Refactoring Roadmaps

Implementation Roadmap

Phase 1: Quick Wins (1-2 weeks) ✅ DONE

  • [x] Extract HTTP headers to constants ✅

  • [x] Fix import ordering ✅

  • [x] Remove unused imports ✅

  • [ ] Extract magic values to constants

  • [ ] Improve exception handling

Phase 2: Foundation (2-3 weeks)

  • [ ] Create specialized endpoint base classes

  • [ ] Implement configuration object

  • [ ] Extract sync/async duplication

  • [ ] Add error registry

Phase 3: Architecture (3-4 weeks)

  • [ ] Split ListGetEndpointMixin (SRP)

  • [ ] Implement dependency injection container

  • [ ] Refactor Form Designer integration

  • [ ] Add protocol-based interfaces

Phase 4: Polish (1-2 weeks)

  • [ ] Refactor complex functions

  • [ ] Comprehensive testing of refactored code

  • [ ] Update documentation

  • [ ] Performance benchmarking

Testing Strategy

For each refactoring: 1. Write characterization tests before changing code 2. Refactor incrementally - one change at a time 3. Run full test suite after each change 4. Check test coverage - maintain ≥90% 5. Performance test critical paths

Success Metrics

  • Code Duplication: Reduce from ~40% to <10% in endpoints

  • Test Coverage: Maintain ≥90%

  • Cyclomatic Complexity: Reduce functions >15 to <10

  • Documentation: 100% of public API documented

  • Performance: <5% overhead from refactoring
