All development will be conducted in Playtika fork https://github.com/Playtika/feign-reactive\n\n[Subscribe to stay up to date 🙂](https://www.youtube.com/channel/UCAIRpdkVAj1RT6butHUV9yg)\n\n# feign-reactive\n\n[ ![Download](https://api.bintray.com/packages/kptfh/feign-reactive/client/images/download.svg) ](https://bintray.com/kptfh/feign-reactive/client/_latestVersion)\n\nUse Feign with Spring WebFlux\n\n## Overview\n\nImplementation of Feign on Spring WebClient. Brings you the best of two worlds together : \nconcise syntax of Feign to write client side API on fast, asynchronous and\nnon-blocking HTTP client of Spring WebClient.\n\n## Modules\n \n **_feign-reactor-core_** : base classes and interfaces that should allow to implement alternative reactor Feign\n \n **_feign-reactor-webclient_** : Spring WebClient based implementation of reactor Feign \n \n **_feign-reactor-cloud_** : Spring Cloud implementation of reactor Feign (Ribbon/Hystrix)\n \n **_feign-reactor-rx2_** : Rx2 compatible implementation of reactor Feign (depends on feign-reactor-webclient)\n \n **_feign-reactor-jetty_** : experimental Reactive Jetty client based implementation of reactor Feign (doesn't depend on feign-reactor-webclient). In future will allow to write pure Rx2 version.\n - have greater reactivity level then Spring WebClient. By default don't collect body to list instead starts sending request body as stream. \n - starts receiving reactive response before all reactive request body has been sent\n - process Flux<`String`> correctly in request and response body \n\n## Usage\n\nWrite Feign API as usual, but every method of interface\n - may accept `org.reactivestreams.Publisher` as body\n - must return `reactor.core.publisher.Mono` or `reactor.core.publisher.Flux`.\n\n```java\n@Headers({ \"Accept: application/json\" })\npublic interface IcecreamServiceApi {\n\n @RequestLine(\"GET /icecream/flavors\")\n Flux getAvailableFlavors();\n\n @RequestLine(\"GET /icecream/mixins\")\n Flux getAvailableMixins();\n\n @RequestLine(\"POST /icecream/orders\")\n @Headers(\"Content-Type: application/json\")\n Mono makeOrder(IceCreamOrder order);\n\n @RequestLine(\"GET /icecream/orders/{orderId}\")\n Mono findOrder(@Param(\"orderId\") int orderId);\n\n @RequestLine(\"POST /icecream/bills/pay\")\n @Headers(\"Content-Type: application/json\")\n Mono payBill(Publisher bill);\n}\n```\nBuild the client :\n\n```java\n\n/* Create instance of your API */\nIcecreamServiceApi client = ReactiveFeign\n .builder()\n .target(IcecreamServiceApi.class, \"http://www.icecreame.com\")\n\n/* Execute nonblocking requests */\nFlux flavors = icecreamApi.getAvailableFlavors();\nFlux mixins = icecreamApi.getAvailableMixins();\n```\n\nor cloud aware client :\n\n```java\n IcecreamServiceApi client = CloudReactiveFeign.builder()\n .setFallback(new TestInterface() {\n @Override\n public Mono get() {\n return Mono.just(\"fallback\");\n }\n })\n .setLoadBalancerCommand(\n LoadBalancerCommand.builder()\n .withLoadBalancer(AbstractLoadBalancer.class.cast(getNamedLoadBalancer(serviceName)))\n .withRetryHandler(new DefaultLoadBalancerRetryHandler(1, 1, true))\n .build()\n )\n .target(IcecreamServiceApi.class, \"http://\" + serviceName);\n\n/* Execute nonblocking requests */\nFlux flavors = icecreamApi.getAvailableFlavors();\nFlux mixins = icecreamApi.getAvailableMixins();\n```\n\n## Rx2 Usage \n\nWrite Feign API as usual, but every method of interface\n - may accept `Flowable`, `Observable`, `Single` or `Maybe` as body\n - must return `Flowable`, `Observable`, `Single` or `Maybe`.\n\n```java\n@Headers({\"Accept: application/json\"})\npublic interface IcecreamServiceApi {\n\n @RequestLine(\"GET /icecream/flavors\")\n Flowable getAvailableFlavors();\n\n @RequestLine(\"GET /icecream/mixins\")\n Observable getAvailableMixins();\n\n @RequestLine(\"POST /icecream/orders\")\n @Headers(\"Content-Type: application/json\")\n Single makeOrder(IceCreamOrder order);\n\n @RequestLine(\"GET /icecream/orders/{orderId}\")\n Maybe findOrder(@Param(\"orderId\") int orderId);\n\n @RequestLine(\"POST /icecream/bills/pay\")\n @Headers(\"Content-Type: application/json\")\n Single payBill(Bill bill);\n```\nBuild the client :\n\n```java\n\n/* Create instance of your API */\nIcecreamServiceApi client = Rx2ReactiveFeign\n .builder()\n .target(IcecreamServiceApi.class, \"http://www.icecreame.com\")\n\n/* Execute nonblocking requests */\nFlowable flavors = icecreamApi.getAvailableFlavors();\nObservable mixins = icecreamApi.getAvailableMixins();\n```\n\n## Maven\n\n```xml\n\n \n bintray-kptfh-feign-reactive\n bintray\n https://dl.bintray.com/kptfh/feign-reactive\n \n\n...\n\n ...\n \n \n
