Quick Start

1. Backend

cd server
npm install
npm run migrate:pg-to-mongo   # optional: copies existing PostgreSQL data into MongoDB
# OR if starting fresh (no PostgreSQL data to migrate):
# npm run seed
npm run dev

2. Frontend

cd client
npm install
npm run dev

3. Verify

• Frontend: http://localhost:5173
• Backend: http://localhost:5001
• Test API: http://localhost:5001/api/food/test

Environment Variables

Configure server/.env:

MONGODB_URI="mongodb://127.0.0.1:27017/pureintake"
POSTGRES_URL="postgresql://postgres:password@localhost:5432/pureintake" # optional, only for one-time migration
JWT_SECRET="your_secret_key"
PORT=5001
NODE_ENV="development"
ADMIN_EMAILS="*" # comma-separated admin emails; use * for local development

Admin Bulk Upload

• UI: /admin/bulk-upload (after login)
• API: POST /api/food/bulk
• Input: JSON array or CSV parsed by the admin panel

Quality & Safety Tooling

Type safety (TypeScript checks on JS)

cd client && npm run typecheck
cd server && npm run typecheck

Unit tests

cd client && npm run test:unit
cd server && npm run test:unit

E2E tests

cd client
npx playwright install chromium   # first time only
npm run test:e2e

Runtime hardening

• Request logging + process-level error monitoring (server)
• API rate limiting (/api global + stricter auth limiter)
• Response caching for public food catalog endpoints:
  • GET /api/food/search
  • GET /api/food/categories
• Frontend global error capture + improved ErrorBoundary fallback
• Vite bundle optimization with manual chunk splitting
