expressjsHow do I use Express.js and TypeScript together?

Using Express.js and TypeScript together is a great way to create powerful and robust web applications. Here's an example of how to do it:

// app.ts
import express from 'express';

// Create an Express app
const app = express();

// Add middleware
app.use(express.json());

// Add routes
app.get('/', (req, res) => {
    res.send('Hello World!');
});

// Start the server
app.listen(3000, () => console.log('Server running on port 3000'));
