Felipe Cardoso cc98a76e24 Add timeout cleanup to password reset confirm page and improve accessibility attributes 
- Added `useEffect` for proper timeout cleanup in `PasswordResetConfirmForm` to prevent memory leaks during unmount.
- Enhanced form accessibility by adding `aria-required` attributes to all required fields for better screen reader compatibility.
- Updated `IMPLEMENTATION_PLAN.md` to reflect completion of Password Reset Flow and associated quality metrics.

Frontend Implementation Plan: Next.js + FastAPI Template

Last Updated: October 31, 2025 Current Phase: Phase 1 COMPLETE ✅ | Ready for Phase 2 Overall Progress: 1 of 12 phases complete

Summary

Build a production-ready Next.js 15 frontend with full authentication, admin dashboard, user/organization management, and session tracking. The frontend integrates with the existing FastAPI backend using OpenAPI-generated clients, TanStack Query for state, Zustand for auth, and shadcn/ui components.

Target: 90%+ test coverage, comprehensive documentation, and robust foundations for enterprise projects.

Current State: Phase 1 infrastructure complete with 81.6% test coverage, 66 passing tests, zero TypeScript errors Target State: Complete template matching frontend-requirements.md with all 12 phases

Implementation Directives (MUST FOLLOW)

Documentation-First Approach

  • Phase 0 created /docs folder with all architecture, standards, and guides ✅
  • ALL subsequent phases MUST reference and follow patterns in /docs
  • If context is lost, /docs + this file + frontend-requirements.md are sufficient to resume

Quality Assurance Protocol

1. Per-Task Quality Standards (MANDATORY):

  • Quality over Speed: Each task developed carefully, no rushing
  • Review Cycles: Minimum 3 review-fix cycles per task before completion
  • Test Coverage: Maintain >80% coverage at all times
  • Test Pass Rate: 100% of tests MUST pass (no exceptions)
    • If tests fail, task is NOT complete
    • Failed tests = incomplete implementation
    • Do not proceed until all tests pass
  • Standards Compliance: Zero violations of /docs/CODING_STANDARDS.md

2. After Each Task:

  • All tests passing (100% pass rate)
  • Coverage >80% for new code
  • TypeScript: 0 errors
  • ESLint: 0 warnings
  • Self-review cycle 1: Code quality
  • Self-review cycle 2: Security & accessibility
  • Self-review cycle 3: Performance & standards compliance
  • Documentation updated
  • IMPLEMENTATION_PLAN.md status updated

3. After Each Phase: Launch multi-agent deep review to:

  • Verify phase objectives met
  • Check integration with previous phases
  • Identify critical issues requiring immediate fixes
  • Recommend improvements before proceeding
  • Update documentation if patterns evolved
  • Generate phase review report (e.g., PHASE_X_REVIEW.md)

4. Testing Requirements:

  • Write tests alongside feature code (not after)
  • Unit tests: All hooks, utilities, services
  • Component tests: All reusable components
  • Integration tests: All pages and flows
  • E2E tests: Critical user journeys (auth, admin CRUD)
  • Target: 90%+ coverage for template robustness
  • 100% pass rate required - no failing tests allowed
  • Use Jest + React Testing Library + Playwright

5. Context Preservation:

  • Update /docs with implementation decisions
  • Document deviations from requirements in ARCHITECTURE.md
  • Keep frontend-requirements.md updated if backend changes
  • Update THIS FILE after each phase with actual progress
  • Create phase review reports for historical reference

⚠️ Known Technical Debt

  1. Dual API Client Setup - Currently using BOTH:

    • ✅ Generated client (src/lib/api/generated/**) - Auto-generated from OpenAPI
    • ✅ Manual client (src/lib/api/client.ts) - Has token refresh interceptors
    • ✅ Wrapper (src/lib/api/client-config.ts) - Configures both
    • Status: Both working. Manual client handles auth flow, generated client has types
    • Next Step: Migrate token refresh logic to use generated client exclusively

  2. Old Implementation Files - Need cleanup:

    • Delete: src/stores/authStore.old.ts (if exists)

  3. API Client Regeneration - When backend changes:

    • Run: npm run generate:api (requires backend at http://localhost:8000)
    • Files regenerate: src/lib/api/generated/**
    • Wrapper client-config.ts is NOT overwritten (safe)

# Development
npm run dev                  # Start dev server (http://localhost:3000)
npm run build                # Production build
npm run start                # Start production server

# Testing
npm test                     # Run tests
npm test -- --coverage       # Run tests with coverage report
npm run type-check           # TypeScript compilation check
npm run lint                 # ESLint check

# API Client Generation (needs backend running)
npm run generate:api         # Generate TypeScript client from OpenAPI spec

# Package Management
npm install                  # Install dependencies
npm audit                    # Check for vulnerabilities

Environment Variables

Required:

Current Technical State

What Works:

  • ✅ Authentication core (crypto, storage, store)
  • ✅ Configuration management
  • ✅ Test infrastructure
  • ✅ TypeScript compilation
  • ✅ Development environment

What's Needed Next:

  • Generate API client from backend
  • Build auth UI (login, register, password reset)
  • Implement auth pages
  • Add E2E tests for auth flows

Technical Debt:

  • Manual API client files (will be replaced)
  • Old implementation files (need cleanup)
  • No API generation yet (needs backend)

Notes for Future Development

When Starting Phase 2

  1. Generate API client first:

    # Ensure backend is running
cd ../backend && uvicorn app.main:app --reload

# In separate terminal
cd frontend
npm run generate:api

  2. Review generated types in src/lib/api/generated/

  3. Replace manual client files:

    • Archive or delete src/lib/api/client.ts
    • Archive or delete src/lib/api/errors.ts
    • Create thin wrapper if interceptor logic needed

  4. Follow patterns in docs/FEATURE_EXAMPLES.md

  5. Write tests alongside code (not after)

Remember

  • Documentation First: Check docs before implementing
  • Test As You Go: Don't batch testing at end
  • Review Often: Self-review after each task
  • Update This Plan: Keep it current with actual progress
  • Context Matters: This file + docs = full context
