# Pantry - Local Development Setup

Self-hosted household pantry management app with barcode scanning.

## 🚀 Quick Start

### Prerequisites

- **Docker** & **Docker Compose** (for Supabase backend)
- **Bun** (for Nuxt frontend) - Install: `curl -fsSL https://bun.sh/install | bash`
- **Git**

### 1. Clone & Setup

```bash
git clone https://gitea.jeanlucmakiola.de/pantry-app/pantry.git
cd pantry
```

### 2. Start Supabase (Backend)

```bash
# Start all Supabase services
docker-compose up -d

# Wait ~10 seconds for services to initialize
# Check status
docker-compose ps
```

**Services running:**
- PostgreSQL: `localhost:5432`
- Supabase API: `http://localhost:54321`
- Supabase Studio: `http://localhost:54323` (admin UI)

### 3. Apply Database Migrations

The migrations are automatically applied on first startup via `/docker-entrypoint-initdb.d`.

To verify:
```bash
docker-compose exec db psql -U postgres -d postgres -c "\dt"
```

You should see: `inventory_items`, `products`, `tags`, `units`, `item_tags`

### 4. Start Nuxt App (Frontend)

```bash
cd app
bun install
bun run dev
```

**App running:** `http://localhost:3000`

### 5. Open & Test

1. Visit `http://localhost:3000`
2. Click "Add Manually" to create your first inventory item
3. Access Supabase Studio at `http://localhost:54323` to view database

## 🔧 Common Tasks

### View Logs

```bash
# All services
docker-compose logs -f

# Specific service
docker-compose logs -f db
docker-compose logs -f auth
```

### Reset Database

```bash
# Stop services
docker-compose down -v

# Restart (migrations auto-apply)
docker-compose up -d
```

### Access Database

```bash
# psql
docker-compose exec db psql -U postgres -d postgres

# Supabase Studio (GUI)
# http://localhost:54323
```

### Run Migrations Manually

```bash
# If you add new migrations after initial setup
docker-compose exec db psql -U postgres -d postgres -f /docker-entrypoint-initdb.d/003_helper_functions.sql
```

### Create Test User

```bash
# Via Supabase Studio: http://localhost:54323
# → Authentication → Add User
# Email: test@example.com
# Password: password123

# Or via curl:
curl http://localhost:54321/auth/v1/signup \
  -H "apikey: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." \
  -H "Content-Type: application/json" \
  -d '{"email":"test@example.com","password":"password123"}'
```

## 🧪 Testing Features

### 1. Inventory Management
- Add items manually via form
- Edit quantities with +/- buttons
- Delete items
- View expiry warnings

### 2. Tags & Organization
- Pre-seeded tags: Fridge, Freezer, Pantry, Dairy, Vegan, etc.
- Multi-select tags when adding items
- Color-coded badges

### 3. Units
- 30 pre-seeded units (g, kg, L, cups, pieces, etc.)
- Automatic conversion support

### 4. Barcode Scanning (Week 3 - In Progress)
- Camera access (requires HTTPS in production)
- Manual barcode entry fallback

## 🐛 Troubleshooting

### Port Conflicts

If ports 5432, 54321, or 3000 are in use:

```bash
# Check what's using the port
sudo lsof -i :5432

# Option 1: Stop conflicting service
# Option 2: Change port in docker-compose.yml
```

### Database Connection Refused

```bash
# Wait for PostgreSQL to fully start
docker-compose logs db | grep "ready to accept connections"

# If stuck, restart
docker-compose restart db
```

### Migrations Not Applied

```bash
# Verify migrations directory is mounted
docker-compose exec db ls -la /docker-entrypoint-initdb.d

# Manually apply
docker-compose exec db bash
cd /docker-entrypoint-initdb.d
for f in *.sql; do psql -U postgres -d postgres -f "$f"; done
```

### Frontend: Module Not Found

```bash
cd app
rm -rf node_modules bun.lock .nuxt
bun install
bun run dev
```

- Auto-confirm emails (no SMTP needed)
- Anyone can sign up
- JWT tokens valid for 1 hour

**Create Admin User:**

```sql
-- Via psql
docker-compose exec db psql -U postgres -d postgres

INSERT INTO auth.users (id, email, encrypted_password, email_confirmed_at)
VALUES (
  gen_random_uuid(),
  'admin@pantry.local',
  crypt('admin123', gen_salt('bf')),
  NOW()
);
```

---

## 🌐 Environment Variables

**.env** (root)
```bash
POSTGRES_PASSWORD=postgres
JWT_SECRET=your-secret-here
ANON_KEY=<supabase-anon-key>
SERVICE_ROLE_KEY=<supabase-service-role-key>
```

**app/.env** (Nuxt)
```bash
NUXT_PUBLIC_SUPABASE_URL=http://localhost:54321
NUXT_PUBLIC_SUPABASE_ANON_KEY=<same-as-above>
```

## 📈 Development Workflow

1. **Make changes** to Nuxt app → Hot reload at `localhost:3000`
2. **Database changes** → Create new migration in `supabase/migrations/`
3. **Test** → Add items, scan barcodes, check database
4. **Commit** → Feature branch → PR to `develop`
