base on TCP/HTTP/UDP/QUIC client/server with Reactor over Netty # Reactor Netty [](https://gitter.im/reactor/reactor-netty) [](https://mvnrepository.com/artifact/io.projectreactor.netty/reactor-netty) [](https://github.com/reactor/reactor-netty/actions/workflows/publish.yml) [](https://github.com/reactor/reactor-netty/actions?query=workflow%3ACodeQL) `Reactor Netty` offers non-blocking and backpressure-ready `TCP`/`HTTP`/`UDP`/`QUIC` clients & servers based on `Netty` framework. ## Getting it `Reactor Netty` requires Java 8 or + to run. With `Gradle` from [repo.spring.io](https://repo.spring.io) or `Maven Central` repositories (stable releases only): ```groovy repositories { //maven { url 'https://repo.spring.io/snapshot' } maven { url 'https://repo.spring.io/milestone' } mavenCentral() } dependencies { //compile "io.projectreactor.netty:reactor-netty-core:1.2.2-SNAPSHOT" compile "io.projectreactor.netty:reactor-netty-core:1.2.1" //compile "io.projectreactor.netty:reactor-netty-http:1.2.2-SNAPSHOT" compile "io.projectreactor.netty:reactor-netty-http:1.2.1" } ``` See the [Reference documentation](https://projectreactor.io/docs/netty/release/reference/index.html#getting) for more information on getting it (eg. using `Maven`, or on how to get milestones and snapshots). ## Getting Started New to `Reactor Netty`? Check this [Reactor Netty Workshop](https://violetagg.github.io/reactor-netty-workshop/) and the [Reference documentation](https://projectreactor.io/docs/netty/release/reference/index.html) Here is a very simple `HTTP` server and the corresponding `HTTP` client example ```java HttpServer.create() // Prepares an HTTP server ready for configuration .port(0) // Configures the port number as zero, this will let the system pick up // an ephemeral port when binding the server .route(routes -> // The server will respond only on POST requests // where the path starts with /test and then there is path parameter routes.post("/test/{param}", (request, response) -> response.sendString(request.receive() .asString() .map(s -> s + ' ' + request.param("param") + '!') .log("http-server")))) .bindNow(); // Starts the server in a blocking fashion, and waits for it to finish its initialization ``` ```java HttpClient.create() // Prepares an HTTP client ready for configuration .port(server.port()) // Obtains the server's port and provides it as a port to which this // client should connect .post() // Specifies that POST method will be used .uri("/test/World") // Specifies the path .send(ByteBufFlux.fromString(Flux.just("Hello"))) // Sends the request body .responseContent() // Receives the response body .aggregate() .asString() .log("http-client") .block(); ``` ## Getting help Having trouble with `Reactor Netty`?
