Kotlin Socket.IO example connection function.

Kotlin Socket.IO example

import io.socket.client.IO
import io.socket.client.Socket

fun connect() {
  val socket = IO.socket("http://localhost:4000?user=aksel")
  socket.connect()
        .on(Socket.EVENT_CONNECT, { println("connected") })
        .on(Socket.EVENT_DISCONNECT, { println("disconnected") })
}

This gist is an example connect function.
It connects to a socketio server, hosted at localhost, on port 4000.
It passes a username "aksel" in the queryparams.

An equivalent Javascript socket connection would look something like this:

const socket = io({ query: { user: 'aksel' } });
socket.on('connect', () => console.log('connected'));
socket.on('disconnect', () => console.log('disconnected'));

import com.github.nkzawa.socketio.client.IO
import com.github.nkzawa.socketio.client.Socket

And @aksel with Ack() ?

java code

sockets.mSocket.emit("socketID", data, new Ack() {
    @Override
    public void call(Object... args) {
        JSONObject repues = (JSONObject) args[0];
        // todo with repues
    }
});

Javascript code

sockets.emit("socketID", data, repues=>{
    // todo with repues
});

What if i wanna access socket in multiple kt files or activities in android?

cool, man @aksel , thanks, please to check your gradle file.
