how to run express server in terminal code example
Example 1: Create a server which serves at port 3000 and with node.js command prompt
// app.js
const http = require('http');
// Create an instance of the http server to handle HTTP requests
let app = http.createServer((req, res) => {
// Set a response type of plain text for the response
res.writeHead(200, {'Content-Type': 'text/plain'});
// Send back a response and end the connection
res.end('Hello World!\n');
});
// Start the server on port 3000
app.listen(3000, '127.0.0.1');
console.log('Node server running on port 3000');
