How do I start with Node.js after I installed it?
Once you have installed Node, let's try building our first web server. Create a file named "app.js", and paste the following code:
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
After that, run your web server using node app.js
, visit http://localhost:3000
, and you will see a message 'Hello World'
