// Step 1: Import the 'http' module
const http = require('http');
// Step 2: Create a server using the http module
const server = http.createServer((req, res) => {
// Step 3: Set the response header with a status code of 200 and content type of 'text/plain'
res.writeHead(200, {'Content-Type': 'text/plain'});
// Step 4: Send a response message to the client
res.end('Hello, this is a simple Node.js server!\n');
});
// Step 5: Specify the port number on which the server will listen
const port = 3000;
// Step 6: Make the server listen on the specified port
server.listen(port, () => {
console.log(`Server listening on port ${port}`);
});
