Socket.io NodeJS and AngularJS clients demo

socket-test.js

//On instruction of how to debug if sockets are working or not. Please check here https://socket.io/docs/logging-and-debugging/

//NodeJS Side

const server = require('http').Server(app),
    io = require('socket.io')(server);

io.sockets.on('connection', function (socket) {
    socket.on('set', function (status, callback) {
        console.log(status);
        callback('ok');
    });
});

//Angular JS Side
//After you have bower installed the socket.io-client dependency. In your app.js, create a factory of socket methods.
app.factory('socket', function($rootScope) {
    // let socket = io.connect('https://api.example.com');  //in production
    const socket = io.connect('http://localhost:3040'); //in development
    return {
        on: function(eventName, callback) {
            socket.on(eventName, function() {
                var args = arguments;
                $rootScope.$apply(function() {
                    callback.apply(socket, args);
                });
            });
        },
        emit: function(eventName, data, callback) {
            socket.emit(eventName, data, function() {
                var args = arguments;
                $rootScope.$apply(function() {
                    if (callback) {
                        callback.apply(socket, args);
                    }
                });
            });
        }
    };
});

//Dependency inject this into any controller and type their.

 socket.emit('set', 'is_it_ok', function(response) {
    console.log(response);
 });
