How can I debug async errors in my Express app?

You can use middleware to catch async errors. Try wrapping your async route handlers in a try-catch block.

What if I want to handle errors globally?

You can create a global error handling middleware. Just define a function that takes four parameters: err, req, res, next.

Can you show me an example of global error handling?

Sure! Here's a simple example:

app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).send('Something broke!');
});

What about logging the errors?

You can use libraries like Winston or Morgan to log errors effectively. They provide more control over logging.
