NestJS in Production: Best Practices for Reliability

Why NestJS Developers Need This

Building reliable NestJS applications requires more than just writing code. You need proper error handling, monitoring, and debugging practices to ship with confidence.

The Basics

Every NestJS application should have:

1. Error handling at every boundary (API calls, user input, file I/O)
2. Error tracking to catch bugs in production automatically
3. Logging for debugging and audit trails
4. Monitoring for performance and availability
