Quick Start

Install dependencies

npm install

This installs all workspace dependencies (backend, frontend, mobile, scraper) via npm workspaces.

Development

# Start everything (backend + frontend)
npm run dev

# Start only backend
npm run dev:backend

# Start only frontend
npm run dev:frontend

# Start mobile app
npx turbo run dev --filter=frontend-mobile

Build

# Build all apps
npm run build

# Build only frontend
npm run build:web

Test

# Run all tests
npm test

# Test specific app
npm test --workspace=farma-clic-backend
npm test --workspace=farma-clic-frontend

Docker Setup

Runs the full stack (backend, frontend, Redis, Postgres) with a single command.

# Copy and configure environment (optional - defaults work for local dev)
cp apps/backend/.env.example apps/backend/.env

docker compose up --build

App available at http://localhost:4000 (frontend) and http://localhost:3001 (backend API).

First run - create an admin user:

docker compose exec backend node create-admin.js
# Default: admin / admin123 - change after first login

Seed sample pharmacies:

docker compose exec backend node seed.js

Stop:

docker compose down

Database is persisted in named Docker volumes (backend_data, postgres_data). To wipe:

docker compose down -v

Manual Setup

1. Install Redis

Ubuntu/Debian:

sudo apt-get install redis-server
sudo systemctl start redis-server

macOS:

brew install redis
brew services start redis

Docker:

docker run -d -p 6379:6379 redis:alpine

Verify: redis-cli ping should respond PONG.

2. Configure Environment (Optional)

Create apps/backend/.env:

REDIS_HOST=localhost
REDIS_PORT=6379
REDIS_PASSWORD=
SESSION_SECRET=your-secret-key-here

3. Initialize Database

# Seed sample pharmacies
npm run dev --workspace=farma-clic-backend -- run seed

# Create admin user (default: admin / admin123)
npm run dev --workspace=farma-clic-backend -- run create-admin

4. Run

npm run dev

API Endpoints

Public

GET /api/medicines/search?q=<query> - Search medicines (CIMA API, cached in Redis)
GET /api/medicines/:nregistro - Medicine details
GET /api/medicines/:nregistro/pharmacies - Pharmacies selling a medicine
GET /api/pharmacies - All pharmacies

Auth

POST /api/auth/login - Login
POST /api/auth/logout - Logout
GET /api/auth/check - Check auth status

Admin (requires authentication)

POST /api/admin/pharmacies - Add pharmacy
PUT /api/admin/pharmacies/:id - Update pharmacy
DELETE /api/admin/pharmacies/:id - Delete pharmacy
GET /api/admin/medicines?q=<query> - Search medicines
GET /api/admin/pharmacies/:id/medicines - Linked medicines
POST /api/admin/pharmacy-medicines - Link medicine to pharmacy
PUT /api/admin/pharmacy-medicines/:id - Update price/stock
DELETE /api/admin/pharmacy-medicines/:id - Remove link

Database Schema

SQLite Tables

pharmacies: id, name, address, phone, latitude, longitude

pharmacy_medicines: id, pharmacy_id, medicine_nregistro, medicine_name, price, stock

users: id, username, password_hash, created_at

Redis Cache

medicines:search:{query} - Search results (TTL: 1h)
medicine:{nregistro} - Medicine details (TTL: 24h)

Mobile App Setup

Prerequisites

Node.js v20+
Expo CLI: npm install -g expo-cli
EAS CLI: npm install -g eas-cli
iOS: Xcode + CocoaPods (Mac only)
Android: Android Studio + SDK

Development

# Install dependencies (already done via npm install at root)

# Start mobile dev server
npx turbo run dev --filter=frontend-mobile

# Scan QR code with Expo Go app

EAS Build

cd apps/frontend-mobile

# Development build
eas build --profile development --platform ios
eas build --profile development --platform android

# Production build
eas build --profile production --platform android
eas build --profile production --platform ios

Environment Configuration

// apps/frontend-mobile/constants/config.ts
const ENV = {
  development: { API_BASE_URL: 'http://localhost:3001/api' },
  production: { API_BASE_URL: 'https://your-production-api.com/api' },
};

Troubleshooting

Redis Connection Issues

redis-cli ping          # Should respond: PONG
redis-server            # Start if not running
redis-cli FLUSHALL      # Clear cache

CIMA API Timeout

Check internet connection
CIMA API may be temporarily unavailable
App falls back to cached data

Database Reset

cd apps/backend
rm database.sqlite
npm run seed
npm run create-admin

Turborepo Cache Issues

npx turbo clean         # Clear Turbo cache
rm -rf node_modules     # Full reset
npm install
