Node.js Error Handling Best Practices

Proper error handling ensures stable and maintainable Node.js apps.

1. Try/Catch Blocks

try {
  const data = await fetchData();
} catch (error) {
  console.error(error);
}

2. Error Middleware

app.use((err, req, res, next) => {
  res.status(500).json({ message: err.message });
});

3. Logging

Use tools like Winston or Pino for structured logging.

Conclusion

Good error handling reduces crashes and simplifies debugging.
