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);
})
});
