Reactive Extension (Rx) Adaptor for Netty

RxNetty

Reactive Extension (Rx) Adaptor for Netty

Getting Started

The best place to start exploring this library is to look at the class [RxNetty] (rxnetty/src/main/java/io/reactivex/netty/RxNetty.java)

You can also find some common examples of clients and servers created using RxNetty in the [examples directory] (rxnetty-examples)

A very simple HTTP server example can be found [here] (rxnetty-examples/src/main/java/io/reactivex/netty/examples/http/helloworld/HelloWorldServer.java) and the corresponding HTTP client is [here] (rxnetty-examples/src/test/java/io/reactivex/netty/examples/http/helloworld/HelloWorldTest.java)

Example

import io.netty.buffer.ByteBuf;
import io.netty.handler.codec.http.HttpResponseStatus;
import io.reactivex.netty.RxNetty;
import io.reactivex.netty.protocol.http.server.HttpServer;

import java.nio.charset.Charset;

public final class RxNettyExample {

    public static void main(String... args) throws InterruptedException {
        HttpServer<ByteBuf, ByteBuf> server = RxNetty.createHttpServer(8080, (request, response) -> {
            System.out.println("Server => Request: " + request.getPath());
            try {
                if ("/error".equals(request.getPath())) {
                    throw new RuntimeException("forced error");
                }
                response.setStatus(HttpResponseStatus.OK);
                response.writeString("Path Requested =>: " + request.getPath() + '\n');
                return response.close();
            } catch (Throwable e) {
                System.err.println("Server => Error [" + request.getPath() + "] => " + e);
                response.setStatus(HttpResponseStatus.BAD_REQUEST);
                response.writeString("Error 500: Bad Request\n");
                return response.close();
            }
        });

        server.start();

        RxNetty.createHttpGet("http://localhost:8080/")
               .flatMap(response -> response.getContent())
               .map(data -> "Client => " + data.toString(Charset.defaultCharset()))
               .toBlocking().forEach(System.out::println);

        RxNetty.createHttpGet("http://localhost:8080/error")
               .flatMap(response -> response.getContent())
               .map(data -> "Client => " + data.toString(Charset.defaultCharset()))
               .toBlocking().forEach(System.out::println);

        RxNetty.createHttpGet("http://localhost:8080/data")
               .flatMap(response -> response.getContent())
               .map(data -> "Client => " + data.toString(Charset.defaultCharset()))
               .toBlocking().forEach(System.out::println);

        server.shutdown();
    }
}

Outputs:

Server => Request: /
Client => Path Requested =>: /

Server => Request: /error
Server => Error [/error] => java.lang.RuntimeException: forced error
Client => Error 500: Bad Request

Server => Request: /data
Client => Path Requested =>: /data
