In today’s digital world, users expect real-time interactions — whether it’s live chat, notifications, or dynamic collaboration tools. WebSockets make this possible by enabling two-way communication between the server and the browser. At Sternhost, setting up a WebSocket server is fast, flexible, and beginner-friendly. Here’s how you can do it!

Why Use WebSockets for Your Chat App?

Traditional HTTP is request-response based — your browser asks for something, the server responds. But WebSockets create a persistent connection, allowing continuous data flow without repeated requests. This makes your chat apps ultra-responsive, efficient, and smooth.

Benefits of WebSockets:

• Instant messaging and updates.
• Lower latency compared to polling methods.
• Reduces server load.
• Enables real-time gaming, trading, collaboration, and more.

Setting Up a WebSocket Server on Sternhost

Sternhost’s VPS Hosting gives you full control to install Node.js, Python, or any server technology you prefer. Here’s a simple guide to launch your WebSocket project:

1. Choose a VPS Hosting Plan

First, make sure you’re on a VPS Hosting plan from Sternhost. Explore Sternhost VPS Plans here.

Our plans are affordable and scalable, perfect for growing your real-time application.

2. Install Node.js or Python

Once your VPS is ready:

• Access your VPS via SSH.
• For Node.js, install it with:

  sudo apt update
  sudo apt install nodejs npm
  

• For Python, install if not already available:

  sudo apt install python3 python3-pip
  

3. Build Your WebSocket Server

Example for Node.js (using ws package):

const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', function connection(ws) {
  ws.on('message', function incoming(message) {
    console.log('received: %s', message);
  });
  ws.send('Hello! Message from Sternhost WebSocket Server');
});

Install ws package:

npm install ws

Example for Python (using websockets library):

import asyncio
import websockets

async def echo(websocket, path):
    async for message in websocket:
        await websocket.send(f"Echo: {message}")

start_server = websockets.serve(echo, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

Install websockets package:

pip3 install websockets

4. Point Your Domain to Your WebSocket Server

• Go to your Sternhost Control Panel.
• Update your domain’s A Record to point to your VPS IP address.
• If needed, set up an SSL certificate for secure wss:// connections. Learn how to install SSL with Sternhost.

5. Run Your Server in the Background

Use pm2 for Node.js apps:

npm install pm2 -g
pm2 start app.js
pm2 startup
pm2 save

Or use screen/tmux sessions to keep Python servers running.
