An example of an AI chatbot conversation about logging errors in Express.js.
How do I log errors in Express.js?
You can log errors in Express.js using middleware. Would you like to see an example?
Yes, please provide an example of error logging.
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 stack to the console.
Can I log errors to a file instead of the console?
Absolutely! You can use libraries like winston or morgan to log errors to a file. Would you like to know how to set that up?
