# Build A Group-Chat App in 30 Lines Using Node.js
A simple and (hopefully) to-the-point tutorial to build your first group-chat application using Node.js in less than 30 lines of code.
## Running the program
Run the program by using
```shell
$ node index.js
```
================================================
FILE: index.js
================================================
const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http);
app.get('/', function(req, res) {
res.render('index.ejs');
});
io.sockets.on('connection', function(socket) {
socket.on('username', function(username) {
socket.username = username;
io.emit('is_online', '🔵 ' + socket.username + ' join the chat..');
});
socket.on('disconnect', function(username) {
io.emit('is_online', '🔴 ' + socket.username + ' left the chat..');
})
socket.on('chat_message', function(message) {
io.emit('chat_message', '' + socket.username + ': ' + message);
});
});
const server = http.listen(8080, function() {
console.log('listening on *:8080');
});
