🔢 API Versioning Toolkit

$4.99

Evolve your API without breaking existing clients. This toolkit provides URL-based versioning (/v1/, /v2/), Accept-header versioning, and a deprecation notice system that warns clients before removing old endpoints. Includes a version registry, route aliasing, and sunset headers — all in plain Python stdlib.

What’s Included

  • ✓ Versioning middleware (~160 lines, stdlib only)
  • ✓ URL prefix versioning: /v1/, /v2/, /latest/
  • ✓ Accept-header versioning (application/vnd.api+json; version=2)
  • ✓ Deprecation-Date and Sunset headers per RFC 8594
  • ✓ Version registry with rollout and sunset date tracking
  • ✓ Route aliasing so v1 and v2 share handlers where unchanged
  • ✓ Example showing a v1-to-v2 migration with backward compat
  • ✓ MIT License — use in commercial projects
