In order to do it, you need to create an index. js file and install socket.io and express. You can use the following command: touch index. js && npm install express socket.io && npm install --save-dev nodemon .
listen(port); // Create a Socket.IO instance, passing it our server var socket = io. listen(server); // Add a connect listener socket. on('connection', function(client){ console. log('Connection to client established'); // Success!
In this guide we'll create a basic chat application. It requires almost no basic prior knowledge of Node. JS or Socket.IO, so it's ideal for users of all knowledge levels.
That should be possible using Socket.IO-client: https://github.com/LearnBoost/socket.io-client
Adding in example for solution given earlier. By using socket.io-client
https://github.com/socketio/socket.io-client
Client Side:
//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});
// Add a connect listener
socket.on('connect', function (socket) {
console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');
Server Side :
//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
io.on('connection', function (socket){
console.log('connection');
socket.on('CH01', function (from, msg) {
console.log('MSG', from, ' saying ', msg);
});
});
http.listen(3000, function () {
console.log('listening on *:3000');
});
Run :
Open 2 console and run node server.js
and node client.js
After installing socket.io-client:
npm install socket.io-client
This is how the client code looks like:
var io = require('socket.io-client'),
socket = io.connect('http://localhost', {
port: 1337,
reconnect: true
});
socket.on('connect', function () { console.log("socket connected"); });
socket.emit('private message', { user: 'me', msg: 'whazzzup?' });
