From c64cdcd9e37a62e81af051840f2dd3138cc673f3 Mon Sep 17 00:00:00 2001 From: LaurensBartelds Date: Sun, 26 Apr 2026 20:10:46 +0200 Subject: [PATCH 01/16] feat: Implement API modules for admin, auth, exam, result, and setup functionalities - Created adminApi.ts for admin-related operations including user management and site settings. - Developed authApi.ts for authentication processes such as registration, login, and profile management. - Added examApi.ts for handling exam CRUD operations. - Introduced resultApi.ts for managing results submission and retrieval. - Established setupApi.ts for initial setup processes and status checks. - Created ErrorBoundary component to handle rendering errors gracefully in the frontend. - Re-exported shared API utilities in index.ts for easier access. --- backend/src/config.ts | 48 +++ backend/src/db/database.ts | 7 +- backend/src/index.ts | 45 ++- backend/src/middleware/auth.ts | 4 + backend/src/middleware/error.ts | 30 ++

All TypeScript compilation verified. +> **Date**: 2026-04-26 + +--- + +## Executive Summary + +This plan documents all changes made and remaining work needed to make BrainWave ready for future expansion. The core principle is **layered architecture**: separating data access, business logic, API routes, and frontend concerns into independent, testable layers. + +--- + +## ✅ Completed (Phase 1 — Foundation + Phase 2 — Consolidation) + +### 1. Backend: Repository Layer + +**Problem**: Routes had direct SQL/DB access mixed with business logic. + +**Solution**: Created pure data access modules: + +| Repository | File | Responsibility | +| -------------- | ------------------------------------------ | ------------------------------- | +| `userRepo` | `backend/src/repositories/userRepo.ts` | Users CRUD, counting, searching | +| `examRepo` | `backend/src/repositories/examRepo.ts` | Exams CRUD, listing by user | +| `resultRepo` | `backend/src/repositories/resultRepo.ts` | Results CRUD, statistics | +| `settingsRepo` | `backend/src/repositories/settingsRepo.ts` | Key-value settings | + +**Why**: Lets you swap SQLite for PostgreSQL later by only touching 4 files. No route or service changes needed. + +### 2. Backend: Zod Validation + Middleware + +**Problem**: No input validation. Manual type checking in every route. + +**Solution**: Created schema-per-domain: + +- `authSchemas.ts` — register, login, profile, password, email verification, reset +- `examSchemas.ts` — save, update, id param +- `resultSchemas.ts` — submit, id param +- `adminSchemas.ts` — role update, settings, user list queries +- `setupSchemas.ts` — wizard setup + +**Middleware**: `validateBody()`, `validateParams()`, `validateQuery()` — generic wrappers that parse with Zod and attach `req.parsedBody`/`req.parsedQuery`. + +**Why**: Defensive coding. Prevents injection, malformed data, and gives typed request bodies. + +### 3. Backend: Centralized Error Handling + +**Problem**: try/catch in every async route handler, inconsistent error responses. + +**Solution**: + +- `AppError` class with status codes +- `asyncHandler()` wrapper — catches async errors, forwards to error handler +- `errorHandler` middleware — consistent JSON error format + +**Why**: No more try/catch boilerplate. All errors flow through one path. + +### 4. Backend: Service Layer (Auth) + +**Problem**: Auth business logic (registration, login, email flow) was inline in routes. + +**Solution**: `backend/src/services/authService.ts` — pure business logic, no HTTP concerns. + +**Why**: Business rules can be unit tested without spinning up Express. Enables sharing logic between REST and future GraphQL/WebSocket APIs. + +### 5. Backend: Route Refactoring + +All routes now follow the same pattern: + +``` +middleware → validateInput → asyncHandler(serviceCall) → errorHandler +``` + +| Route | Status | +| ------------ | -------------------------------------------------------- | +| `auth.ts` | ✅ Full refactor (services + validation + rate limiting) | +| `exams.ts` | ✅ Refactored (repo + validation + asyncHandler) | +| `results.ts` | ✅ Refactored (repo + validation + asyncHandler) | +| `admin.ts` | ✅ Refactored (repo + validation + asyncHandler) | +| `setup.ts` | ✅ Refactored (repo + validation + asyncHandler) | + +### 6. Backend: Security Hardening + +- **Rate limiting** on auth endpoints (10 req/15min window) +- **JWT secret validation** — app exits with clear error if `JWT_SECRET` missing +- **Request logging** — `METHOD PATH STATUS - DURATIONms` + +### 7. Frontend: API Abstraction Layer + +**Problem**: Raw `apiFetch()` calls scattered across components. Hard to change endpoints or add caching. + +**Solution**: Domain-specific API modules: + +| Module | File | Covers | +| ----------- | ------------------------------- | ---------------------------------- | +| `authApi` | `frontend/src/api/authApi.ts` | Login, register, profile, password | +| `examApi` | `frontend/src/api/examApi.ts` | CRUD for exams | +| `resultApi` | `frontend/src/api/resultApi.ts` | List, get, submit, delete results | +| `adminApi` | `frontend/src/api/adminApi.ts` | Users, stats, settings | +| `setupApi` | `frontend/src/api/setupApi.ts` | Setup wizard | + +**Updated components**: ALL components now import from API modules: + +- `AuthContext` — uses `authApi` + `setupApi` +- `MyExams` — uses `examApi` +- `MyResults` — uses `resultApi` +- `ExamEditor` — uses `examApi` +- `Settings` — uses `authApi` +- `AdminDashboard` — uses `adminApi` +- `SetupWizard` — uses `setupApi` +- `ExamRunner` — uses `resultApi` +- `Workspace` — uses `authApi` + +Zero `apiFetch()` calls remain in any `.tsx` file. + +**Why**: One place to add request deduplication, caching, or optimistic updates. Also makes mocking for tests trivial. + +### 8. Frontend: React Error Boundaries + +**Problem**: Any rendering error crashes the entire app (white screen). + +**Solution**: `frontend/src/components/ErrorBoundary.tsx` — class component with fallback UI showing error message and reload button. + +**Integration**: Wrapped the entire `` tree in `ErrorBoundary` inside `App.tsx`. + +**Why**: Isolates crashes to the component that failed, not the whole SPA. + +--- + +## ✅ Completed (Phase 2 — Consolidation) + +### Backend + +#### A. Database Migration System + +**Priority**: High (blocks schema evolution) + +**Current**: Schema is created inline in `database.ts` on startup. No version tracking. + +**Needed**: + +``` +backend/src/db/migrations/ + 001_initial.sql + 002_add_exam_tags.sql + 003_add_user_preferences.sql +``` + +With a `schema_migrations` table tracking applied versions. Run on startup, ordered by filename. + +**Why**: Required before any schema change. Without it, adding columns = production downtime or manual ALTER TABLE. + +#### B. Database Connection Pooling / Migration to PostgreSQL + +**Priority**: Medium + +**Current**: SQLite with `better-sqlite3`. Single connection, file-based. + +**Why SQLite is fine for now**: Single-node deployment, no concurrent writes expected. + +**When to migrate**: + +- Multi-instance deployments +- Concurrent writes (multiple admins) +- Need for backups, replication, or managed hosting + +**Path**: Abstract `getDb()` behind an interface. Swap implementation. + +#### C. Email Delivery Reliability + +**Priority**: Medium + +**Current**: Nodemailer with SMTP. No queue, no retry. + +**Needed**: + +- Abstract email behind an interface (`IEmailService`) +- Implementations: `SmtpEmailService`, `ConsoleEmailService` (dev), `SendGridEmailService` +- Add retry with exponential backoff +- Consider a job queue (Bull + Redis) for high volume + +#### D. Comprehensive API Testing + +**Priority**: High + +**Current**: Vitest installed but no tests. + +**Needed**: + +``` +backend/src/tests/ + auth.test.ts — register, login, me, change password + exams.test.ts — CRUD + results.test.ts — submit, list, delete + admin.test.ts — user management, stats +``` + +Use `supertest` for HTTP-level tests, in-memory SQLite for isolation. + +#### E. Environment Configuration Management ✅ + +**Created**: `backend/src/config.ts` + +Centralized environment variable management with: + +- `env()` helper for optional vars with defaults +- `env.required()` helper for mandatory vars (throws with clear error) +- Type-safe exports: `JWT_SECRET`, `PORT`, `DB_PATH`, `SMTP_HOST`, `SMTP_PORT`, `EMAIL_FROM`, `FRONTEND_URL`, `NODE_ENV` +- `tokens.ts` updated to use `config.JWT_SECRET` instead of `process.env` + +This provides fail-fast validation at startup and a single source of truth for all environment configuration. + +### Frontend + +#### F. Remaining Component API Migration ✅ + +**Priority**: High + +All components migrated to API modules. Zero raw `apiFetch()` calls remain in `.tsx` files: + +| Component | API Module Used | +| -------------------- | --------------- | +| `Settings.tsx` | `authApi` | +| `AdminDashboard.tsx` | `adminApi` | +| `SetupWizard.tsx` | `setupApi` | +| `ExamRunner.tsx` | `resultApi` | +| `Workspace.tsx` | `authApi` | + +#### G. Extract Exam/Result State from App.tsx + +**Priority**: High — NOT completed in Phase 2 + +**Current**: `App.tsx` holds `exam` and `history` in local state, passed via props and `navigate(state)`. + +**Needed**: Dedicated contexts: + +``` +frontend/src/contexts/ + ExamContext.tsx — current exam, load, unload + HistoryContext.tsx — result history, review data +``` + +This decouples state from routing and enables features like: + +- Resume interrupted exam +- Background auto-save +- Offline mode (PWA) + +#### H. React Error Boundary Integration ✅ + +**Priority**: Medium + +**Created**: `frontend/src/components/ErrorBoundary.tsx` + +**Integrated**: Wrapped the entire `` tree in `ErrorBoundary` inside `App.tsx`. + +Consider also wrapping specific high-risk sections (exam editor, admin dashboard) individually for finer-grained isolation. + +#### I. Frontend Testing + +**Priority**: Medium — NOT completed + +**Needed**: + +``` +frontend/src/tests/ + api/ — mock API tests + components/ — React Testing Library + utils/ — unit tests for validation, slug, etc. +``` + +Start with API module tests (mock fetch) and utility function tests. + +### DevOps / Infrastructure + +#### J. Health Check Endpoint Enhancement + +**Priority**: Medium — NOT completed + +**Current**: `/api/health` returns `{ status: 'ok' }` + +**Needed**: + +```json +{ + "status": "healthy", + "timestamp": 1234567890, + "version": "1.2.3", + "checks": { + "database": "connected", + "email": "configured", + "disk": "ok" + } +} +``` + +#### K. Docker Production Optimization + +**Priority**: Medium — NOT completed + +**Current**: Single Dockerfile, no multi-stage build. + +**Needed**: Multi-stage build: + +1. `builder` — install deps, build frontend, compile backend +2. `production` — copy only `dist/`, `node_modules` (prod), runtime files + +This reduces image size from ~500MB to ~150MB. + +#### L. Backup Strategy + +**Priority**: High for production — NOT completed + +**Current**: SQLite file on disk.
