How can I handle database errors in my Express app?

You can handle database errors in your Express app by using middleware to catch errors and send appropriate responses.

Can you show me an example of error handling middleware?

Sure! Here's a simple example:

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

What if I want to handle different types of database errors?

You can check the error type in your middleware and respond accordingly. For example, you might want to handle validation errors differently.

How can I log these errors for later analysis?

You can use a logging library like Winston or Morgan to log errors to a file or external service for later analysis.
