An example of an AI chatbot conversation about error handling in Express applications.
How can I handle errors in my Express app?
You can use middleware to handle errors in your Express app. Would you like to see an example?
Yes, please provide an example of error handling middleware.
Here's a simple example:
app.use((err, req, res, next) => {
console.error(err.stack);
res.status(500).send('Something broke!');
});
This middleware logs the error and sends a 500 response.
What about handling 404 errors?
You can add a 404 handler like this:
app.use((req, res, next) => {
res.status(404).send('Sorry, not found!');
});
This should be placed after all your routes.
