Error Handling in Express

Error handling is critical in Express apps to ensure graceful failure and proper debugging.

  • Use next(err) to pass errors to middleware
  • Define a centralized error handler at the end
  • Log and respond with appropriate status codes
app.use((err, req, res, next) => {
  res.status(500).json({ error: err.message });
});
