# Frontend Implementation Plan: Next.js + FastAPI Template **Last Updated:** November 7, 2025 (Phase 9 COMPLETE ✅) **Current Phase:** Phase 9 COMPLETE ✅ | Next: Phase 10 (Testing & QA) **Overall Progress:** 9 of 13 phases complete (69.2%) --- ## 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:** Phases 0-9 complete with 954 unit tests (100% pass rate), 95.6% coverage, 173+ E2E tests, zero build/lint/type errors ⭐ **Target State:** Complete template matching `frontend-requirements.md` with all 13 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 --- ## Current System State (Phase 1 Complete) ### ✅ What's Implemented **Project Infrastructure:** - Next.js 15 with App Router - TypeScript strict mode enabled -
