Building a Real-Time Game with Node.js and Phaser

Building a real-time game is a challenging task, but with the right tools and framework, it can be a rewarding experience. In this article, we’ll explore how to build a real-time game using Node.js and Phaser.

What is Node.js and Phaser?

Node.js is a server-side JavaScript runtime environment that allows developers to build fast and scalable network applications. It provides a vast array of features, such as handling HTTP requests, file system access, and real-time communication.

Phaser, on the other hand, is an open-source HTML5 game development framework. It provides a powerful set of tools for creating games, including physics engines, input handling, animation, and more.

Combining Node.js and Phaser

To create a real-time game, we need to establish a connection between the server and the client. This connection will allow the client to receive updates in real-time from the server, allowing for a seamless and immersive gaming experience.

We can use the WebSocket protocol to establish this connection. WebSocket is a bidirectional communication protocol that enables real-time communication between the client and server.

To get started, we’ll need to install the following dependencies:

  • Node.js
  • Express.js
  • Socket.io
  • Phaser

Once we have our dependencies installed, we can start building our game. Here’s an example of how to set up a simple real-time game using Node.js and Phaser:

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

app.use(express.static(path.join(__dirname, 'public')));

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname, 'index.html'));

io.on('connection', (socket) => {
  console.log('New player connected');

  socket.on('disconnect', () => {
    console.log('Player disconnected');

server.listen(8080, () => {
  console.log('Server started on port 8080');

This code sets up a basic Express.js server that serves static files from a public directory. It also creates a WebSocket connection using Socket.io.

We can now create a Phaser game that connects to this server and receives updates in real-time. Here’s an example of how to create a basic Phaser game that connects to our server:

const config = {
  type: Phaser.AUTO,
  width: 800,
  height: 600,
  parent: 'game-container',
  scene: {
    preload: preload,
    create: create,
    update: update

const game = new Phaser.Game(config);
const socket = io('http://localhost:8080');

function preload() {
  // Load game assets

function create() {
  // Create game objects

function update() {
  // Update game objects based on server data

socket.on('connect', () => {
  console.log('Connected to server');

socket.on('disconnect', () => {
  console.log('Disconnected from server');

socket.on('gameData', (data) => {
  // Update game objects based on server data

This code creates a Phaser game with a scene that loads game assets, creates game objects, and updates them based on server data. It also creates a WebSocket connection using Socket.io and listens for updates from the server.


Building a real-time game using Node.js and Phaser is a challenging but rewarding experience. By leveraging the power of Node.js and the Phaser framework, developers can create immersive and engaging gaming experiences that keep players coming back for more.
