How can I implement async routes in TypeScript with Express?

You can use async/await syntax in your route handlers. Here's a simple example:

import express from 'express';

const app = express();

app.get('/data', async (req, res) => {
    try {
        const data = await fetchData(); // Assume fetchData is an async function
        res.json(data);
    } catch (error) {
        res.status(500).send('Error fetching data');
    }
});

What if I want to handle multiple async routes?

You can define multiple routes using the same async pattern. Just ensure each route has its own try/catch block for error handling.

Can I use middleware with async routes?

Yes, you can use async middleware as well. Just remember to handle errors properly, either with a try/catch or by passing errors to the next function.

What are some common pitfalls when using async/await in Express?

Common pitfalls include forgetting to handle errors, not returning promises in middleware, and mixing async/await with callbacks.
