expressjsHow do I use Express.js to create a YouTube clone?
Using Express.js to create a YouTube clone involves creating a Node.js server that serves HTML and JavaScript files to the client. The server should also handle AJAX requests to an API endpoint which is used to interact with the data store.
The following example code creates a basic Express.js server that serves a HTML file with a / route:
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.sendFile('index.html', { root: __dirname });
});
app.listen(3000, () => {
console.log('Server started on port 3000');
});
Output example
Server started on port 3000
