Zylem - Gamified Learning (Offline-first)

This repo contains a full scaffold: backend (Node/Express/Postgres), frontend (Vite+React PWA), docker-compose and CI.

Stepwise setup (local, development)

1. Clone repo to your machine.
2. Install Docker and Docker Compose.
3. From repo root run:

   docker compose up --build
   

   This starts Postgres, backend (port 4000) and frontend (port 3000).
4. Apply DB migrations and seed:

   docker compose exec db psql -U postgres -d zylem -f /app/backend/src/db/migrations.sql
   docker compose exec db psql -U postgres -d zylem -f /app/backend/seed/seed.sql
   

   (If paths differ, run psql from your host using DATABASE_URL)
5. Visit:
   • Frontend: http://localhost:3000
   • Backend API: http://localhost:4000

Production notes

• Configure DATABASE_URL and JWT_SECRET in environment variables.
• Use a managed Postgres for production, and serve the frontend via CDN or static hosting.
• Replace the simple auth with hashed passwords and proper validation.
