When building APIs, managing different versions is critical for backward compatibility and feature updates. NestJS provides built-in support for API versioning, allowing developers to handle multiple versions of APIs gracefully.
This article explores API versioning in NestJS, its types, and how to implement them with examples.
Why API Versioning?
API versioning helps manage changes in your application without breaking functionality for existing clients. It ensures:
- Smooth transitions between versions.
- Backward compatibility for older API clients.
- Clear separation of new features or deprecations.
