Integrating WebSocket with Other Technologies in Node.js

When building real-time applications, integrating WebSocket with other technologies not only adds flexibility but also opens up new possibilities for development. In this article, we'll delve deeper into how to integrate WebSocket with several popular technologies within the Node.js environment.

Integration with Express and HTTP Server

When you want to integrate WebSocket with an existing HTTP server, using the Express framework along with the WebSocket library (ws) is a solid choice. The following example illustrates how to combine them:

const express = require('express');
const http = require('http');
const WebSocket = require('ws');

const app = express();
const server = http.createServer(app);
const wss = new WebSocket.Server({ server });

app.get('/', (req, res) => {
    // Handle HTTP requests

wss.on('connection', (socket) => {
    // Handle WebSocket connection

Integration with RESTful APIs

When you need to combine the real-time communication capability of WebSocket with communication via RESTful APIs, you can integrate both to leverage the benefits of both approaches. When a significant event occurs on the WebSocket server, you can notify the RESTful API server to update data.

Integration with Databases

In the context of real-time application development, integrating WebSocket with a database is crucial. Through WebSocket events, you can update real-time data in the database and inform client connections about these changes.

Integration with Angular or React

If you're using frameworks like Angular or React to build user interfaces, integrating WebSocket is a powerful way to update data without requiring page reloads. Libraries such as ngx-socket-io for Angular or for React are great choices for integrating WebSocket into your application.


Integrating WebSocket with other technologies in Node.js is a vital step in constructing diverse and feature-rich real-time applications. By harnessing the power of integration, you can create interactive applications tailored to your preferences.
