How can I handle errors in Node.js microservices?

In Node.js microservices, you can handle errors using middleware, try-catch blocks, and centralized error handling.

What are some common error handling patterns?

Common patterns include using async/await with try-catch, event emitters for error events, and returning standardized error responses.

How do I implement centralized error handling?

You can create a custom error handling middleware that catches errors from all routes and formats the response.

Can you give an example of a centralized error handler?

Sure! Here's a simple example:

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