This module allows the Vert.x users can make a socket.io server as node.js users do. Now, This module supports the latest version of the socket.io, 0.9.10.
The module name is socket-io.
Add a maven repository contains mod-socket-io.

You can configure everything that you can configure in the Socket.io like:
io.configure(new Configurer() {
public void configure(JsonObject config) {
config.putString("transports", "websocket,flashsocket,htmlfile,xhr-polling,jsonp-polling");
config.putBoolean("authorization", true);
}
});You can use this module in a simple Verticle like:
import com.nhncorp.mods.socket.io.SocketIOServer;
import com.nhncorp.mods.socket.io.SocketIOSocket;
import com.nhncorp.mods.socket.io.impl.DefaultSocketIOServer;
import org.vertx.java.core.Handler;
import org.vertx.java.core.http.HttpServer;
import org.vertx.java.core.json.JsonObject;
import org.vertx.java.deploy.Verticle;

public class SampleVerticle extends Verticle {
@Override
public void start() throws Exception {
int port = 9090;
HttpServer server = vertx.createHttpServer();
SocketIOServer io = new DefaultSocketIOServer(vertx, server);
io.sockets().onConnection(new Handler<SocketIOSocket>() {
public void handle(final SocketIOSocket socket) {
socket.on("timer", new Handler<JsonObject>() {
public void handle(JsonObject event) {
socket.emit("timer", event);
}
});
}
});
System.out.println("server is running on http://localshot:" + port);
server.listen(port);
}
}The code is located in samples/verticle/SampleVerticle.java.
You can run this module by vertx run but before run this simple verticle, you should put some jars to the classpath.
Here is some options you can use.
- simply add all files in the
distdirectory to yourVERTX_HOME/libsdirectory - or use
-cpoption when you run the verticle.
Now, you can run the verticle like:
samples/verticle> vertx run SampleVerticle.java
First, you should include this module's resource by includes:.
{
"main": "package.to.your.RunnableClassName",
"includes": "com.nhncorp.socket-io-v0.9.10"
}
And, after you put the module's jar file to you module's classpath. You can code like:
public class RunnableClassName extends Verticle {
@Override
public void start() {
HttpServer server = vertx.createHttpServer();
SocketIOServer io = new DefaultSocketIOServer(vertx, server);
io.sockets().onConnection(new Handler<SocketIOSocket>() {
public void handle(final SocketIOSocket socket) {
JsonObject data = new JsonObject();
data.putString("hello", "world");
socket.emit("news", data);
socket.on("my other event", new Handler<JsonObject>() {
public void handle(JsonObject data) {
System.out.println(data);
}
});
}
});
server.listen(9090);
}
}In the view, you can use the same socket.io javascript like:
<script type="text/javascript" src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:9090');
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
</script>
