Introduction
Websockets are a powerful tool for real-time communication between clients and servers. They enable bi-directional communication between a client and a server, allowing for the exchange of data in real-time. npm i Websocket is a popular module on npm that allows developers to easily integrate websockets into their Node.js applications. In this article, we will explore the ins and outs of npm i Websocket, from installation to implementation.
What is npm i Websocket?
npm i Websocket is a Node.js module that allows developers to implement websockets in their applications. It is a simple and easy-to-use module that abstracts away the complexities of implementing websockets from scratch. With npm i Websocket, developers can quickly and easily add real-time communication to their applications.
Installation
The first step in using npm i Websocket is to install it. Installing npm i Websocket is as simple as running the following command:
npm install websocket
This will install the latest version of the npm i Websocket module in your Node.js project.
Creating a Websocket Server
The next step is to create a websocket server. To create a websocket server using npm i Websocket, you need to do the following:
- Load the npm i Websocket module:
- Create a HTTP server:
- Create a websocket server:
const WebSocket = require(‘websocket’).server;
const http = require(‘http’);
const server = http.createServer();
const wsServer = new WebSocket({
httpServer: server,
});
This will create a websocket server that listens for incoming connections on the specified HTTP server.
Handling Websocket Connections
Once you have created a websocket server, you need to handle incoming websocket connections. To handle incoming websocket connections, you need to do the following:
- Listen for incoming connections:
- Accept incoming connections:
- Handle incoming messages:
- Send messages back to clients:
wsServer.on(‘request’, function(request) {
const connection = request.accept(null, request.origin);
connection.on(‘message’, function(message) {
connection.sendUTF(‘Hello, world!’);
This will handle incoming websocket connections and send messages back to clients.
Why Use npm i Websocket?
There are several reasons why developers might choose to use npm i Websocket:
Real-time Communication
