Description

URL-prefix versioning layer that namespaces all public API endpoints under /api/v1/... to enable non-breaking evolution of the API contract over time. Ensures that the Flutter app can target a stable versioned API while the backend evolves and future versions can be introduced without disrupting existing clients.

Feature: REST API Backend

Responsibilities

  • Namespace all mobile-facing endpoints under /api/v1/ prefix
  • Support routing to future /api/v2/ or later versions without conflict
  • Maintain backward-compatible contracts for active client versions
  • Document version lifecycle and deprecation headers
  • Enforce version consistency in all route handler registrations
