Node.js is an open-source JavaScript runtime environment. Below is the basic code to print "Hello, World!" in Node.js or run a very basic server. We are using the HTTP module to create a server with the Content-Type "text/html" on port 3000. You can access it at 127.0.0.1:3000 after running the command "node your-file.js". If you haven't installed Node.js yet, you can do so from here:
Install Node JS, and with the copy of the below code you can run your first Node.js Server if you haven't done this yet.
const { createServer } = require('node:http');
const hostname = '127.0.0.1';
const port = 3000;
const server = createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
