It offers a clean and interactive TUI (Text User Interface) to provide real-time insights into your web application’s performance. Inspired by `trinhminhtriet/blast`, Spiko helps you simulate load and monitor the results in an intuitive and easy-to-understand interface.\n\n![Spiko](docs/images/demo.gif)\n\n## ✨ Features\n\n- πŸš€ High-performance load testing with minimal overhead\n- 🎨 Real-time TUI with beautiful, interactive graphs\n- ⚑ Powered by Rust and Tokio for fast, reliable results\n- πŸ§‘β€πŸ’» Simple configuration with easy-to-understand commands\n- πŸ“Š Visual feedback on request rates, latency, and more\n\n## πŸš€ Installation\n\nTo install **spiko**, simply clone the repository and follow the instructions below:\n\n```bash\ngit clone git@github.com:trinhminhtriet/spiko.git\ncd spiko\n\ncargo build --release\ncp ./target/release/spiko /usr/local/bin/\nspiko --version\nspiko --help\nspiko -n 1000 https://github.com\n```\n\nRunning the below command will globally install the `spiko` binary.\n\n```bash\ncargo install spiko\n```\n\nOptionally, you can add `~/.cargo/bin` to your PATH if it's not already there\n\n```bash\necho 'export PATH=\"$HOME/.cargo/bin:$PATH\"' >> ~/.bashrc\nsource ~/.bashrc\n```\n\n## πŸ’‘ Usage\n\n```\nUsage: spiko [OPTIONS] \n\nArguments:\n Target URL.\n\nOptions:\n -n \n Number of requests to run. [default: 200]\n -c \n Number of connections to run concurrently. You may should increase limit to number of open files for larger `-c`. [default: 50]\n -p \n Number of parallel requests to send on HTTP/2. `spiko` will run c * p concurrent workers in total. [default: 1]\n -z \n Duration of application to send requests. If duration is specified, n is ignored.\n On HTTP/1, When the duration is reached, ongoing requests are aborted and counted as \"aborted due to deadline\"\n You can change this behavior with `-w` option.\n Currently, on HTTP/2, When the duration is reached, ongoing requests are waited. `-w` option is ignored.\n Examples: -z 10s -z 3m.\n -w, --wait-ongoing-requests-after-deadline\n When the duration is reached, ongoing requests are waited\n -q \n Rate limit for all, in queries per second (QPS)\n --burst-delay \n Introduce delay between a predefined number of requests.\n Note: If qps is specified, burst will be ignored\n --burst-rate \n Rates of requests for burst. Default is 1\n Note: If qps is specified, burst will be ignored\n --rand-regex-url\n Generate URL by rand_regex crate but dot is disabled for each query e.g. http://127.0.0.1/[a-z][a-z][0-9]. Currently dynamic scheme, host and port with keep-alive are not works well. See https://docs.rs/rand_regex/latest/rand_regex/struct.Regex.html for details of syntax.\n --max-repeat \n A parameter for the '--rand-regex-url'. The max_repeat parameter gives the maximum extra repeat counts the x*, x+ and x{n,} operators will become. [default: 4]\n --dump-urls \n Dump target Urls times to debug --rand-regex-url\n --latency-correction\n Correct latency to avoid coordinated omission problem. It's ignored if -q is not set.\n --no-tui\n No realtime tui\n -j, --json\n Print results as JSON\n --fps \n Frame per second for tui. [default: 16]\n -m, --method \n HTTP method [default: GET]\n -H \n Custom HTTP header. Examples: -H \"foo: bar\"\n -t \n Timeout for each request. Default to infinite.\n -A \n HTTP Accept Header.\n -d \n HTTP request body.\n -D \n HTTP request body from file.\n -T \n Content-Type.\n -a \n Basic authentication, username:password\n --http-version \n HTTP version. Available values 0.9, 1.0, 1.1.\n --http2\n Use HTTP/2. Shorthand for --http-version=2\n --host \n HTTP Host header\n --disable-compression\n Disable compression.\n -r, --redirect \n Limit for number of Redirect. Set 0 for no redirection. Redirection isn't supported for HTTP/2. [default: 10]\n --disable-keepalive\n Disable keep-alive, prevents re-use of TCP connections between different HTTP requests. This isn't supported for HTTP/2.\n --no-pre-lookup\n *Not* perform a DNS lookup at beginning to cache it\n --ipv6\n Lookup only ipv6.\n --ipv4\n Lookup only ipv4.\n --insecure\n Accept invalid certs.\n --connect-to \n Override DNS resolution and default port numbers with strings like 'example.org:443:localhost:8443'\n --disable-color\n Disable the color scheme.\n --unix-socket \n Connect to a unix socket instead of the domain in the URL. Only for non-HTTPS URLs.\n --stats-success-breakdown\n Include a response status code successful or not successful breakdown for the time histogram and distribution statistics\n --db-url \n Write succeeded requests to sqlite database url E.G test.db\n --debug\n Perform a single request and dump the request and response\n -h, --help\n Print help\n -V, --version\n Print version\n```\n\n## πŸ—‘οΈ Uninstallation\n\nRunning the below command will globally uninstall the `spiko` binary.\n\n```bash\ncargo uninstall spiko\n```\n\nRemove the project repo\n\n```bash\nrm -rf /path/to/git/clone/spiko\n```\n\n## 🀝 How to contribute\n\nWe welcome contributions!\n\n- Fork this repository;\n- Create a branch with your feature: `git checkout -b my-feature`;\n- Commit your changes: `git commit -m \"feat: my new feature\"`;\n- Push to your branch: `git push origin my-feature`.\n\nOnce your pull request has been merged, you can delete your branch.\n\n## πŸ™ Acknowledgements\n\n- [hatoo/oha](https://github.com/hatoo/oha)\n\n## πŸ“ License\n\nThis project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details.\n" }, { "path": "demo.tape", "content": "Output media/demo.gif\n\nSet FontSize 16\nSet Width 1440\nSet Height 768\nSet TypingSpeed 400ms\n\nType@100ms \"echo 'https://trinhminhtriet.com'\"\nSleep 50ms\nEnter\n\nType@50ms \"spiko --version\"\nSleep 50ms\nEnter\nSleep 100ms\n\nType@50ms \"spiko --help\"\nSleep 50ms\nEnter\nSleep 100ms\n\nType@20ms \"spiko -n 1000 https://github.com\"\nSleep 100ms\nEnter\nSleep 20s\n" }, { "path": "pgo/server/Cargo.toml", "content": "[package]\nname = \"server\"\nversion = \"0.1.0\"\nedition = \"2021\"\n\n# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html\n\n[dependencies]\naxum = \"0.8.1\"\ntokio = { version = \"1\", features = [\"full\"] }\n" }, { "path": "pgo/server/src/main.rs", "content": "use std::net::SocketAddr;\nuse tokio::net::TcpListener;\n\nuse axum::{routing::get, Router};\n\n#[tokio::main]\nasync fn main() {\n // build our application with a route\n let app = Router::new()\n // `GET /` goes to `root`\n .route(\"/\", get(root));\n\n // run our app with hyper\n // `axum::Server` is a re-export of `hyper::Server`\n let addr = SocketAddr::from(([127, 0, 0, 1], 8888));\n let listener = TcpListener::bind(&addr).await.unwrap();\n axum::serve(listener, app).await.unwrap();\n}\n\nasync fn root() -> &'static str {\n \"Hello, World!\"\n}\n" }, { "path": "pgo.js", "content": "import { $ } from \"bun\";\n\nlet additional = [];\n\nif (Bun.argv.length >= 3) {\n additional = Bun.argv.slice(2);\n}\n\nlet server = null;\n\ntry {\n server = Bun.spawn(['cargo', 'run', '--release', '--manifest-path', 'pgo/server/Cargo.toml']);\n await $`cargo pgo run -- --profile pgo ${additional} -- -z 3m -c 900 --no-tui http://localhost:8888`;\n await $`cargo pgo optimize build -- --profile pgo ${additional}`\n} finally {\n if (server !== null) {\n server.kill();\n }\n}\n" }, { "path": "schema.json", "content": "{\n \"$schema\": \"http://json-schema.org/draft-04/schema#\",\n \"description\": \"JSON schema for the output of the `spiko -j`\",\n \"type\": \"object\",\n \"properties\": {\n \"summary\": {\n \"description\": \"Important statistics\",\n \"type\": \"object\",\n \"properties\": {\n \"successRate\": {\n \"description\": \"The number of success requests / All requests which isn't includes deadline\",\n \"type\": \"number\"\n },\n \"total\": {\n \"description\": \"Total duration in seconds\",\n \"type\": \"number\"\n },\n \"slowest\": {\n \"description\": \"The slowest request duration in seconds\",\n \"type\": \"number\"\n },\n \"fastest\": {\n \"description\": \"The fastest request duration in seconds\",\n \"type\": \"number\"\n },\n \"average\": {\n \"description\": \"The average request duration in seconds\",\n \"type\": \"number\"\n },\n \"requestsPerSec\": {\n \"description\": \"The number of requests per second\",\n \"type\": \"number\"\n },\n \"totalData\": {\n \"description\": \"Total data of HTTP bodies in bytes\",\n \"type\": \"integer\"\n },\n \"sizePerRequest\": {\n \"description\": \"The average size of HTTP bodies in bytes\",\n \"type\": \"integer\"\n },\n \"sizePerSec\": {\n \"description\": \"The average size of HTTP bodies per second in bytes\",\n \"type\": \"number\"\n }\n },\n \"required\": [\n \"successRate\",\n \"total\",\n \"slowest\",\n \"fastest\",\n \"average\",\n \"requestsPerSec\",\n \"totalData\",\n \"sizePerRequest\",\n \"sizePerSec\"\n ]\n },\n \"responseTimeHistogram\": {\n \"description\": \"The histogram of response time in seconds.
