How to Install Websocket: A Complete Guide

Websocket is a computer communication protocol that provides full-duplex communication channels over a single TCP connection. It is widely used in web applications to provide real-time communication between clients and servers. Installing websocket is not a difficult task, but it requires some technical knowledge. In this guide, we will explain how to install websocket on different platforms, including Windows, Linux, and macOS.

What is Websocket and Why it is Important?

Websocket is a protocol that enables bidirectional communication between clients and servers over a single TCP connection. It provides a persistent connection between the client and the server, which allows real-time data transfer without the need for continuous HTTP requests. Websocket is important because it enables web applications to provide real-time communication, which is essential for many applications such as online gaming, chat applications, and stock trading platforms.

How to Use Websocket in Your Web Application

After installing websocket, you can use it in your web application to provide real-time communication between clients and servers. Here are the steps to use websocket in your web application:

  1. Create a new websocket server using the following code:

    var WebSocketServer = require(‘websocket’).server;

    var http = require(‘http’);

    var server = http.createServer(function(request, response) {

    // process HTTP request. Since we’re writing just WebSockets

    // server we don’t have to implement anything.

    });

    server.listen(8080, function() { });

    wsServer = new WebSocketServer({

    httpServer: server

    });

  2. Create a new websocket client using the following code:

    var WebSocket = require(‘websocket’).client;

    var client = new WebSocket();

    client.connect(‘ws://localhost:8080/’, ‘echo-protocol’);

    client.on(‘connect’, function(connection) {

    // do something with the connection

    });
