Node.js Net

Node.js provides the ability to perform socket programming. We can create chat application or communicate client and server applications using socket programming in Node.js. The Node.js net module contains functions for creating both servers and clients.

Node.js Net Example

In this example, we are using two command prompts:

Node.js command prompt for server.
Window’s default command prompt for client.

server:

File: net_server.js

 const net = require(‘net’); var server = net.createServer((socket) => {   socket.end(‘goodbyen’); }).on(‘error’, (err) => {   // handle errors here   throw err; }); // grab a random port. server.listen(() => {   address = server.address();   console.log(‘opened server on %j’, address); }); 

Open Node.js command prompt and run the following code:

client:

File: net_client.js

 const net = require(‘net’); const client = net.connect({port: 50302}, () => {//use same port of server   console.log(‘connected to server!’);   client.write(‘world!rn’); }); client.on(‘data’, (data) => {   console.log(data.toString());   client.end(); }); client.on(‘end’, () => {   console.log(‘disconnected from server’); }); 

Open Node.js command prompt and run the following code:

Note: You must match the port. The client and server should have similar port for successful connection.
