `grpc/federation/federation.proto` is defined at https://github.com/mercari/grpc-federation/blob/main/proto/grpc/federation/federation.proto. The schema defined in this proto represents the options configurable in gRPC Federation. Detailed explanations of these options can be found at https://github.com/mercari/grpc-federation/blob/main/docs/references.md. When describing gRPC Federation options, implement them based on this information. ## Practices for Describing gRPC Federation Options - If you want to validate or process errors returned from dependent microservices, use the `(grpc.federation.message).def.call.error` option. - Avoid creating messages unrelated to the response structure of the microservice you are building. - If the same value is always returned, use Service Variable. Otherwise, create a message only when the same process is used in multiple places and the process itself is complex. If the process is not complex, even if it is the same process, it is preferable to write the process directly in the existing message. Actively use the alias functionality of messages or enums when simple mapping suffices. - To avoid redundant `grpc.federation.field` option descriptions, actively use the `autobind` feature. - You can associate enum values with strings using `(grpc.federation.enum_value).attr`. Use this feature actively if necessary. - gRPC Federation provides a wide range of standard libraries starting with `grpc.federation.*`. Consider whether these features can be utilized as needed. - When the package is the same, you can omit the package prefix when referencing other messages or enums using `(grpc.federation.message).def.message` or `(grpc.federation.message).def.enum`. Otherwise, always include the package prefix. - The CEL specification is available at https://github.com/google/cel-spec/blob/master/doc/langdef.md. - Additionally, in gRPC Federation, you can use the optional keyword (`?`). Always consider using optional when the existence of the target value cannot be guaranteed during field access or index access (the optional feature is also explained at https://pkg.go.dev/github.com/google/cel-go/cel#hdr-Syntax_Changes-OptionalTypes). - Use `custom_resolver` only as a last resort. Use it only when it is impossible to express something in proto. ## Examples of gRPC Federation To learn more about how to describe gRPC Federation options, refer to the examples at https://github.com/mercari/grpc-federation/tree/main/_examples. Each example includes Go language files (`*_grpc_federation.pb.go`) and test codes generated automatically from the proto descriptions. Read these codes as needed to understand the meaning of the options. ## When Changing gRPC Federation Options When changing gRPC Federation options, always compile the target proto file and repeat the process until it succeeds to verify the correctness of the description. Follow the steps below to compile the proto file: 1. Extract the list of import files from the proto file to be compiled. Use the `get_import_proto_list` tool for extraction. 2. Create the absolute path of the import path required to compile the obtained import file list. Analyze the current repository structure to use the correct information. 3. Repeat steps 1 to 2 for the obtained import paths to create a unique and complete list of import paths required for compilation. 4. Use the `compile_proto` tool with the extracted import path list to compile the target proto file. ================================================ FILE: cmd/grpc-federation-mcp-server/main.go ================================================ package main import ( "context" "embed" "encoding/json" "fmt" "log" "os" "github.com/mark3labs/mcp-go/mcp" "github.com/mark3labs/mcp-go/server" "github.com/mercari/grpc-federation/source" "github.com/mercari/grpc-federation/validator" ) //go:embed assets/* var assets embed.FS func main() { docs, err := assets.ReadFile("assets/docs.md") if err != nil { log.Fatalf("failed to read document: %v", err) } // Create a new MCP server s := server.NewMCPServer( "gRPC Federation MCP Server", "1.0.0", server.WithToolCapabilities(false), server.WithResourceCapabilities(false, false), server.WithRecovery(), server.WithInstructions(string(docs)), ) s.AddTool( mcp.NewTool( "get_import_proto_list", mcp.WithDescription("Returns a list of import proto files used in the specified proto file"), mcp.WithString( "path", mcp.Description("The absolute path to the proto file to be analyzed"), mcp.Required(), ), ), func(ctx context.Context, r mcp.CallToolRequest) (*mcp.CallToolResult, error) { args, ok := r.Params.Arguments.(map[string]any) if !ok { return nil, fmt.Errorf("unexpected argument format: %T", r.Params.Arguments) } path, ok := args["path"].(string) if !ok { return nil, fmt.Errorf("failed to find path parameter from arguments: %v", args) } content, err := os.ReadFile(path) if err != nil { return nil, fmt.Errorf("failed to read file: %w", err) } f, err := source.NewFile(path, content) if err != nil { return nil, err } list, err := json.Marshal(append(f.Imports(), f.ImportsByImportRule()...)) if err != nil { return nil, err } return &mcp.CallToolResult{ Content: []mcp.Content{ mcp.TextContent{ Type: "text", Text: string(list), }, }, }, nil }, ) s.AddTool( mcp.NewTool( "compile_proto", mcp.WithDescription("Compile the proto file using the gRPC Federation option"), mcp.WithString( "path", mcp.Description("The absolute path to the proto file to be analyzed"), mcp.Required(), ), mcp.WithArray( "import_paths", mcp.Description("Specify the list of import paths required to locate dependency files during compilation.

is an example of building a simple service using gRPC Federation with SWAPI. ## What is SWAPI ? [SWAPI](https://swapi.dev/) is one of the public APIs. It frequently appears as an example for GraphQL and gRPC, so we are using it with gRPC Federation as well. ## Background and Architecture The service we are building this time with gRPC Federation is a BFF (Backend for Frontend) that consolidates the results of several pre-existing services ( `film` , `person` , `planet` , `species` , `starship` , `vehicle` ). Please consider these pre-existing services as in-house microservices in a real-world scenario. Each of them is developed and managed by a different team. Each microservice exposes internal APIs using gRPC, with schemas managed by Protocol Buffers. Our goal is to build a gRPC service that aggregates the necessary information from each service and exposes it externally. [![Architecture](./images/arch.png)](./images/arch.png) ## How to use The Protocol Buffers files for each microservice are located under the `./proto` directory. Additionally, we will create the `swapi.proto` file for this project, which is already placed in `./proto/swapi.proto` . The `swapi.proto` file contains the API schema and the gRPC Federation options. The following is an excerpt from it. - swapi.proto ```proto // GetPersonReply message for SWAPI. message GetPersonReply { // gRPC Federation Options. option (grpc.federation.message) = { def { name: "res" call { method: "swapi.person.PersonService/GetPerson" request { field: "id" by: "$.id" } } } ... }; } ``` In this demo, we will use `Buf` to generate code from the proto files utilizing gRPC Federation. First, you need to install the Buf CLI by running the following command: ```console make tools ``` If the installation is successful, the `buf` and `ko` and `grpcurl` binaries will be installed under the `bin` directory. To generate code using Buf, execute the following command: ```console make generate ``` The code will be generated under the `./swapi/swapi` directory. Next, build the server and create the image. In this demo, it's necessary to start other microservices simultaneously, so the code for each is also provided. To build the code for all services and create images, execute the following command: ```console make build ``` Finally, start all services. Use `docker compose` for launching. The SWAPI service will be available on port `3000`. ( See [config file](./compose.yaml) ) ```console make up ``` Now, let's send a request to confirm the functionality. If you receive a response after sending a request like the following, the application is running successfully. ``` ./bin/grpcurl -plaintext -d '{"id": 1}' localhost:3000 swapi.SWAPI/GetPerson ``` Additionally, we are using [JAEGER](https://www.jaegertracing.io/) to visualize OpenTelemetry traces. It is exposed on port `4000`, so please try accessing it in your browser. If you can see a page like the following, it means it's successful. - `http://localhost:4000` [![Jaeger UI](./images/jaeger.png)](./images/jaeger.png) ## Conclusion The team responsible for providing the SWAPI service needs to develop and maintain only the `swapi.proto` file and the `./cmd/swapi/main.go` file. The `swapi.proto` file utilizes gRPC Federation. In the `./cmd/swapi/main.go` file, additional tasks such as defining gRPC clients, which cannot be described solely with gRPC Federation, need to be addressed. Please feel free to edit the `swapi.proto` file and explore the capabilities of gRPC Federation !!! ================================================ FILE: demo/buf.gen.yaml

It is used when performing field binding for enums that map multiple enums with an alias. If you try to return an enum value without using this function, an error will occur due to type mismatch. e.g.) `true ? pkg.EnumType.Enum_VALUE_A : pkgv2.EnumType.ENUM_VALUE_B` ``` grpc-federation: ERROR: :1:6: found no matching overload for '_?_:_' applied to '(bool, pkg.EnumType(int), pkgv2.EnumType(int))' | true ? pkg.EnumType.value('ENUM_VALUE_A') : pkgv2.EnumType.value('ENUM_VALUE_B') | .....^ ``` ### Parameters `select(cond bool, , ) grpc.federation.private.EnumSelector` - `cond`: condition to select enum value - `first-enum-value`: first enum value. this is selected if the condition is true. - `second-enum-value`: second enum value. this is selected if the condition is false. ### Examples ```cel grpc.federation.enum.select(true, pkg.EnumType.ENUM_VALUE_A, pkgv2.EnumType.ENUM_VALUE_B) ``` ## `.name` For all enum types, you can use the `name` method to obtain the name of the enum value as a string. ### Parameters `pkg.EnumType.name() string` - ``: int or enum typed value ### Examples In the following case, `"ENUM_VALUE_1"` ( string typed value) is returned. ```cel foo.EnumType.name(foo.EnumType.ENUM_VALUE_1) ``` ```proto package foo; enum EnumType { ENUM_VALUE_UNKNOWN = 0; ENUM_VALUE_1 = 1; } ``` ## `.value` For all enum types, you can use the `value` method to obtain the enum typed value from name. ### Parameters `pkg.EnumType.value(enumValueName string) EnumValue` - `enumValueName`: name of the enum value - `EnumValue`: enum typed value. This value can be used as an argument for the `select` function ### Examples In the following case, `foo.EnumType.ENUM_VALUE_1` ( enum typed value) is returned. ```cel foo.EnumType.value('ENUM_VALUE_1') ``` ```proto package foo; enum EnumType { ENUM_VALUE_UNKNOWN = 0; ENUM_VALUE_1 = 1; } ``` ## `.from` For all enum types, you can use the `from` method to obtain the enum typed value from int value. ### Parameters `pkg.EnumType.from(enumValue int) EnumValue` - `enumValue`: int typed value of the enum value - `EnumValue`: enum typed value. This value can be used as an argument for the `select` function ### Examples In the following case, `foo.EnumType.ENUM_VALUE_1` ( enum typed value) is returned. > [!NOTE] > Here, you might be confused by the difference between `foo.EnumType.ENUM_VALUE_1` appearing in the expression and the returned `foo.EnumType.ENUM_VALUE_1` value. > As a basic principle, CEL treats enum values as int types when specified directly. > The `from` method is used to convert this to a typed enum value. > Although the result looks the same, it is actually typed and can be used as an argument for the `select` function. ```cel foo.EnumType.from(foo.EnumType.ENUM_VALUE_1) ``` ```proto package foo; enum EnumType { ENUM_VALUE_UNKNOWN = 0; ENUM_VALUE_1 = 1; } ``` ## `.attr` If you use `attr` to hold multiple name-value pairs corresponding to an enum value, you can get value from `name`. ### Parameters `pkg.EnumType.attr(enumValue EnumValue, name string) string` - `enumValue`: the enum value - `name`: string value to search attribute. ### Examples In the following case, `Foo.text` value is `foo`. ```proto package mypkg; message Foo { option (grpc.federation.message) = { def { name: "v" by: "Type.value('VALUE_1')" } }; string text = 1 [(grpc.federation.field).by = "Type.attr(v, 'attr_x')"]; } enum Type { VALUE_1 = 1 [(grpc.federation.enum_value).attr = { name: "attr_x" value: "foo" }]; VALUE_2 = 2 [(grpc.federation.enum_value).attr = { name: "attr_x" value: "bar" }]; } ``` ================================================ FILE: docs/cel/list.md ================================================ # grpc.federation.list APIs # Index - [`reduce`](#reduce) - [`first`](#first) - [`sortAsc`](#sortAsc) - [`sortDesc`](#sortDesc) - [`sortStableAsc`](#sortStableAsc) - [`sortStableDesc`](#sortStableDesc) # Macros ## reduce `reduce` executes a user-supplied "reducer" expression on each element of the repeated type, in order, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements of the repeated type is a single value. ### Parameters `range.reduce(accumulator, current, , )` - `range`: repeated type value - `accumulator` : The value resulting from the previous `` expression. On the first call, its value is the result of `` expression. - `current`: current iteration value - ``: expression for reduce operation - ``: expression for initial value ### Examples ```cel [2, 3, 4].reduce(accum, cur, accum + cur, 1) //=> 10 ``` ## first Returns the element that evaluates to `` when the result is true. If all elements are not matched, `optional.none` is returned. Thus, the return value of `first` will always be of optional type. The optional value can be used as is for field binding. `first` is equivalent to the following expression. ```cel range.filter(var, )[?0] ``` ### Parameters `range.first(var, )` - `range`: repeated type value - `var`: current iteration value - ``: Write a conditional expression to return the first match. Must return a boolean value. ### Examples ```cel [1, 2, 3, 4].first(v, v % 2 == 0) //=> optional.of(2) ``` ## sortAsc Returns elements sorted in ascending order.

The representation limits the largest representable duration to approximately 290 years. `Duration` type is compatible with [`google.protobuf.Duration`](https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/duration.proto) type. FYI: https://pkg.go.dev/time#Duration ## Location A `Location` maps time instants to the zone in use at that time. Typically, the Location represents the collection of time offsets in use in a geographical area. For many Locations the time offset varies depending on whether daylight savings time is in use at the time instant. FYI: https://pkg.go.dev/time#Location ## google.protobuf.Timestamp ## asTime `asTime` converts google.protobuf.Timestamp value to grpc.federation.time.Time value. ### Parameters `asTime() Time` ### Examples ```cel google.protobuf.Timestamp{}.asTime() //=> grpc.federation.time.Time{timestamp: google.protobuf.Timestamp{}} ``` ## Time A `Time` represents `google.protobuf.Timestamp` with time zone. # Constants FYI: https://pkg.go.dev/time#pkg-constants ## LAYOUT ### type `string` ### value `01/02 03:04:05PM '06 -0700` ## ANSIC ### type `string` ### value `Mon Jan _2 15:04:05 2006` ## UNIX_DATE ### type `string` ### value `Mon Jan _2 15:04:05 MST 2006` ## RUBY_DATE ### type `string` ### value `Mon Jan 02 15:04:05 -0700 2006` ## RFC822 ### type `string` ### value `02 Jan 06 15:04 MST` ## RFC822Z ### type `string` ### value `02 Jan 06 15:04 -0700` ## RFC850 ### type `string` ### value `Monday, 02-Jan-06 15:04:05 MST` ## RFC1123 ### type `string` ### value `Mon, 02 Jan 2006 15:04:05 MST` ## RFC1123Z ### type `string` ### value `Mon, 02 Jan 2006 15:04:05 -0700` ## RFC3339 ### type `string` ### value `2006-01-02T15:04:05Z07:00` ## RFC3339NANO ### type `string` ### value `2006-01-02T15:04:05.999999999Z07:00` ## KITCHEN ### type `string` ### value `3:04PM` ## STAMP ### type `string` ### value `Jan _2 15:04:05` ## STAMP_MILLI ### type `string` ### value `Jan _2 15:04:05.000` ## STAMP_MICRO ### type `string` ### value `Jan _2 15:04:05.000000` ## STAMP_NANO ### type `string` ### value `Jan _2 15:04:05.000000000` ## DATETIME ### type `string` ### value `2006-01-02 15:04:05` ## DATE_ONLY ### type `string` ### value `2006-01-02` ## TIME_ONLY ### type `string` ### value `15:04:05` ## NANOSECOND ### type `int` ### value `1` ## MICROSECOND ### type `int` ### value `1000 * grpc.federation.time.NANOSECOND` ## MILLISECOND ### type `int` ### value `1000 * grpc.federation.time.MICROSECOND` ## SECOND ### type `int` ### value `1000 * grpc.federation.time.MILLISECOND` ## MINUTE ### type `int` ### value `60 * grpc.federation.time.SECOND` ## HOUR ### type `int` ### value `60 * grpc.federation.time.MINUTE` # Functions ## toDuration `toDuration` converts int type to `Duration` type. ### Parameters `toDuration(var int) Duration` - `var`: source value ### Examples ```cel grpc.federation.time.toDuration(10 * grpc.federation.time.SECOND) // 10s ``` ## parseDuration `parseDuration` parses a duration string. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". FYI: https://pkg.go.dev/time#ParseDuration ### Parameters `parseDuration(s string) Duration` - `s`: duration string ### Examples ```cel grpc.federation.time.parseDuration("1h10m10s") ``` ## since `since` returns the time elapsed since `t`. It is shorthand for `now().sub(t)`. FYI: https://pkg.go.dev/time#Since ### Parameters `since(t Time) Duration` - `t`: time value ### Examples ```cel grpc.federation.time.since(grpc.federation.time.now()) ``` ## until `until` returns the duration until `t`. It is shorthand for `t.sub(now())`. ### Parameters `until(t Time) Duration` - `t`: time value ### Examples ```cel grpc.federation.time.until(grpc.federation.time.now()) ``` ## Duration.abs `abs` returns the absolute value of `Duration`. As a special case, `` is converted to ``.

The rounding behavior for halfway values is to round away from zero. If the result exceeds the maximum (or minimum) value that can be stored in a Duration, `round` returns the maximum (or minimum) duration. If `m` <= 0, `round` returns `Duration` unchanged. ### Parameters `Duration.round(m Duration) Duration` - `m`: the value for round operation ### Examples ```cel grpc.federation.time.parseDuration("1h15m30.918273645s").round(grpc.federation.time.MILLISECOND) //=> 1h15m30.918s ``` ## Duration.seconds `seconds` returns the duration as a double type number of seconds. FYI: https://pkg.go.dev/time#Duration.Seconds ### Parameters `Duration.seconds() double` ### Examples ```cel grpc.federation.time.parseDuration("1m30s").seconds() //=> 90 ``` ## Duration.string `string` returns a string representing the duration in the form "72h3m0.5s". Leading zero units are omitted. As a special case, durations less than one second format use a smaller unit (milli-, micro-, or nanoseconds) to ensure that the leading digit is non-zero. The zero duration formats as 0s. FYI: https://pkg.go.dev/time#Duration.String ### Parameters `Duration.string() string` ### Examples ```cel grpc.federation.time.toDuration(grpc.federation.time.HOUR + 2*grpc.federatino.time.MINUTE).string() //=> 1h2m ``` ## Duration.truncate `truncate` returns the result of rounding d toward zero to a multiple of `m`. If `m` <= 0, `truncate` returns `Duration` unchanged. FYI: https://pkg.go.dev/time#Duration.Truncate ### Parameters `Duration.truncate(m Duration) Duration` - `m`: the value for truncate operation ### Examples ```cel grpc.federation.time.parseDuration("1h15m30.918273645s").truncate(grpc.federation.time.MILLISECOND) //=> 1h15m30.918s ``` ## LOCAL `LOCAL` represents the system's local time zone. On Unix systems, `LOCAL` consults the TZ environment variable to find the time zone to use. No TZ means use the system default /etc/localtime. TZ="" means use UTC. TZ="foo" means use file foo in the system timezone directory. ### Parameters `LOCAL() Location` ## UTC `UTC` represents Universal Coordinated Time (UTC). ### Parameters `UTC() Location` ## fixedZone `fixedZone` returns a `Location` that always uses the given zone name and offset (seconds east of `UTC`). FYI: https://pkg.go.dev/time#FixedZone ### Parameters `fixedZone(name string, offset int) Location` - `name`: the zone name - `offset`: the seconds east of `UTC` ### Examples ```cel grpc.federation.time.fixedZone("UTC-8", -8*60*60) ``` ## loadLocation `loadLocation` returns the `Location` with the given name. If the name is `""` or `"UTC"`, `loadLocation` returns `UTC`. If the name is `"Local"`, `loadLocation` returns `LOCAL`. Otherwise, the name is taken to be a location name corresponding to a file in the IANA Time Zone database, such as `"America/New_York"`. FYI: https://pkg.go.dev/time#LoadLocation ### Parameters `loadLocation(name string) Location` ### Examples ```cel grpc.federation.time.loadLocation("America/Los_Angeles") ``` ## loadLocationFromTZData `loadLocationFromTZData` returns a `Location` with the given name initialized from the IANA Time Zone database-formatted data. The data should be in the format of a standard IANA time zone file (for example, the content of /etc/localtime on Unix systems). FYI: https://pkg.go.dev/time#LoadLocationFromTZData ### Parameters `loadLocationFromTZData(name string data bytes) Location` - `name`: the zone name - `data`: the IANA Time Zone database-formatted data ## Location.string `string` returns a descriptive name for the time zone information, corresponding to the name argument to `loadLocation` or `fixedZone`.

FYI: https://pkg.go.dev/time#Now ### Parameters `now() Time` ### Examples ```cel grpc.federation.time.now() ``` ## parse `parse` parses a formatted string and returns the time value it represents. See the documentation for the constant called `LAYOUT` to see how to represent the format. The second argument must be parseable using the format string (layout) provided as the first argument. FYI: https://pkg.go.dev/time#Parse ### Parameters `parse(layout string, value string) Time` ### Examples ```cel grpc.federation.time.parse("2006-Jan-02", "2013-Feb-03") ``` ## parseInLocation `parseInLocation` is like `parse` but differs in two important ways. First, in the absence of time zone information, `parse` interprets a time as `UTC`; `parseInLocation` interprets the time as in the given location. Second, when given a zone offset or abbreviation, `parse` tries to match it against the `LOCAL` location; `parseInLocation` uses the given location. FYI: https://pkg.go.dev/time#ParseInLocation ### Parameters `parseInLocation(layout string, value string, loc Location) Time` ### Examples ```cel grpc.federation.time.parseInLocation("Jan 2, 2006 at 3:04pm (MST)", "Jul 9, 2012 at 5:02am (CEST)", grpc.federation.time.loadLocation("Europe/Berlin")) ``` ## unix `unix` returns the local Time corresponding to the given Unix time, sec seconds and nsec nanoseconds since January 1, 1970 UTC. It is valid to pass nsec outside the range [0, 999999999]. Not all sec values have a corresponding time value. One such value is 1<<63-1 (the largest int64 value). FYI: https://pkg.go.dev/time#Unix ### Parameters `unix(sec int, nsec int) Time` - `sec`: the second value - `nsec`: the nanosecond value ## unixMicro `unixMicro` returns the local Time corresponding to the given Unix time, usec microseconds since January 1, 1970 UTC. FYI: https://pkg.go.dev/time#UnixMicro ### Parameters `unixMicro(usec int) Time` - `usec`: microseconds since January 1, 1970 UTC. ## unixMilli `unixMilli` returns the local Time corresponding to the given Unix time, msec milliseconds since January 1, 1970 UTC. FYI: https://pkg.go.dev/time#UnixMilli ### Parameters `unixMilli(msec int) Time` - `msec`: milliseconds since January 1, 1970 UTC. ## Time.add `add` returns the time `Time`+`d`. FYI: https://pkg.go.dev/time#Time.Add ### Parameters `Time.add(d Duration) Time` - `d`: Duration value ## Time.addDate `addDate` returns the time corresponding to adding the given number of years, months, and days to `Time`. For example, `addDate(-1, 2, 3)` applied to January 1, 2011 returns March 4, 2010. `addDate` normalizes its result in the same way that Date does, so, for example, adding one month to October 31 yields December 1, the normalized form for November 31. FYI: https://pkg.go.dev/time#Time.AddDate ### Parameters `Time.addDate(years int, months int, days int) Time` - `years`: year number - `months`: month number - `days`: day number ## Time.after `after` reports whether the time instant `Time` is after `u`. FYI: https://pkg.go.dev/time#Time.After ### Parameters `Time.after(u Time) bool` - `u`: the time value to compare ### Examples ```cel grpc.federation.time.date(3000, 1, 1, 0, 0, 0, 0, grpc.federation.time.UTC()).after(grpc.federation.time.date(2000, 1, 1, 0, 0, 0, 0, grpc.federation.time.UTC())) //=> true ``` ## Time.appendFormat `appendFormat` is like Format but appends the textual representation to `b` and returns the extended buffer. FYI: https://pkg.go.dev/time#Time.AppendFormat ### Parameters - `Time.appendFormat(b bytes, layout string) string` - `Time.appendFormat(s string, layout string) string` ### Examples ```cel grpc.federation.time.date(2017, 11, 4, 11, 0, 0, 0, grpc.federation.time.UTC()).appendFormat("Time: ", grpc.federation.time.KITCHEN) //=> Time: 11:00AM ``` ## Time.before `before` reports whether the time instant `Time` is before `u`. FYI: https://pkg.go.dev/time#Time.Before ### Parameters `Time.before(u Time) bool` - `u`: the time value to compare ### Examples ```cel grpc.federation.time.date(2000, 1, 1, 0, 0, 0, 0, grpc.federation.time.UTC()).before(grpc.federation.time.date(3000, 1, 1, 0, 0, 0, 0, grpc.federation.time.UTC())) //=> true ``` ## Time.compare `compare` compares the time instant `Time` with `u`. If `Time` is before `u`, it returns `-1`; if `Time` is after `u`, it returns `+1`; if they're the same, it returns `0`. FYI: https://pkg.go.dev/time#Time.Compare ### Parameters `Time.compare(u Time) int` - `u`: the time value to compare ## Time.day `day` returns the day of the month specified by `Time`. FYI: https://pkg.go.dev/time#Time.Day ### Parameters `Time.day() int` ### Examples ```cel grpc.federation.time.date(2000, 2, 1, 12, 30, 0, 0, grpc.federation.time.UTC()).day() //=> 1 ``` ## Time.equal `equal` reports whether `Time` and `u` represent the same time instant. Two times can be equal even if they are in different locations. For example, 6:00 +0200 and 4:00 UTC are Equal. See the documentation on the Time type for the pitfalls of using == with Time values; most code should use `equal` instead. FYI: https://pkg.go.dev/time#Time.Equal ### Parameters `Time.equal(u Time) bool` ### Examples ```cel grpc.federation.time.date(2000, 2, 1, 12, 30, 0, 0, grpc.federation.time.UTC()).equal(grpc.federation.time.date(2000, 2, 1, 20, 30, 0, 0, grpc.federation.time.fixedZone('Beijing Time', grpc.federation.time.toDuration(8 * grpc.federation.time.HOUR).seconds()))) //=> true ``` ## Time.format `format` returns a textual representation of the time value formatted according to the layout defined by the argument. See the documentation for the constant called Layout to see how to represent the layout format. FYI: https://pkg.go.dev/time#Time.Format ### Parameters `Time.format(layout string) string` - `layout`: the layout value to format ## Time.hour `hour` returns the hour within the day specified by `Time`, in the range [0, 23]. FYI: https://pkg.go.dev/time#Time.Hour ### Parameters `Time.hour() int` ## Time.withLocation `withLocation` returns a copy of `Time` representing the same time instant, but with the copy's location information set to loc for display purposes. FYI: https://pkg.go.dev/time#Time.In ### Parameters `Time.withLocation(loc Location) Time` ## Time.isDST `isDST` reports whether the time in the configured location is in Daylight Savings Time. FYI: https://pkg.go.dev/time#Time.IsDST ### Parameters `Time.isDST() bool` ## Time.isZero `isZero` reports whether `Time` represents the zero time instant, January 1, year 1, 00:00:00 UTC. FYI: https://pkg.go.dev/time#Time.IsZero ### Parameters `Time.isZero() bool` ## Time.local `local` returns `Time` with the location set to local time. FYI: https://pkg.go.dev/time#Time.Local ### Parameters `Time.local() Time` ## Time.location `location` returns the time zone information associated with `Time`. FYI: https://pkg.go.dev/time#Time.Location ### Parameters `Time.location() Location` ## Time.minute `minute` returns the minute offset within the hour specified by `Time`, in the range [0, 59]. FYI: https://pkg.go.dev/time#Time.Minute ### Parameters `Time.minute() int` ## Time.month `month` returns the month of the year specified by `Time`. FYI: https://pkg.go.dev/time#Time.Month ### Parameters `Time.month() int` ## Time.nanosecond `nanosecond` returns the nanosecond offset within the second specified by `Time`, in the range [0, 999999999]. FYI: https://pkg.go.dev/time#Time.Nanosecond ### Parameters `Time.nanosecond() int` ## Time.round `round` returns the result of rounding `Time` to the nearest multiple of `d` (since the zero time). The rounding behavior for halfway values is to round up. If d <= 0, `round` returns `Time` stripped of any monotonic clock reading but otherwise unchanged. `round` operates on the time as an absolute duration since the zero time; it does not operate on the presentation form of the time. Thus, `round(grpc.federation.time.HOUR)` may return a time with a non-zero minute, depending on the time's Location. FYI: https://pkg.go.dev/time#Time.Round ### Parameters `Time.round(d Duration) Time` - `d`: the duration value ### Examples ```cel grpc.federation.time.date(0, 0, 0, 12, 15, 30, 918273645, grpc.federation.time.UTC()).round(grpc.federation.time.MILLISECOND).format("15:04:05.999999999") //=> 12:15:30.918 ``` ## Time.second `second` returns the second offset within the minute specified by `Time`, in the range [0, 59]. FYI: https://pkg.go.dev/time#Time.Second ### Parameters `Time.second() int` ## Time.string `string` returns the time formatted using the format string. ``` "2006-01-02 15:04:05.999999999 -0700 MST" ``` If the time has a monotonic clock reading, the returned string includes a final field "m=±", where value is the monotonic clock reading formatted as a decimal number of seconds. FYI: https://pkg.go.dev/time#Time.String ### Parameters `Time.string() string` ## Time.sub `sub` returns the duration `Time`-`u`. If the result exceeds the maximum (or minimum) value that can be stored in a Duration, the maximum (or minimum) duration will be returned. To compute `Time`-`d` for a duration `d`, use `Time.add(-d)`. FYI: https://pkg.go.dev/time#Time.Sub ### Parameters `Time.sub(u Time) Duration` - `u`: the time value ### Examples ```cel grpc.federation.time.date(2000, 1, 1, 12, 0, 0, 0, grpc.federation.time.UTC()).sub(grpc.federation.time.date(2000, 1, 1, 0, 0, 0, 0, grpc.federation.time.UTC())) //=> 12h0m0s ``` ## Time.truncate `truncate` returns the result of rounding `Time` down to a multiple of `d` (since the zero time). If `d` <= 0, `truncate` returns `Time` stripped of any monotonic clock reading but otherwise unchanged. `truncate` operates on the time as an absolute duration since the zero time; it does not operate on the presentation form of the time. Thus, `truncate(grpc.federation.time.HOUR)` may return a time with a non-zero minute, depending on the time's Location. FYI: https://pkg.go.dev/time#Time.Truncate ### Parameters `Time.truncate(d Duration) Time` - `d`: since the zero time ### Examples ```cel grpc.federation.time.parse("2006 Jan 02 15:04:05", "2012 Dec 07 12:15:30.918273645").truncate(grpc.federation.time.MILLISECOND).format("15:04:05.999999999") //=> 12:15:30.918 ``` ## Time.utc `utc` returns `Time` with the location set to UTC. FYI: https://pkg.go.dev/time#Time.UTC ### Parameters `Time.utc() Time` ## Time.unix `unix` returns t as a Unix time, the number of seconds elapsed since January 1, 1970 UTC. The result does not depend on the location associated with `Time`. Unix-like operating systems often record time as a 32-bit count of seconds, but since the method here returns a 64-bit value it is valid for billions of years into the past or future. FYI: https://pkg.go.dev/time#Time.Unix ### Parameters `Time.unix() int` ## Time.unixMicro `unixMicro` returns `Time` as a Unix time, the number of microseconds elapsed since January 1, 1970 UTC. The result is undefined if the Unix time in microseconds cannot be represented by an int64 (a date before year -290307 or after year 294246). The result does not depend on the location associated with `Time`. FYI: https://pkg.go.dev/time#Time.UnixMicro ### Parameters `Time.unixMicro() int` ## Time.unixMilli `unixMilli` returns `Time` as a Unix time, the number of milliseconds elapsed since January 1, 1970 UTC. The result is undefined if the Unix time in milliseconds cannot be represented by an int64 (a date more than 292 million years before or after 1970). The result does not depend on the location associated with `Time`. FYI: https://pkg.go.dev/time#Time.UnixMilli ### Parameters `Time.unixMilli() int` ## Time.unixNano `unixNano` returns `Time` as a Unix time, the number of nanoseconds elapsed since January 1, 1970 UTC. The result is undefined if the Unix time in nanoseconds cannot be represented by an int64 (a date before the year 1678 or after 2262). Note that this means the result of calling UnixNano on the zero Time is undefined. The result does not depend on the location associated with `Time`. FYI: https://pkg.go.dev/time#Time.UnixNano ### Parameters `Time.unixNano() int` ## Time.weekday `weekday` returns the day of the week specified by `Time`. FYI: https://pkg.go.dev/time#Time.Weekday ### Parameters `Time.weekday() int` ## Time.year `year` returns the year in which `Time` occurs. FYI: https://pkg.go.dev/time#Time.Year ### Parameters `Time.year() int` ## Time.yearDay `yearDay` returns the day of the year specified by `Time`, in the range [1,365] for non-leap years, and [1,366] in leap years. FYI: https://pkg.go.dev/time#Time.YearDay ### Parameters `Time.yearDay() int` ================================================ FILE: docs/cel/url.md ================================================ # grpc.federation.url APIs The API for this package was created based on Go's [`net/url`](https://pkg.go.dev/net/url) package. # Index ## Functions -

For more information on CEL, [please see here](https://github.com/google/cel-spec/blob/master/doc/langdef.md). [Here is a list of macros that CEL supports by default](https://github.com/google/cel-spec/blob/master/doc/langdef.md#macros). In addition to the standard CEL operations, the gRPC Federation supports a number of its own APIs. This page introduces those APIs. - [grpc.federation.any APIs](./cel/any.md) - [grpc.federation.enum APIs](./cel/enum.md) - [grpc.federation.list APIs](./cel/list.md) - [grpc.federation.log APIs](./cel/log.md) - [grpc.federation.math APIs](./cel/math.md) - [grpc.federation.metadata APIs](./cel/metadata.md) - [grpc.federation.rand APIs](./cel/rand.md) - [grpc.federation.regexp APIs](./cel/regexp.md) - [grpc.federation.time APIs](./cel/time.md) - [grpc.federation.uuid APIs](./cel/uuid.md) ## Refer to the defined variable If you have defined variables using [`def`](#grpcfederationmessagedef) feature, you can use them in CEL. Also, the message argument should be `$.` can be used to refer to them. ## error `error` is a reserved word. The `error` variable is used to represent errors in gRPC method calls. [The type of the `error` variable is defined here](../proto/grpc/federation/private.proto). ### Example ```proto if: "error.precondition_failures[0].violations[0].subject == 'subject value'" ``` ### Type Definition | field | type | | ----- | ---- | | `code` | int32 | | `message` | string | | `details` | repeated google.protobuf.Any | | `custom_messages` | repeated google.protobuf.Any | | `error_info` | repeated google.rpc.ErrorInfo | | `retry_info` | repeated google.rpc.RetryInfo | | `debug_info` | repeated google.rpc.DebugInfo | | `quota_failures` | repeated google.rpc.QuotaFailure | | `precondition_failures` | repeated google.rpc.PreconditionFailure | | `bad_requests` | repeated google.rpc.BadRequest | | `request_info` | repeated google.rpc.RequestInfo | | `resource_info` | repeated google.rpc.ResourceInfo | | `helps` | repeated google.rpc.Help | | `localized_messages` | repeated google.rpc.LocalizedMessage | ================================================ FILE: docs/cel_plugin.md ================================================ # How to extend the CEL API This document explains how you can add your own logic as a CEL API and make it available to the gRPC Federation. We call this mechanism the CEL Plugin. This document is based on [_examples/15_cel_plugin](./../_examples/15_cel_plugin/). If you would like to see a working sample, please refer to that document. ## 1. Write API definitions in ProtocolBuffers First, define in ProtocolBuffers the types, functions you want to provide. ```proto syntax = "proto3"; package example.regexp; import "grpc/federation/federation.proto"; option go_package = "example/plugin;pluginpb"; message Regexp { uint64 ptr = 1; // store raw pointer value. } option (grpc.federation.file).plugin.export = { name: "regexp" types: [ { name: "Regexp" methods: [ { name: "matchString" args { type { kind: STRING } } return { kind: BOOL } } ] } ] functions: [ { name: "compile" args { type { kind: STRING } } return { message: "Regexp" } } ] }; ``` `(grpc.federation.file).plugin.export` option is used to define the API. In this example, the plugin is named `regexp`. The `regexp` plugin belongs to the `example.regexp` package. Also, this provides the `Regexp` message type and makes `matchString` available as a method on the `Regexp` message, and `compile` function is also added. In summary, it contains the following definitions. - `example.regexp.Regexp` message - `example.regexp.Regexp.matchString(string) bool` method - `example.regexp.compile(string) example.regexp.Regexp` function Put this definition in `plugin/plugin.proto` . ## 2. Use the defined CEL API in your BFF Next, write the code to use the defined API. The following definition is a sample of adding a gRPC method that compiles the `expr` specified by the `example.regexp.compile` function and returns whether the contents of `target` matches the result. ```proto syntax = "proto3"; package org.federation; import "grpc/federation/federation.proto"; import "plugin/plugin.proto"; // your CEL API definition option go_package = "example/federation;federation"; service FederationService { option (grpc.federation.service) = {}; rpc IsMatch(IsMatchRequest) returns (IsMatchResponse) {}; } message IsMatchRequest { string expr = 1; string target = 2; } message IsMatchResponse { option (grpc.federation.message) = { def { name: "matched" // Use the defined CEL API. by: "example.regexp.compile($.expr).matchString($.target)" } }; bool result = 1 [(grpc.federation.field).by = "matched"]; } ``` ## 3. Run code generator Run the gRPC Federation code generator to generate Go language code. At this time, CEL API's schema is verified by the gRPC Federation Compiler, and an error is output if it is used incorrectly. ## 4. Write CEL Plugin code By the code generation, the library code is generated to write the plugin. In this example, the output is in `plugin/plugin_grpc_federation.pb.go`. Using that library, write a plugin as follows. ```go package main import ( pluginpb "example/plugin" "regexp" "unsafe" ) var _ pluginpb.RegexpPlugin = new(plugin) type plugin struct{} // For example.regexp.compile function. func (_ *plugin) Example_Regexp_Compile(ctx context.Context, expr string) (*pluginpb.Regexp, error) { re, err := regexp.Compile(expr) if err != nil { return nil, err } return &pluginpb.Regexp{ Ptr: uint32(uintptr(unsafe.Pointer(re))), }, nil } // For example.regexp.Regexp.matchString method. func (_ *plugin) Example_Regexp_Regexp_MatchString(ctx context.Context, re *pluginpb.Regexp, s string) (bool, error) { return (*regexp.Regexp)(unsafe.Pointer(uintptr(re.Ptr))).MatchString(s), nil } func main() { pluginpb.RegisterRegexpPlugin(new(plugin)) } ``` `pluginpb.RegisterRegexpPlugin` function for registering developed plugins. Also, `pluginpb.RegexpPlugin` is interface type for plugin. ## 5. Compile plugin to WebAssembly ```console $ GOOS=wasip1 GOARCH=wasm go build -o regexp.wasm ./cmd/plugin ``` ## 6. Calculates sha256 value for the WebAssembly file ```console $ sha256sum regexp.wasm 820f86011519c42da0fe9876bc2ca7fbee5df746acf104d9e2b9bba802ddd2b9 regexp.wasm ``` ## 7. Load plugin ( WebAssembly ) file Initialize the gRPC server with the path to the wasm file and the sha256 value of the file. ```go federationServer, err := federation.NewFederationService(federation.FederationServiceConfig{ CELPlugin: &federation.FederationServiceCELPluginConfig{ Regexp: federation.FederationServiceCELPluginWasmConfig{ Path: "regexp.wasm", Sha256: "820f86011519c42da0fe9876bc2ca7fbee5df746acf104d9e2b9bba802ddd2b9", }, }, }) ``` ## Resource Capability By default, plugins do not have access to Environment variables, File System, or Network. This helps to run plugins securely, but there may be cases where you want to allow access to these resources. In such cases, you can enable access to each resource by configuring as follows: ```proto option (grpc.federation.file).plugin.export = { name: "regexp" capability { network: {} // enable network access via HTTP/HTTPS env { names: ["foo"] } // enable access to `FOO` environment variable file_system { mount_path: "/" } // enable access to file system from mount point `/` } } ``` For more details, please refer to the sample that uses this configuration in [_examples/21_wasm_net](../_examples/21_wasm_net/). ### Env If the prefix is `GRPC_FEDERATION_PLUGIN_` , the environment variable will be set for the plugin with that prefix removed. If an environment variable with the same name is already set, it will be overwritten. Since setting `GOMAXPROCS` to 2 or higher causes a panic, it is always set to 1. For example, if you want to turn off GC for the plugin only, set it like this: `GRPC_FEDERATION_PLUGIN_GOGC=off` At the same time, you need to allow all environment variables via capability, or allow them using a whitelist format. ```proto option (grpc.federation.file).plugin.export = { name: "example" capability { env { names: ["gogc"] } // enable access to `GOGC` environment variable } } ``` or ```proto option (grpc.federation.file).plugin.export = { name: "example" capability { env { all: true } // enable all environment variable } } ``` # How it works Host and wasm plugin using stdio to exchange data. The exchanged data types are `CELPluginRequest` and `CELPluginResponse` defined on [plugin.proto](https://github.com/mercari/grpc-federation/blob/main/proto/grpc/federation/plugin.proto). Actually, the data is converted to json and then exchanged. ================================================ FILE: docs/code_generation_plugin.md ================================================ # How to run your own code generation process gRPC Federation supports code generation plugin system for running your own code generation process. This document is based on [_examples/16_code_gen_plugin](./../_examples/16_code_gen_plugin/). If you would like to see a working sample, please refer it. ## 1. Write code generation process ```go package main import ( _ "embed" "fmt" "log" "os" "github.com/mercari/grpc-federation/grpc/federation/generator" ) //go:embed resolver.go.tmpl var tmpl []byte func main() { req, err := generator.ToCodeGeneratorRequest(os.Stdin) if err != nil { log.Fatal(err) } for _, file := range req.GRPCFederationFiles { for _, svc := range file.Services { fmt.Println("service name", svc.Name) for _, method := range svc.Methods { fmt.Println("method name", method.Name) if method.Rule != nil { fmt.Println("method timeout", method.Rule.Timeout) } } } for _, msg := range file.Messages { fmt.Println("msg name", msg.Name) } } if err := os.WriteFile("resolver_test.go", tmpl, 0o600); err != nil { log.Fatal(err) } } ``` You can use `embed` library as you would normally write a Go program. Also, since `os.Stdin` is the value of encode [generator.proto](../proto/grpc/federation/generator.proto), you can use `generator.ToCodeGeneratorRequest` API to decode it. `generator.CodeGeneratorRequest` contains information from the gRPC Federation's analyzing results of the proto file. Therefore, it can be used to implement code generation process you want. > [!NOTE] > The relative path is the directory where the code generation was performed. ## 2. Compile plugin to WebAssembly ```console $ GOOS=wasip1 GOARCH=wasm go build -o plugin.wasm ./cmd/plugin ``` ## 3. Calculates sha256 value for the WebAssembly file ```console $ sha256sum plugin.wasm d010eb2cb5ad1c95d428bfea50dcce918619f4760230588e8c3df95635c992fe plugin.wasm ``` ## 4. Add `plugins` option If you are using `Buf`, add an option in the format `plugins=:` to the `grpc-federation` plugin option. - ``: `http://`, `https://`, `file://` schemes are supported. - `http://` and `https://`: Download and use the specified wasm file. - `file://`: Refer to a file on the local file system. If you start with `/`, the path expected an absolute path. - ``: The content hash of the wasm file. It is used for validation of the wasm file. - buf.gen.yaml ```yaml version: v1 managed: enabled: true plugins: - plugin: go out: . opt: paths=source_relative - plugin: go-grpc out: . opt: paths=source_relative - plugin: grpc-federation out: . opt: - paths=source_relative - plugins=file://plugin.wasm:d010eb2cb5ad1c95d428bfea50dcce918619f4760230588e8c3df95635c992fe ``` If you use `grpc-federation.yaml` for code generation, please describe it in the same way. - grpc-federation.yaml ```yaml imports: - proto src: - proto out: . plugins: - plugin: go opt: paths=source_relative - plugin: go-grpc opt: paths=source_relative - plugin: grpc-federation opt: - paths=source_relative - plugins=file://plugin.wasm:d010eb2cb5ad1c95d428bfea50dcce918619f4760230588e8c3df95635c992fe ``` ## 5. Run code generator Run the gRPC Federation code generator. ```console buf generate ``` or ```console grpc-federation-generator ./proto/federation/federation.proto ``` ## 6. Run your code generator The plugin is executed and the `resover_test.go` file is created in the current working directory. ================================================ FILE: docs/getting_started.md ================================================ # Getting Started Consider the example of creating a BFF ( `FederationService` ) that combines and returns the results obtained using the `PostService` and `UserService`. This example’s architecture is following. ![arch](https://github.com/mercari/grpc-federation/assets/209884/dbd4a32d-5f63-49eb-b32b-36600c09968e) 1. End-User sends a gRPC request to `FederationService` with `post id` 2. `FederationService` sends a gRPC request to `PostService` microservice with `post id` to get `Post` message 3. `FederationService` sends a gRPC request to `UserService` microservice with the `user_id` present in the `Post` message and retrieves the `User` message 4. `FederationService` aggregates `Post` and `User` messages and returns it to the End-User as a single message The Protocol Buffers file definitions of `PostService` and `UserService` and `FederationService` are as follows. ## PostService `PostService` has `GetPost` gRPC method. It returns `Post` message. - post.proto ```proto package post; service PostService { rpc GetPost (GetPostRequest) returns (GetPostReply) {} } message GetPostRequest { string post_id = 1; } message GetPostReply { Post post = 1; } message Post { string id = 1; string title = 2; string content = 3; string user_id = 4; } ``` ## UserService `UserService` has `GetUser` gRPC method. It returns `User` message. - user.proto ```proto package user; service UserService { rpc GetUser (GetUserRequest) returns (GetUserReply) {} } message GetUserRequest { string user_id = 1; } message GetUserReply { User user = 1; } message User { string id = 1; string name = 2; int64 age = 3; } ``` ## FederationService `FederationService` has a `GetPost` method that aggregates the `Post` and `User` messages retrieved from `PostService` and `UserService` and returns it as a single message. - federation.proto ```proto package federation; service FederationService { rpc GetPost (GetPostRequest) returns (GetPostReply) {} } message GetPostRequest { string id = 1; } message GetPostReply { Post post = 1; } message Post { string id = 1; string title = 2; string content = 3; User user = 4; } message User { string id = 1; string name = 2; int64 age = 3; } ``` ## 1. Add `grpc.federation.service` option `grpc.federation.service` option is used to specify a service to generated target using gRPC Federation. Therefore, your first step is to import the gRPC Federation proto file and add the service option. ```diff +import "grpc/federation/federation.proto"; service FederationService { + option (grpc.federation.service) = {}; rpc GetPost (GetPostRequest) returns (GetPostReply) {} } ``` ## 2. Add `grpc.federation.message` option to the response message gRPC Federation focuses on the response message of the gRPC method. Therefore, add an option to the `GetPostReply` message, which is the response message of the `GetPost` method, to describe how to construct the response message. - federation.proto ```diff message GetPostReply { + option (grpc.federation.message) = {}; Post post = 1; } ``` ## 3. Use `def` feature of `grpc.federation.message` option In the gRPC Federation, `grpc.federation.message` option creates a variable and `grpc.federation.field` option refers to that variable and assigns a value to the field. So first, we use [`def`](https://github.com/mercari/grpc-federation/blob/main/docs/references.md#grpcfederationmessagedef) to define variables. - federation.proto ```diff message GetPostReply { option (grpc.federation.message) = { + def { + name: "p" + message { + name: "Post" + args { name: "pid", by: "$.id" } + } + } }; Post post = 1; } ``` The above definition is equivalent to the following pseudo Go code. ```go // getGetPostReply returns GetPostReply message by GetPostRequest message. func getGetPostReply(req *pb.GetPostRequest) *pb.GetPostReply { p := getPost(&PostArgument{Pid: req.GetId()}) ... } // getPost returns Post message by PostArgument. func getPost(arg *PostArgument) *pb.Post { postID := arg.Pid ... } ``` - `name: "p"`: It means to create a variable named `p` - `message {}`: It means to get message instance - `name: "Post"`: It means to get `Post` message in `federation` package. - `args: {name: "pid", by: "$.id"}`: It means to retrieve the Post message, to pass as an argument a value whose name is `pid` and whose value is `$.id`. `$.id` indicates a reference to a message argument. The message argument for a `GetPostReply` message is a `GetPostRequest` message. Therefore, the `"$."` can be used to refer to each field of `GetPostRequest` message. For more information on each feature, please refer to the [API Reference](./references.md) ## 4. Add `grpc.federation.field` option to the response message Assigns the value using `grpc.federation.field` option to a field ( field binding ). `p` variable type is a `Post` message type and `Post post = 1` field also `Post` message type. Therefore, it can be assigned as is without type conversion. ```diff message GetPostReply { option (grpc.federation.message) = { def { name: "p" message { name: "Post" args { name: "pid", by: "$.id" } } } }; + Post post = 1 [(grpc.federation.field).by = "p"]; } ``` ## 5. Add `grpc.federation.message` option to the Post message To create `GetPostReply` message, `Post` message is required. Therefore, it is necessary to define how to create `Post` message, by adding an gRPC Federation's option to `Post` message as in `GetPostReply` message. ```proto message GetPostReply { option (grpc.federation.message) = { def { name: "p" message { name: "Post" args { name: "pid", by: "$.id" } } } }; Post post = 1 [(grpc.federation.field).by = "p"]; } message Post { option (grpc.federation.message) = { // call post.PostService/GetPost method with post_id and binds the response message to `res` variable def { name: "res" call { method: "post.PostService/GetPost" request { field: "post_id", by: "$.pid" } } } // refer to `res` variable and access post field. // Use autobind feature with the retrieved value. def { by: "res.post" autobind: true } }; string id = 1; // binds the value of `res.post.id` by autobind feature string title = 2; // binds the value of `res.post.title` by autobind feature string content = 3; // binds the value of `res.post.content` by autobind feature User user = 4; // TODO } ``` In `def`, besides getting the message, you can call the gRPC method and assign the result to a variable, or get another value from the value of a variable and assign it to a new variable. The first `def` in the `Post` message calls `post.PostService`'s `GetPost` method and assigns the result to the `res` variable. The second `def` in the `Post` message access `post` field of `res` variable and use `autobind` feature for easy field binding. > [!TIP] > [`autobind`](https://github.com/mercari/grpc-federation/blob/main/docs/references.md#grpcfederationmessagedefautobind) > > If the defined value is a message type and the field of that message type exists in the message with the same name and type, the field binding is automatically performed. If multiple autobinds are used at the same message, you must explicitly use the grpc.federation.field option to do the binding yourself, since duplicate field names cannot be correctly determined as one. ## 6. Add gRPC Federation option to the User message Finally, since `Post` message depends on `User` message, add an option to `User` message. ```proto message Post { option (grpc.federation.message) = { def { name: "res" call { method: "post.PostService/GetPost" request { field: "post_id", by: "$.pid" } } } def { // the value of `res.post` assigns to `post` variable. name: "post" by: "res.post" autobind: true } // get User message and assign it to `u` variable. // The `post` variable is referenced to retrieve the `user_id`, and the value is named `uid` as an argument for User message. def { name: "u" message { name: "User" args { name: "uid", by: "post.user_id" } } } }; string id = 1; string title = 2; string content = 3; // binds `u` variable to user field. User user = 4 [(grpc.federation.field).by = "u"]; } message User { option (grpc.federation.message) = { def [ { name: "res" call { method: "user.UserService/GetUser" // refer to message arguments with `$.uid` request { field: "user_id", by: "$.uid" } } }, { by: "res.user" autobind: true } ] }; string id = 1; string name = 3; int age = 3; } ``` ## 7. Run code generator The final completed proto definition will look like this. - federation.proto ```proto package federation; import "grpc/federation/federation.proto"; import "post.proto"; import "user.proto"; service FederationService { option (grpc.federation.service) = {}; rpc GetPost (GetPostRequest) returns (GetPostReply) {} } message GetPostRequest { string id = 1; } message GetPostReply { option (grpc.federation.message) = { def { name: "p" message { name: "Post" args { name: "pid", by: "$.id" } } } }; Post post = 1 [(grpc.federation.field).by = "p"]; } message Post { option (grpc.federation.message) = { def { name: "res" call { method: "post.PostService/GetPost" request { field: "post_id", by: "$.pid" } } } def { name: "post" by: "res.post" autobind: true } def { name: "u" message { name: "User" args { name: "uid", by: "post.user_id" } } } }; string id = 1; string title = 2; string content = 3; User user = 4 [(grpc.federation.field).by = "u"]; } message User { option (grpc.federation.message) = { def [ { name: "res" call { method: "user.UserService/GetUser" request { field: "user_id", by: "$.uid" } } }, { by: "res.user" autobind: true } ] }; string id = 1; string name = 3; int age = 3; } ``` Next, generates gRPC server codes using by this `federation.proto`. First, install `grpc-federation-generator` ```console go install github.com/mercari/grpc-federation/cmd/grpc-federation-generator@latest ``` Puts `federation.proto`, `post.proto`, `user.proto` files to under the `proto` directory. Also, write `grpc-federation.yaml` file to run generator. - grpc-federation.yaml ```yaml imports: - proto src: - proto out: . ``` Run code generator by the following command. ```console grpc-federation-generator ./proto/federation.proto ``` ## 8. Use generated server Running code generation using the `federation.proto` will create a `federation_grpc_federation.pb.go` file under the output path. In `federation_grpc_federation.pb.go`, an initialization function ( `NewFederationService` ) for the `FederationService` is created. The server instance initialized using that function can be registered as a gRPC server using the `RegisterFederationService` function defined in `federation_grpc.pb.go` as is. When initializing, you need to create a dedicated `Config` structure and pass. ```go type ClientConfig struct{} func (c *ClientConfig) Post_PostServiceClient(cfg federation.FederationServiceClientConfig) (post.PostServiceClient, error) { // create by post.NewPostServiceClient() ... } func (c *ClientConfig) User_UserServiceClient(cfg federation.FederationServiceClientConfig) (user.UserServiceClient, error) { // create by user.NewUserServiceClient() ... } federationServer, err := federation.NewFederationService(federation.FederationServiceConfig{ // Client provides a factory that creates the gRPC Client needed to invoke methods of the gRPC Service on which the Federation Service depends. // If this interface is not provided, an error is returned during initialization. Client: new(ClientConfig), }) if err != nil { ... } grpcServer := grpc.NewServer() federation.RegisterFederationServiceServer(grpcServer, federationServer) ``` `Config` (e.g. `federation.FederationServiceConfig` ) must always be passed a configuration to initialize the gRPC Client, which is needed to invoke the methods on which the federation service depends. Also, there are settings for customizing error handling on method calls or logger, etc. ## 9. Other Examples [A sample that actually works can be found here](../_examples/) ================================================ FILE: docs/installation.md ================================================ # Installation There are currently three ways to use gRPC Federation. 1. Use `buf generate` 2. Use `protoc-gen-grpc-federation` 3. Use `grpc-federation-generator` ## 1. Use `buf generate` If your project can use [Buf](https://buf.build/), this is the easiest way. gRPC Federation is already registered with the Buf Registry. - Schema: https://buf.build/mercari/grpc-federation - Plugin: https://buf.build/community/mercari-grpc-federation Therefore, if you installed `buf` CLI, you can simply run the `buf generate` command to use gRPC Federation. [Documentation for Buf's code generation is here](https://buf.build/docs/generate/overview) Here is a sample of `buf.work.yaml` and `buf.gen.yaml`. - buf.work.yaml ```yaml version: v1 directories: - proto ``` - buf.gen.yaml ```yaml version: v1 managed: enabled: true plugins: - plugin: go out: gen opt: - paths=source_relative - plugin: go-grpc out: gen opt: - paths=source_relative - plugin: buf.build/community/mercari-grpc-federation:v1.0.0 out: gen opt: - paths=source_relative ``` Also, place `buf.yaml` under the `proto` directory. - proto/buf.yaml ```yaml version: v1 deps: - buf.build/mercari/grpc-federation lint: use: - DEFAULT breaking: use: - FILE ``` By writing `buf.build/mercari/grpc-federation` in `deps` section, it will find the gRPC Federation proto file. Finally, save the following proto as `proto/example.proto` and run `buf generate` to generate the results under `gen` directory. - proto/example.proto ```proto syntax = "proto3"; package example.bff; import "grpc/federation/federation.proto"; option go_package = "example/bff;bff"; service BFF { option (grpc.federation.service) = {}; rpc Get(GetRequest) returns (GetResponse) {}; } message GetRequest {} message GetResponse { option (grpc.federation.message).custom_resolver = true; } ``` ## 2. Use protoc-gen-grpc-federation ### 2.1. Install `protoc-gen-grpc-federation` `protoc-gen-grpc-federation` is a `protoc` plugin made by Go. It can be installed with the following command. ```console go install github.com/mercari/grpc-federation/cmd/protoc-gen-grpc-federation@latest ``` ### 2.2. Put gRPC Federation proto file to the import path Copy the gRPC Federation proto file to the import path. gRPC Federation's proto file is [here](./proto/grpc/federation/federation.proto). Also, gRPC Federation depends on the following proto file. These are located in the `proto_deps` directory and should be added to the import path if necessary. - [`google/rpc/code.proto`](./proto_deps/google/rpc/code.proto) - [`google/rpc/error_details.proto`](./proto_deps/google/rpc/error_details.proto) ```console git clone https://github.com/mercari/grpc-federation.git cd grpc-federation cp -r proto /path/to/proto cp -r proto_deps /path/to/proto_deps ``` ### 2.3. Use gRPC Federation proto file in your proto file. - my_federation.proto ```proto syntax = "proto3"; package mypackage; import "grpc/federation/federation.proto"; ``` ### 2.4. Run `protoc` command with gRPC Federation plugin ```console protoc -I/path/to/proto -I/path/to/proto_deps --grpc-federation_out=. ./path/to/my_federation.proto ``` ## 3. Use `grpc-federation-generator` `grpc-federation-generator` is an standalone generator that allows you to use the gRPC Federation code generation functionality without `protoc` plugin. Also, the code generated by gRPC Federation depends on the code generated by `protoc-gen-go` and `protoc-gen-go-grpc`, so it generates `file.pb.go` and `file_grpc.pb.go` files at the same time without that plugins. ( This behavior can be optionally disabled ) `grpc-federation-generator` also has the ability to monitor changes in proto files and automatically generate them, allowing you to perform automatic generation interactively. Combined with the existing hot-reloader tools, it allows for rapid Go application development. The version of the gRPC Federation proto is the version when `grpc-federation-generator` is built. ### 3.1. Install `grpc-federation-generator` `grpc-federation-generator` made by Go. It can be installed with the following command. ```console go install github.com/mercari/grpc-federation/cmd/grpc-federation-generator@latest ``` ### 3.2. Write configuration file for `grpc-federation-generator` Parameters to be specified when running `protoc` are described in `grpc-federation.yaml` - grpc-federation.yaml ```yaml # specify import paths. imports: - proto # specify the directory where your proto files are located. # In watch mode, files under these directories are recompiled and regenerated immediately when changes are detected. src: - proto # specify the destination of gRPC Federation's code-generated output. out: . # specify plugin options to be used during code generation of gRPC Federation. # The format of this plugins section is same as [buf.gen.yaml](https://buf.build/docs/configuration/v1/buf-gen-yaml#plugins). # Of course, other plugins can be specified, such as `buf.gen.yaml`. plugins: - plugin: go opt: paths=source_relative - plugin: go-grpc opt: paths=source_relative - plugin: grpc-federation opt: paths=source_relative ``` ### 3.3. Run `grpc-federation-generator` If a proto file is specified, code generation is performed on that file. ```console grpc-federation-generator ./path/to/my_federation.proto ``` When invoked with the `-w` option, it monitors changes to the proto files within the directories specified in `grpc-federation.yaml` and automatically compiles and generates code. ```console grpc-federation-generator -w ``` > [!NOTE] > In the future, we plan to implement a mechanism for code generation by other plugins in combination with `buf.work.yaml` and `buf.gen.yaml` definitions. ================================================ FILE: docs/references.md ================================================ # gRPC Federation Feature References # grpc.federation.service The `grpc.federation.service` option is **always required** to enable gRPC Federation. Please specify as follows. ```proto service MyService { option (grpc.federation.service) = {}; } ``` | field | type | required or optional | | ----- | ---- | ------------------- | | [`env`](#grpcfederationserviceenv) | Env | optional | | [`var`](#grpcfederationservicevar) | repeated ServiceVariable | optional | ## (grpc.federation.service).env The definition of environment variables used by the service. The environment variables defined here can be accessed through the `GetEnv()` function in the custom resolver. They can also be used by accessing the `grpc.federation.env` variable in CEL expressions. When using `grpc.federation.env` to access environment variables, the message using the option must exist in the same package as the service that defines the `env` option. Keep in mind that multiple services within the same package can use the `env` option. However, if a message is employed by multiple services with differing `env` options, that message can only access the set of environment variables that are common to those services. For instance, suppose ServiceA has two environment variables, `ENV_VAR1` and `ENV_VAR2`, while ServiceB has just one, `ENV_VAR1`. If both services reference `Message1`, users can only access `ENV_VAR1` from `Message1`, as ServiceB does not define `ENV_VAR2` in its environment options. `message` and `var` cannot be used simultaneously. | field | type | required or optional | | ----- | ---- | ------------------- | | [`message`](#grpcfederationserviceenvmessage) | string | optional | | [`var`](#grpcfederationserviceenvvar) | repeated EnvVar | optional | ## (grpc.federation.service).env.message If there is a message that represents a collection of environment variables, you can specify that message. ### Example If the following environment variables exist, they can be interpreted and handled as an `Env` message. - `FOO=hello` - `BAR=1` ```proto service MyService { option (grpc.federation.service) = { env { message: "Env" } }; } message Env { string foo = 1; int64 bar = 2; } ``` ## (grpc.federation.service).env.var The definition of the environment variable. | field | type | required or optional | | ----- | ---- | ------------------- | | [`name`](#grpcfederationserviceenvvarname) | string | required | | [`type`](#grpcfederationserviceenvvartype) | EnvType | required | | [`option`](#grpcfederationserviceenvvaroption) | EnvVarOption | optional | ## (grpc.federation.service).env.var.name The name of the environment variable.

This name can be referenced in all CELs related to the service by using `grpc.federation.var.` prefix. ## (grpc.federation.service).var.if If `if` is defined, then it is evaluated only if the condition is matched. If does not evaluated, a default value of the type obtained when evaluating is assigned. ## (grpc.federation.service).var.by Binds the result of evaluating the [CEL](./cel.md) defined in `by` to the variable defined in name. ## (grpc.federation.service).var.map Please see [(grpc.federation.message).def.map](#grpcfederationmessagedefmap). ## (grpc.federation.service).var.message Please see [(grpc.federation.message).def.message](#grpcfederationmessagedefmessage). ## (grpc.federation.service).var.enum Please see [(grpc.federation.message).def.enum](#grpcfederationmessagedefenum). ## (grpc.federation.service).var.switch Please see [(grpc.federation.message).def.switch](#grpcfederationmessagedefswitch). ## (grpc.federation.service).var.validation A validation rule against variables defined within the current scope. | field | type | required or optional | | ----- | ---- | ------------------- | | [`if`](#grpcfederationservicevarvalidationif) | [CEL](./cel.md) | required | | [`message`](#grpcfederationservicevarvalidationmessage) | [CEL](./cel.md) | required | ## (grpc.federation.service).var.validation.if A validation rule in [CEL](./cel.md). If the condition is true, the validation returns the error. The return value must always be of type boolean. ## (grpc.federation.service).var.validation.message A gRPC status message in case of validation error. # grpc.federation.method | field | type | required or optional | | ----- | ---- | ------------------- | | [`timeout`](#grpcfederationmethodtimeout) | string | optional | | [`response`](#grpcfederationmethodresponse) | string | optional | ## (grpc.federation.method).timeout the time to timeout. If the specified time period elapses, DEADLINE_EXCEEDED status is returned. If you want to handle this error, you need to implement a custom error handler in Go. The format is the same as Go's time.Duration format. See https://pkg.go.dev/time#ParseDuration. ### Example ```proto service MyService { option (grpc.federation.service) = {}; rpc Get(GetRequest) returns (GetResponse) { option (grpc.federation.method).timeout = "1m"; }; } ``` ## (grpc.federation.method).response `response` specify the name of the message you want to use to create the response value. If you specify a reserved type like `google.protobuf.Empty` as the response, you cannot define gRPC Federation options. In such cases, you can specify a separate message to create the response value. The specified response message must contain fields with the same names and types as all the fields in the original response. ### Example ```proto service MyService { option (grpc.federation.service) = {}; rpc Update(UpdateRequest) returns (google.protobuf.Empty) { option (grpc.federation.method).response = "UpdateResponse"; }; } message UpdateRequest { string id = 1; } message UpdateResponse { option (grpc.federation.message) = { def { call { method: "pkg.PostService/UpdatePost" request { field: "id" by: "$.id" } } } }; } ``` # grpc.federation.enum | field | type | required or optional | | ----- | ---- | ------------------- | | [`alias`](#grpcfederationenumalias) | string | optional | ## (grpc.federation.enum).alias `alias` mapping between enums defined in other packages and enums defined on the federation service side. The `alias` is the FQDN ( `.` ) to the enum. If this definition exists, type conversion is automatically performed before the enum value assignment operation. If a enum with this option has a value that is not present in the enum specified by alias, and the alias option is not specified for that value, an error is occurred. ### Example ```proto package mypkg; enum FooEnum { option (grpc.federation.enum).alias = "foopkg.FooEnum"; ENUM_VALUE_1 = 0; ENUM_VALUE_2 = 1; } ``` # grpc.federation.enum_value | field | type | required or optional | | ----- | ---- | ------------------- | | [`default`](#grpcfederationenum_valuedefault) | bool | optional | | [`alias`](#grpcfederationenum_valuealias) | repeated string | optional | | [`noalias`](#grpcfederationenum_valuenoalias) | bool | optional | | [`attr`](#grpcfederationenum_valueattr) | repeated EnumValueAttribute | optional | ## (grpc.federation.enum_value).default Specifies the default value of the enum. All values other than those specified in alias will be default values. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; enum FooEnum { option (grpc.federation.enum).alias = "foopkg.FooEnum"; ENUM_VALUE_UNKNOWN = 0 [(grpc.federation.enum_value).default = true]; ENUM_VALUE_1 = 1 [(grpc.federation.enum_value).alias = "FOO_VALUE_1"]; ENUM_VALUE_2 = 2 [(grpc.federation.enum_value).alias = "FOO_VALUE_2"]; } ``` - foo.proto ```proto package foopkg; enum FooEnum { FOO_VALUE_1 = 0; FOO_VALUE_2 = 1; FOO_VALUE_3 = 2; } ``` ## (grpc.federation.enum_value).alias `alias` can be used when alias is specified in `grpc.federation.enum` option, and specifies the value name to be referenced among the enums specified in alias of enum option. multiple value names can be specified for `alias`. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; enum FooEnum { option (grpc.federation.enum).alias = "foopkg.FooEnum"; ENUM_VALUE_1 = 0 [(grpc.federation.enum_value).alias = "FOO_VALUE_1"]; ENUM_VALUE_2 = 1 [(grpc.federation.enum_value).alias = "FOO_VALUE_2"]; } ``` - foo.proto ```proto package foopkg; enum FooEnum { FOO_VALUE_1 = 0; FOO_VALUE_2 = 1; } ``` ## (grpc.federation.enum_value).noalias `noalias` exclude from the target of `alias`. This option cannot be specified simultaneously with `default` or `alias`. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; enum FooEnum { option (grpc.federation.enum).alias = "foopkg.FooEnum"; ENUM_VALUE_1 = 0 [(grpc.federation.enum_value).alias = "FOO_VALUE_1"]; ENUM_VALUE_2 = 1 [(grpc.federation.enum_value).noalias = true]; } ``` ## (grpc.federation.enum_value).attr `attr` is used to hold multiple name-value pairs corresponding to an enum value. The values specified by the name must be consistently specified for all enum values. The values stored using this feature can be retrieved using the [`attr()`](./cel/enum.md#enum-fqdnattr) method of the enum API. ### Example ```proto package mypkg; message Foo { option (grpc.federation.message) = { def { name: "v" by: "Type.value('VALUE_1')" } }; string text = 1 [(grpc.federation.field).by = "Type.attr(v, 'attr_x')"]; } enum Type { VALUE_1 = 1 [(grpc.federation.enum_value).attr = { name: "attr_x" value: "foo" }]; VALUE_2 = 2 [(grpc.federation.enum_value).attr = { name: "attr_x" value: "bar" }]; } ``` # grpc.federation.message | field | type | required or optional | | ----- | ---- | -------------------- | | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`custom_resolver`](#grpcfederationmessagecustom_resolver) | bool | optional | | [`alias`](#grpcfederationmessagealias) | string | optional | ## (grpc.federation.message).def `def` can define variables. The defined variables can be referenced in subsequent [CEL](./cel.md) field. The `name` is a variable name and `autobind` can be used when the variable is `message` type. It can be used for automatic field binding. If `if` is defined, then it is evaluated only if the condition is matched. If does not evaluated, a default value of the type obtained when evaluating is assigned. | field | type | required or optional | | ----- | ---- | -------------------- | | [`name`](#grpcfederationmessagedefname) | string | optional | | [`autobind`](#grpcfederationmessagedefautobind) | bool | optional | | [`if`](#grpcfederationmessagedefif) | [CEL](./cel.md) | optional | The value to be assigned to a variable can be created with the following features. | field | type | required or optional | | ----- | ---- | -------------------- | | [`by`](#grpcfederationmessagedefby) | [CEL](./cel.md) | optional | | [`call`](#grpcfederationmessagedefcall) | CallExpr | optional | | [`message`](#grpcfederationmessagedefmessage) | MessageExpr | optional | | [`enum`](#grpcfederationmessagedefenum) | EnumExpr | optional | | [`map`](#grpcfederationmessagedefmap) | MapExpr | optional | | [`switch`](#grpcfederationmessagedefswitch) | SwitchExpr | optional | | [`validation`](#grpcfederationmessagedefvalidation) | ValidationExpr | optional | ## (grpc.federation.message).def.autobind If the defined value is a message type and the field of that message type exists in the message with the same name and type, the field binding is automatically performed. If multiple autobinds are used at the same message, you must explicitly use the `grpc.federation.field` option to do the binding yourself, since duplicate field names cannot be correctly determined as one. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" } // The value returned by `call` is `foopkg.GetFooReply` message. // In this case, if a field with the same name and type as the field in the `GetFooReply` message exists in `MyMessage`, // field binding is automatically performed. autobind: true } }; string field1 = 1; // autobound from `foopkg.GetFooReply.field1` bool field2 = 2; // autobound from `foopkg.GetFooReply.field2` } ``` - foo.proto ```proto package foopkg; service FooService { rpc GetFoo(GetFooRequest) returns (GetFooReply) {}; } message GetFooReply { string field1 = 1; bool field2 = 2; } ``` ## (grpc.federation.message).def.if ### Example ```proto message MyMessage { option (grpc.federation.message) = { // `x` is assigned `10` def { name: "x" if: "true" by: "10" } // `y` is assigned `0` def { name: "y" if: "false" by: "10" } }; } ``` ## (grpc.federation.message).def.by Binds the result of evaluating the [CEL](./cel.md) defined in `by` to the variable defined in name. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { // variable `v` is assigned the value `6`. name: "v" by: "1 + 2 + 3" } }; } ``` ## (grpc.federation.message).def.call `call` is used to call the gRPC method and assign the result to a variable. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { // The type of "res" variable is `foopkg.FooService/GetFoo` method's response type. name: "res" call { method: "foopkg.FooService/GetFoo" request { field: "field1", by: "'abcd'" } } } // The type of "foo" variable is foo's field type of GetFoo's response type. // If the variable type is a message type, `autobind` feature can be used. def { name: "foo" by: "res.foo" autobind: true } }; } ``` ### reference | field | type | required or optional | | ----- | ---- | -------------------- | | [`method`](#grpcfederationmessagedefcallmethod) | string | required | | [`request`](#grpcfederationmessagedefcallrequest) | repeated MethodRequest | optional | | [`timeout`](#grpcfederationmessagedefcalltimeout) | string | optional | | [`retry`](#grpcfederationmessagedefcallretry) | RetryPolicy | optional | | [`error`](#grpcfederationmessagedefcallerror) | repeated GRPCError | optional | ## (grpc.federation.message).def.call.method Specify the FQDN for the gRPC method. format is `./`. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" } } }; } ``` - foo.proto ```proto package foopkg; service FooService { rpc GetFoo(GetFooRequest) returns (GetFooReply) {}; } ``` ## (grpc.federation.message).def.call.request Specify the request parameters for the gRPC method. The `field` corresponds to the field name in the request message, and the `by` specifies which value is associated with the field. ### Example - myservice.proto ```proto package mypkg; import "foo.proto"; message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" request: [ { field: "field1", by: "'hello'" } ] } } }; } ``` - foo.proto ```proto package foopkg; service FooService { rpc GetFoo(GetFooRequest) returns (GetFooReply) {}; } message GetFooRequest { string field1 = 1; } ``` ### reference | field | type | required or optional | | ----- | ---- | -------------------- | | [`field`](#grpcfederationmessagedefcallrequestfield) | string | required | | [`by`](#grpcfederationmessagedefcallrequestby) | [CEL](./cel.md) | optional | ## (grpc.federation.message).def.call.request.field The field name of the request message. ## (grpc.federation.message).def.call.request.by `by` used to refer to a variable or message argument defined in a `grpc.federation.message` option by [CEL](./cel.md). You need to use `$.` to refer to the message argument. ## (grpc.federation.message).def.call.timeout The time to timeout. If the specified time period elapses, DEADLINE_EXCEEDED status is returned. If you want to handle this error, you need to implement a custom error handler in Go. The format is the same as Go's time.Duration format. See https://pkg.go.dev/time#ParseDuration. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" timeout: "1m" } } }; } ``` ## (grpc.federation.message).def.call.retry Specify the retry policy if the method call fails. | field | type | required or optional | | ----- | ---- | -------------------- | | [`if`](#grpcfederationmessagedefcallretryif) | [CEL](./cel.md) | optional | | [`constant`](#grpcfederationmessagedefcallretryconstant) | RetryPolicyConstant | optional | | [`exponential`](#grpcfederationmessagedefcallretryexponential) | RetryPolicyExponential | optional | ## (grpc.federation.message).def.call.retry.if `if` specifies condition in CEL. If the condition is `true`, run the retry process according to the policy. If this field is omitted, it is always treated as `true` and run the retry process. The return value must always be of type `boolean`. > [!NOTE] > Within the `if`, the `error` variable can be used as a gRPC error variable when evaluating CEL. > [A detailed description of this variable is here](./cel.md#error) ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { if: "error.code != google.rpc.Code.UNIMPLEMENTED" constant { interval: "10s" } } } } }; } ``` ## (grpc.federation.message).def.call.retry.constant Retry according to the "constant" policy. | field | type | required or optional | | ----- | ---- | -------------------- | | [`inerval`](#grpcfederationmessagedefcallretryconstantinterval) | string | optional | | [`max_retries`](#grpcfederationmessagedefcallretryconstantmax_retries) | uint64 | optional | ## (grpc.federation.message).def.call.retry.constant.interval Interval value. Default value is `1s`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { constant { interval: "10s" } } } } }; } ``` ## (grpc.federation.message).def.call.retry.constant.max_retries Max retry count. Default value is `5`. If `0` is specified, it never stops. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { constant { max_retries: 3 } } } } }; } ``` ## (grpc.federation.message).def.call.retry.exponential | field | type | required or optional | | ----- | ---- | -------------------- | | [`initial_interval`](#grpcfederationmessagedefcallretryexponentialinitial_interval) | string | optional | | [`randomization_factor`](#grpcfederationmessagedefcallretryexponentialrandomization_factor) | double | optional | | [`multiplier`](#grpcfederationmessagedefcallretryexponentialmultiplier) | double | optional | | [`max_interval`](#grpcfederationmessagedefcallretryexponentialmax_interval) | string | optional | | [`max_retries`](#grpcfederationmessagedefcallretryexponentialmax_retries) | uint64 | optional | ## (grpc.federation.message).def.call.retry.exponential.initial_interval Initial interval value. Default value is `500ms`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { exponential { initial_interval: "1s" } } } } }; } ``` ## (grpc.federation.message).def.call.retry.exponential.randomization_factor Randomization factor value. Default value is `0.5`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { exponential { randomization_factor: 1.0 } } } } }; } ``` ## (grpc.federation.message).def.call.retry.exponential.multiplier Multiplier. Default value is `1.5`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { exponential { multiplier: 1.0 } } } } }; } ``` ## (grpc.federation.message).def.call.retry.exponential.max_interval Max interval value. Default value is `60s`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { exponential { max_interval: "30s" } } } } }; } ``` ## (grpc.federation.message).def.call.retry.exponential.max_retries Max retry count. Default value is `5`. If `0` is specified, it never stops. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" retry { exponential { max_retries: 3 } } } } }; } ``` ## (grpc.federation.message).def.call.error ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" // If an error is returned when the gRPC method is called, the error block is evaluated. // If there are multiple error blocks, they are processed in order from the top. // The first error matching the condition is returned. // If none of the conditions match, the original error is returned. error { // The variables can be defined for use in error blocks def { name: "a" by: "1" } if: "a == 1" // if true, returns the error. code: FAILED_PRECONDITION // gRPC error code. this field is required. message: "'this is error message'" // gRPC error message. this field is required. // If you want to add the more information to the gRPC error, you can specify it in the details block. details { // The variables can be defined for use in details block. def { name: "b" by: "2" } if: "b == 2" // if true, add to the error details. // You can specify the value defined in `google/rpc/error_details.proto`. // FYI: https://github.com/googleapis/googleapis/blob/master/google/rpc/error_details.proto precondition_failure { violations { type: "'type value'" subject: "'subject value'" description: "'desc value'" } } // If you want to add your own message, you can add it using the message name and arguments as follows. message { name: "CustomMessage" args { name: "msg" by: "id" } } } } // This error block is evaluated if the above condition is false. error { // If `ignore: true` is specified, the error is ignored. ignore: true } } } }; } ``` | field | type | required or optional | | ----- | ---- | -------------------- | | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`if`](#grpcfederationmessagedefcallerrorif) | [CEL](./cel.md) | optional | | [`code`](#grpcfederationmessagedefcallerrorcode) | [google.rpc.Code](../proto_deps/google/rpc/code.proto) | required | | [`message`](#grpcfederationmessagedefcallerrormessage) | [CEL](./cel.md) | required | | `details` | repeated GRPCErrorDetail | optional | | [`ignore`](#grpcfederationmessagedefcallerrorignore) | bool | optional | | [`ignore_and_response`](#grpcfederationmessagedefcallerrorignore_and_response) | [CEL](./cel.md) | optional | > [!NOTE] > Within the error block, the `error` variable can be used as a special variable when evaluating CEL. > [A detailed description of this variable is here](./cel.md#error) ## (grpc.federation.message).def.call.error.def `def` defines a variable scoped to the entire error block. It is important to note that definitions scoped at the top level of the error block will be evaluated before `error.if`. ## (grpc.federation.message).def.call.error.if `if` specifies condition in CEL. If the condition is `true`, it returns defined error information. If this field is omitted, it is always treated as `true` and returns defined error information. The return value must always be of type `boolean`. ## (grpc.federation.message).def.call.error.code `code` is a gRPC status code. ## (grpc.federation.message).def.call.error.message `message` is a gRPC status message. If omitted, the message will be auto-generated from the configurations. ## (grpc.federation.message).def.call.error.ignore `ignore` ignore the error if the condition in the `if` field is `true` and `ignore` field is set to `true`. When an error is ignored, the returned response is always empty value. If you want to return a response that is not empty, please use `ignore_and_response` feature. Therefore, `ignore` and `ignore_and_response` cannot be specified same. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" error { // dscribe the condition for ignoring error. if: "error.code == google.rpc.Code.UNAVAILABLE" ignore: true } } } }; } ``` If you want to define custom processing using the original error value when an error is ignored, you can retrieve the contents of the error by calling the `ignoredError()` method on the return value. Additionally, you can check whether `ignoredError()` can be used by calling `hasIgnoredError()`. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { name: "res" call { method: "foopkg.FooService/GetFoo" error { // dscribe the condition for ignoring error. if: "error.code == google.rpc.Code.UNAVAILABLE" ignore: true } } } def { // It returns true if the error was being ignored. if: "res.hasIgnoredError()" // Binds error code to code variable ( google.rpc.Code.UNAVAILABLE ) name: "code" // Get original error variable by ignoredError method. by: "res.ignoredError().code" } }; } ``` ## (grpc.federation.message).def.call.error.ignore_and_response `ignore_and_response` ignore the error if the condition in the `if` field is `true` and it returns response specified in CEL. The evaluation value of CEL must always be the same as the response message type. `ignore` and `ignore_and_response` cannot be specified same. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { call { method: "foopkg.FooService/GetFoo" error { // dscribe the condition for ignoring error. if: "error.code == google.rpc.Code.UNAVAILABLE" // specify the response to return when errors are ignored. // The return value must always be a response message. ignore_and_response: "foopkg.Foo{x: 1}" } } } }; } ``` ## (grpc.federation.message).def.message `message` used to refer to other message. The parameters necessary to obtain a message must be passed as message arguments by `args`. | field | type | required or optional | | ----- | ---- | -------------------- | | [`name`](#grpcfederationmessagedefmessagename) | string | required | | [`args`](#grpcfederationmessagedefmessageargs) | repeated Argument | optional | ## (grpc.federation.message).def.message.name Specify the message name with FQDN. format is `.`. `` can be omitted when referring to messages in the same package. ### Example ```proto package mypkg; message MyMessage { option (grpc.federation.message) = { // get the `Foo` message and assign it to the `foo` variable. def { name: "foo" message { name: "Foo" } } }; } message Foo { option (grpc.federation.message).custom_resolver = true; string x = 1; } ``` ## (grpc.federation.message).def.message.args Specify the parameters needed to retrieve the message. This is called the message argument. ### Example ```proto package mypkg; message MyMessage { option (grpc.federation.message) = { def { name: "foo" message { name: "Foo" // pass arguments to retrieve Foo message. args [ { name: "x" by: "'xxxx'" }, { name: "y" by: "true" } ] } } }; } message Foo { // $.x is `xxxx` value string x = 1 [(grpc.federation.field).by = "$.x"]; // $.y is `true` value bool y = 2 [(grpc.federation.field).by = "$.y"]; } ``` ### reference | field | type | required or optional | | ----- | ---- | -------------------- | | [`name`](#grpcfederationmessagedefmessageargsname) | string | required | | [`by`](#grpcfederationmessagedefmessageargsby) | [CEL](./cel.md) | optional | | [`inline`](#grpcfederationmessagedefmessageargsinline) | [CEL](./cel.md) | optional | ## (grpc.federation.message).def.message.args.name Name of the message argument. Use this name to refer to the message argument. For example, if `foo` is specified as the name, it is referenced by `$.foo` in dependent message. ## (grpc.federation.message).def.message.args.by `by` used to refer to a variable or message argument defined in a `grpc.federation.message` option by [CEL](./cel.md). You need to use `$.` to refer to the message argument. ## (grpc.federation.message).def.message.args.inline `inline` like `by`, it refers to the specified value and expands all fields beyond it. For this reason, the referenced value must always be of message type. ## (grpc.federation.message).def.enum `enum` is a feature designed to create enum values defined in the federation package. If you want to create enum values in the federation package based on enum values defined in a dependency package, this feature will be useful. ### Example In this example, the value of `dep.Type.TYPE_1` is converted to the type `mypkg.MyType`. If the conversion fails, it is logged. ```proto package mypkg; message MyMessage { option (grpc.federation.message) = { def { name: "v" enum { name: "MyType" by: "dep.Type.TYPE_1" } } def { if: "v == MyType.TYPE_UNSPECIFIED" by: "grpc.federation.log.warn('got unexpected type')" } }; } enum MyType { option (grpc.federation.enum).alias = "dep.Type"; TYPE_UNSPECIFIED = 1 [(grpc.federation.enum_value).default = true]; TYPE_1 = 2; TYPE_2 = 3; } ``` ```proto package dep; enum Type { TYPE_1 = 1; TYPE_2 = 2; } ``` ## (grpc.federation.message).def.map | field | type | required or optional | | ----- | ---- | -------------------- | | [`iterator`](#grpcfederationmessagedefmapiterator) | Iterator | required | | [`by`](#grpcfederationmessagedefmapby) | [CEL](./cel.md) | optional | | [`message`](#grpcfederationmessagedefmapmessage) | MessageExpr | optional | | [`enum`](#grpcfederationmessagedefmapenum) | EnumExpr | optional | ## (grpc.federation.message).def.map.iterator Create the iterator variable. - `src` must be a repeated type - `name` defines the name of the iterator variable ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { name: "foo_list" message { name: "FooList" } } def { // `list_x` value is a list of Foo.x. The type is repeated string. name: "list_x" map { iterator { // iterator variable name is `iter`. name: "iter" // refer to FooList message's `foos` field. src: "foo_list.foos" } // refer to `iter` variable and returns x field value. by: "iter.x" } } }; } message FooList { option (grpc.federation.message).custom_resolver = true; repeated Foo foos = 1; } message Foo { string x = 1; } ``` ### reference | field | type | required or optional | | ----- | ---- | -------------------- | | [`name`](#grpcfederationmessagedefmapiteratorname) | string | required | | [`src`](#grpcfederationmessagedefmapiteratorsrc) | [CEL](./cel.md) | required | ## (grpc.federation.message).def.map.iterator.name The name of the iterator variable. ## (grpc.federation.message).def.map.iterator.src The variable of repeated type that form the basis of iterator. ## (grpc.federation.message).def.map.by Create map elements using [`CEL`](./cel.md) by referencing variables created with `iterator` section. ## (grpc.federation.message).def.map.message Create map elements using `message` value by referencing variables created with `iterator` section. ## (grpc.federation.message).def.map.enum Create map elements using `enum` value by referencing variables created with `iterator` section. ## (grpc.federation.message).def.switch `switch` evaluates cases in order and returns the value from the first matching case, or the default case, if no case matches. | field | type | required or optional | | --------------------------------------------------- | ----------------------- | -------------------- | | [`case`](#grpcfederationmessagedefswitchcase) | repeated SwitchCaseExpr | optional | | [`default`](#grpcfederationmessagedefswitchdefault) | SwitchDefaultExpr | required | ### Example ```proto message MyMessage { option (.grpc.federation.message) = { def { name: "status" switch { case { if: "$.activation_status == 'active'" by: "'enabled'" } case { if: "$.activation_status == 'inactive'" by: "'disabled'" } default { by: "'unknown'" } } } }; string status = 1 [(grpc.federation.field).by = "status"]; } ``` ## (grpc.federation.message).def.switch.case A single case in a `switch` expression. Cases are evaluated in order, and the first case whose `if` condition evaluates to `true` will have its `by` expression evaluated and the resulting value returned as the value of the `switch`. | field | type | required or optional | | --------------------------------------------- | --------------------------- | -------------------- | | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`if`](#grpcfederationmessagedefswitchcaseif) | [CEL](./cel.md) | required | | [`by`](#grpcfederationmessagedefswitchcaseby) | [CEL](./cel.md) | required | ## (gprc.federation.message).def.switch.case.def `def` defines a variable scoped to the case block. It is important to note that definitions scoped at the top level of the case block will be evaluated after `case.if` and before `case.by`. ## (grpc.federation.message).def.switch.case.if A condition in [CEL](./cel.md) that determines whether this case matches. The return value must always be of type boolean. If the condition evaluates to `true`, the case matches and its `by` expression is evaluated. ## (grpc.federation.message).def.switch.case.by A [CEL](./cel.md) expression that is evaluated when this case matches. The result of this expression is returned as the value of the `switch` expression. ## (grpc.federation.message).def.switch.default The default case that is evaluated when none of the switch cases match. Variables local to the scope of the default case can be defined in `def`. | field | type | required or optional | | ------------------------------------------------ | --------------------------- | -------------------- | | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`by`](#grpcfederationmessagedefswitchdefaultby) | [CEL](./cel.md) | required | ## (gprc.federation.message).def.switch.default.def `def` defines a variable scoped to the default block. It is important to note that definitions scoped at the top level of the default block will be evaluated before `case.by`. ## (grpc.federation.message).def.switch.default.by A [CEL](./cel.md) expression that is evaluated when no switch case matches. The result of this expression is returned as the value of the `switch` expression. ## (grpc.federation.message).def.validation A validation rule against variables defined within the current scope. | field | type | required or optional | |-----------------------------------------------------|-----------------|----------------------| | [`name`](#grpcfederationmessagedefvalidationname) | string | optional | | [`error`](#grpcfederationmessagedefvalidationerror) | ValidationError | required | ## (grpc.federation.message).def.validation.name A unique name for the validation. If set, the validation error type will be Error. If omitted, the validation error type will be ValidationError. ## (grpc.federation.message).def.validation.error A validation rule and validation error to be returned. Variables local to the scope of the validation error can be defined with `def`. | field | type | required or optional | |--------------------------------------------------------------|--------------------------------|----------------------| | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`code`](#grpcfederationmessagedefvalidationerrorcode) | [google.rpc.Code](../proto_deps/google/rpc/code.proto) | required | | [`message`](#grpcfederationmessagedefvalidationerrormessage) | string | optional | | [`if`](#grpcfederationmessagedefvalidationerrorif) | [CEL](./cel.md) | optional | | [`details`](#grpcfederationmessagedefvalidationerrordetails) | repeated ValidationErrorDetail | optional | ## (grpc.federation.message).def.validation.error.def `def` defines a variable scoped to the error block. It is important to note that definitions scoped at the top level of the error block will be evaluated before `error.if`. ## (grpc.federation.message).def.validation.error.code A gRPC status code to be returned in case of validation error. For the available Enum codes, check [googleapis/google/rpc /code.proto](https://github.com/googleapis/googleapis/blob/89b562b76f5b215990a20d3ea08bc6e1c0377906/google/rpc/code.proto#L32-L186). ## (grpc.federation.message).def.validation.error.message A gRPC status message in case of validation error. If omitted, the message will be auto-generated from the configurations. ## (grpc.federation.message).def.validation.error.if A validation rule in [CEL](./cel.md). If the condition is true, the validation returns the error. The return value must always be of type boolean. Either `if` or `details` must be specified. ### Example ```proto message MyMessage { option (grpc.federation.message) = { def { validation { name: "myMessageValidation", error { code: FAILED_PRECONDITION message: "MyMessage validation failed", if: "$.id == 'wrong'" } } } }; ... } ``` ## (grpc.federation.message).def.validation.error.details `details` is a list of validation rules and error details. If the validation fails, the corresponding error details are set. Either `if` or `details` must be specified. The other error detail types will be supported soon. | field | type | required or optional | |----------------------------------------------------------------------------------------------|-----------------------------------------|----------------------| | [`def`](#grpcfederationmessagedef) | repeated VariableDefinition | optional | | [`if`](#grpcfederationmessagedefvalidationerrordetailsif) | [CEL](./cel.md) | required | | [`by`](#grpcfederationmessagedefvalidationerrordetailsby) | repeated [CEL](./cel.md) | optional | | [`message`](#grpcfederationmessagedefvalidationerrordetailsmessage) | repeated MessageExpr | optional | | [`precondition_failure`](#grpcfederationmessagedefvalidationerrordetailspreconditionfailure) | repeated google.rpc.PreconditionFailure | optional | | [`bad_request`](#grpcfederationmessagedefvalidationerrordetailsbadrequest) | repeated google.rpc.BadRequest | optional | | [`localized_message`](#grpcfederationmessagedefvalidationerrordetailslocalizedmessage) | repeated google.rpc.LocalizedMessage | optional | ```proto message MyMessage { option (grpc.federation.message) = { def { validation { name: "myMessageValidation", error { code: FAILED_PRECONDITION message: "MyMessage validation failed", details { if: "$.id == 'wrong'", by: "pkg.Message{field: value}" message { name: "ErrorMessage", args { name: "message", by: "'some message'" } } precondition_failure { violations { type: "'some-type'" subject: "'some-subject'" description: "'some-desc'" } } bad_request { field_violations { field: "'some-field'" description: "'some-desc'" } } localized_message { locale: "en-US" message: "'some message'" } } } } } }; ... } ``` ## (grpc.federation.message).def.validation.error.details.def `def` defines a variable scoped to the error details block. It is important to note that definitions scoped at the top level of the error detail block will be evaluated before `details.if`. ## (grpc.federation.message).def.validation.error.details.if `if` specifies validation rule in [CEL](./cel.md). If the condition is true, the validation returns an error with the specified details. ## (grpc.federation.message).def.validation.error.details.by `by` specify a message in [CEL](./cel.md) to express the details of the error. ## (grpc.federation.message).def.validation.error.details.message `message` represents arbitrary proto messages to describe the error detail. ## (grpc.federation.message).def.validation.error.details.precondition_failure `precondition_failure` describes what preconditions have failed. See [google.rpc.PreconditionFailure](https://github.com/googleapis/googleapis/blob/89b562b76f5b215990a20d3ea08bc6e1c0377906/google/rpc/error_details.proto#L144) for the details. ## (grpc.federation.message).def.validation.error.details.bad_request `bad_request` describes violations in a client request. See [google.rpc.BadRequest](https://github.com/googleapis/googleapis/blob/89b562b76f5b215990a20d3ea08bc6e1c0377906/google/rpc/error_details.proto#L170) for the details. ## (grpc.federation.message).def.validation.error.details.localized_message `localized_message` provides a localized error message that is safe to return to the user. See [google.rpc.BadRequest](https://github.com/googleapis/googleapis/blob/89b562b76f5b215990a20d3ea08bc6e1c0377906/google/rpc/error_details.proto#L277) for the details. ## (grpc.federation.message).custom_resolver There is a limit to what can be expressed in proto, so if you want to execute a process that cannot be expressed in proto, you will need to implement it yourself in the Go language. If custom_resolver is true, the resolver for this message is implemented by Go. If there are any values retrieved by `def`, they are passed as arguments for custom resolver. Each field of the message returned by the custom resolver is automatically bound. If you want to change the binding process for a particular field, set `custom_resolver=true` option for that field. ### Example ```proto message Foo { option (grpc.federation.message).custom_resolver = true; } ``` or ```proto message Foo { User user = 1 [(grpc.federation.field).custom_resolver = true]; } ``` ## (grpc.federation.message).alias `alias` mapping between messages defined in other packages and messages defined on the federation service side. The `alias` is the FQDN ( `.` ) to the message. If this definition exists, type conversion is automatically performed before the field assignment operation. If a message with this option has a field that is not present in the message specified by alias, and the alias option is not specified for that field, an error is occurred. # grpc.federation.field | field | type | required or optional | | ----- | ---- | -------------------- | | [`by`](#grpcfederationfieldby) | string | optional | | [`oneof`](#grpcfederationfieldoneof) | FieldOneof | optional | | [`custom_resolver`](#grpcfederationfieldcustom_resolver) | bool | optional | | [`alias`](#grpcfederationfieldalias) | string | optional | ## (grpc.federation.field).by `by` used to refer to a variable or message argument defined in a `grpc.federation.message` option by [CEL](./cel.md). You need to use `$.` to refer to the message argument. ## (grpc.federation.field).oneof `oneof` used to directly assign a value to a field defined by `oneof`. | field | type | required or optional | | ----- | ---- | -------------------- | | [`if`](#grpcfederationfieldoneofif) | [CEL](./cel.md) | optional | | [`default`](#grpcfederationfieldoneofdefault) | bool | optional | | [`def`](#grpcfederationfieldoneofdef) | repeated VariableDefinition | optional | | [`by`](#grpcfederationfieldoneofby) | [CEL](./cel.md) | optional | ## (grpc.federation.field).oneof.if `if` is the condition to be assigned to oneof field. The return value must be of bool type. ## (grpc.federation.field).oneof.default `default` used to assign a value when none of the other fields match any of the specified expressions. Only one value can be defined per oneof. ## (grpc.federation.field).oneof.def `def` defines the list of variables to which the oneof field refers. ## (grpc.federation.field).oneof.by `by` used to refer to a variable or message argument defined in a `grpc.federation.message` and `grpc.federation.field.oneof` by [CEL](./cel.md). You need to use `$.` to refer to the message argument. ## (grpc.federation.field).custom_resolver If custom_resolver is true, the field binding process is to be implemented in Go. If there are any values retrieved by `grpc.federation.message` option, they are passed as arguments for custom resolver. ## (grpc.federation.field).alias `alias` can be used when `alias` is specified in `grpc.federation.message` option, and specifies the field name to be referenced among the messages specified in `alias` of message option. If the specified field has the same type or can be converted automatically, its value is assigned. # Message Argument Message argument is an argument passed when depends on other messages via the `def.message` feature. This parameter propagates the information necessary to resolve message dependencies. Normally, only values explicitly specified in `args` can be referenced as message arguments. However, exceptionally, a field in the gRPC method's request message can be referenced as a message argument to the method's response. For example, consider the `GetPost` method of the `FederationService`: the `GetPostReply` message implicitly allows the fields of the `GetPostRequest` message to be used as message arguments. In summary, it looks like this. 1. For the response message of rpc, the request message fields are the message arguments. 2. For other messages, the parameters explicitly passed in `def.message.args` option are the message arguments. 3. You can access to the message argument with `$.` prefix. ================================================ FILE: generator/code_generator.go ================================================ package

list-based UI for Proto Import Paths configuration - Enable/disable toggle for individual import paths - File browser dialog for adding and editing paths - Path validation feature to check if directories exist - Variable expansion support for `~/` and `${PROJECT_ROOT}` - Toolbar buttons for add, remove, and reorder operations - "Validate Paths" button to verify all configured paths - Semantic tokens support for enhanced syntax highlighting of gRPC Federation annotations - Token type mappings for proper colorization of proto elements - Explicit semantic tokens request for proto files ### Changed - Redesigned settings interface from single text field to table-based UI - Improved path management with better visual feedback - Enhanced user experience for managing multiple import paths - Migrated settings storage format from simple string list to structured entries with enable/disable state - Updated to IntelliJ Platform Gradle Plugin 2.7.2 (latest) - Updated to Platform Version 2024.3.3 with Kotlin 2.1.0 - Updated JVM toolchain from Java 17 to Java 21 (recommended for 2024.3.3) - Changed LSP server descriptor from ProjectWideLspServerDescriptor to LspServerDescriptor for proper semantic tokens support ### Fixed - Issue with paths containing spaces in the previous text field approach - Better handling of empty and invalid path entries - Checkbox display issue in the Enabled column with explicit renderer and editor - Diagnostic messages containing HTML tags (like ``) are now properly escaped to prevent UI rendering issues ### Deprecated - `importPaths` field in settings storage (will be removed in v0.3.0) - Automatic migration: Existing configurations will be automatically converted to the new format - The plugin maintains backward compatibility by reading from both old and new formats - Only the new `importPathEntries` format will be supported from v0.3.0 onwards ## [0.1.0] ### Added - Initial release of gRPC Federation IntelliJ plugin - Basic Language Server Protocol (LSP) integration - Proto import paths configuration - Support for `.proto` files with gRPC Federation annotations ================================================ FILE: lsp/client/jetbrains/README.md ================================================ # gRPC Federation Language Server for JetBrains The gRPC Federation Language Server for JetBrains is a plugin designed for JetBrains IDEs to integrate with the gRPC Federation language server, providing enhanced development experience for Protocol Buffer files with gRPC Federation annotations. ## Features - **Go to Definition** - Navigate to proto message and field definitions - **Diagnostics** - Real-time error detection and validation - **Code Completion** - Intelligent suggestions for gRPC Federation annotations ## Requirements - **IntelliJ IDEA Ultimate** 2023.3 or newer (This plugin requires Ultimate Edition) - **grpc-federation-language-server** installed and available in PATH ## Installation ### Step 1: Install the Language Server The plugin requires `grpc-federation-language-server` to be accessible in the system PATH. If Go is available, install it with: ```console $ go install github.com/mercari/grpc-federation/cmd/grpc-federation-language-server@latest ``` Verify the installation: ```console $ which grpc-federation-language-server ``` ### Step 2: Install the Plugin Install the plugin from JetBrains Marketplace: 1. Open **Settings/Preferences** → **Plugins** 2. Select **Marketplace** tab 3. Search for **"gRPC Federation"** 4. Click **Install** and restart the IDE ## Configuration ### Setting Import Paths Configure proto import paths for the language server to resolve dependencies: 1. Navigate to **Settings/Preferences** → **Tools** → **gRPC Federation** 2. In the **Proto Import Paths** section: - Click **+** to add a new path - Use the file browser to select directories - Enable/disable paths using checkboxes - Reorder paths using ↑/↓ buttons - Click **Validate Paths** to verify all directories exist ### Supported Path Variables - `~/` - User's home directory - `${PROJECT_ROOT}` - Current project root directory Example paths: ``` /usr/local/include ${PROJECT_ROOT}/proto ~/workspace/shared-protos ``` ## Troubleshooting ### Language Server Not Found If you see "grpc-federation-language-server not found" error: 1. Ensure the language server is installed (see Installation section) 2. Check if it's in your PATH: `which grpc-federation-language-server` 3. Restart the IDE after installation ### Proto Files Not Recognized If proto files are not being analyzed: 1. Ensure the file extension is `.proto` 2. Check that import paths are correctly configured 3. Validate paths using the **Validate Paths** button 4. Check the IDE logs: **Help** → **Show Log in Finder/Explorer** ### Import Resolution Issues If imports are not being resolved: 1. Add all necessary proto directories to import paths 2. Ensure paths are in the correct order (more specific paths first) 3. Check that all proto dependencies are available ## Support - **Issues**: [GitHub Issues](https://github.com/mercari/grpc-federation/issues) - **Documentation**: [gRPC Federation Documentation](https://github.com/mercari/grpc-federation) ================================================ FILE: lsp/client/jetbrains/build.gradle.kts ================================================ import org.jetbrains.changelog.Changelog import org.jetbrains.changelog.markdownToHTML import org.jetbrains.intellij.platform.gradle.TestFrameworkType fun properties(key: String) = providers.gradleProperty(key) fun environment(key: String) = providers.environmentVariable(key) plugins { id("java") // Java support alias(libs.plugins.kotlin) // Kotlin support alias(libs.plugins.gradleIntelliJPlugin) // Gradle IntelliJ Platform Plugin alias(libs.plugins.changelog) // Gradle Changelog Plugin alias(libs.plugins.qodana) // Gradle Qodana Plugin alias(libs.plugins.kover) // Gradle Kover Plugin } group = properties("pluginGroup").get() version = properties("pluginVersion").get() // Configure project's dependencies repositories { mavenCentral() // IntelliJ Platform Gradle Plugin Repositories Extension - read more: https://plugins.jetbrains.com/docs/intellij/tools-intellij-platform-gradle-plugin-repositories-extension.html intellijPlatform { defaultRepositories() } } // Dependencies are managed with Gradle version catalog - read more: https://docs.gradle.org/current/userguide/platforms.html#sub:version-catalog dependencies { // implementation(libs.annotations) // IntelliJ Platform Gradle Plugin Dependencies Extension - read more: https://plugins.jetbrains.com/docs/intellij/tools-intellij-platform-gradle-plugin-dependencies-extension.html intellijPlatform { create(properties("platformType"), properties("platformVersion")) // Plugin Dependencies.

# gRPC Federation Language Server for VSCode



## Features

### Syntax Highlighting

Semantic Highlighting allows for accurate recognition of gRPC Federation options.
Syntax highlighting is available in quoted value. So, this is especially effective in CEL value.



### Goto Definition

It supports jumps to the following definition sources.

- Imported file name
  - e.g.) import "path/to/foo.proto"

- Type of field definition
  - e.g.) Foo foo = 1

- gRPC method name
  - e.g.) def { call { method: "foopkg.FooService/BarMethod" } }

- Alias name
  - e.g.) option (grpc.federation.message).alias = "foopkg.Bar"


### Diagnostics
### Code Completion

## Install

To use this extension, `grpc-federation-language-server` is required.

If already installed Go in your local environment, please run the following command.

```console
$ go install github.com/mercari/grpc-federation/cmd/grpc-federation-language-server@latest
```

## Settings

The following options can be set in `.vscode/settings.json` .

The example settings is here.

```json
{
    "grpc-federation": {
        "path": "/path/to/grpc-federation-language-server",
        "import-paths": [
          "./proto"
        ]
    }
}
```

### path

Specify the path to the location where `grpc-federation-language-server` is installed.
If the installation location has already been added to your `PATH` environment variable, you do not need to specify this.

### import-paths

Specifies the path to search for proto files.
