How do I set up routing in a TypeScript Express application?

To set up routing in a TypeScript Express application, you first need to install Express and TypeScript. Then, create a basic server.

Can you show me a simple example of a route?

Sure! Here's a basic example:

import express from 'express';

const app = express();
const PORT = 3000;

app.get('/api', (req, res) => {
    res.send('Hello from the API!');
});

app.listen(PORT, () => {
    console.log(`Server is running on http://localhost:${PORT}`);
});

What if I want to create multiple routes?

You can create multiple routes by defining them with different paths. For example:

app.get('/api/users', (req, res) => {
    res.send('User list');
});

app.get('/api/products', (req, res) => {
    res.send('Product list');
});

How do I handle route parameters?

You can handle route parameters by using a colon in the route path. For example:

app.get('/api/users/:id', (req, res) => {
    const userId = req.params.id;
    res.send(`User ID: ${userId}`);
});
