Socket.io-PingPong

Shortcut to on and emit. Pingpong as you receive the event and returns in the same role.

Reason:

With socket "emit" I requested and received the data and then to "emit". I decided to reduce the process by creating the PingPong

Install

npm install --save socket.io-pingpong

Features

You can use ping pong or pp to call the methods

• emit(name, args, callback) Same socket.emit, but returns a given value on the server callback
• on(name, callback) socket.on the same as, but performs emit passing to the callback

Example

server.js

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var pingpong = require('socket.io-pingpong');

server.listen(8888); // you port

app.use(pingpong());

io.on('connection', function(socket) {
    var socket = pingpong(socket);

    socket.pp.on('name', function(value) {
        return value + " Assis";
    })

    socket.pp.emit('age', 27, function(age) {
        console.log('age:', age);
    })

});
