## Local Development

### Prerequisites

- Node.js 20+
- Docker & Docker Compose
- kubectl configured for the k8s cluster
- SSH tunnel to production database (port 54320)

### 1. Start Local Services

```bash
cd /home/kelly/git/dispensary-scraper

# Start local postgres and minio
docker start dutchie-postgres dutchie-minio

# Or use docker-compose for fresh setup
docker compose up -d
```

### 2. Environment Variables

```bash
# Production database (via SSH tunnel)
export DATABASE_URL="postgresql://dutchie:dutchie_local_pass@localhost:54320/dutchie_menus"
```

### 3. Run Backend

```bash
cd backend
npm install
npm run dev
# API available at http://localhost:3010
```

### 4. Run Frontend

```bash
cd frontend
npm install
npm run dev
# UI available at http://localhost:5173
```

### 5. Run Migrations

```bash
cd backend
DATABASE_URL="postgresql://dutchie:dutchie_local_pass@localhost:54320/dutchie_menus" npx tsx src/db/migrate.ts
```

---

## Database Architecture

### Two Databases

| Database | Port | User | Purpose |
|----------|------|------|---------|
| `dutchie_menus` | 54320 | dutchie | **Production** - SSH tunnel to remote k8s postgres |
| `dispensary_scraper` | 5432 | scraper | **Remote only** - Accessed via k8s pods |

**Local development uses port 54320** (SSH tunnel to production).

### Key Tables

| Table | Purpose |
|-------|---------|
| `dispensaries` | Master list of dispensaries (from AZDHS) with crawl metadata |
| `stores` | Legacy table - being migrated to dispensaries |
| `products` | Scraped product data |
| `proxies` | Proxy pool for bot detection avoidance |
| `crawl_jobs` | Crawl job history and status |

### Dispensary Crawl Fields

The `dispensaries` table now contains crawl metadata:
- `provider_type` - Menu provider (dutchie, jane, etc.)
- `menu_provider` - Detected provider for crawling
- `crawler_mode` - 'production' or 'sandbox'
- `crawl_status` - Current status (idle, running, ok, error)
- `menu_url` - URL to crawl

---

## Kubernetes Deployment

### Namespace

```bash
kubectl get all -n dispensary-scraper
```

### Image Registry

Images are stored at `code.cannabrands.app/creationshop/`:
- `dispensary-scraper:latest` - Backend
- `dispensary-scraper-frontend:latest` - Frontend

### Deploy New Code

The CI/CD pipeline builds and deploys automatically on push to master. To manually deploy:

```bash
# Restart deployment to pull latest image
kubectl rollout restart deployment/scraper -n dispensary-scraper

# Check status
kubectl rollout status deployment/scraper -n dispensary-scraper

# View logs
kubectl logs -f deployment/scraper -n dispensary-scraper
```

### Run Migrations on Remote

```bash
# Copy migration file to pod
kubectl cp backend/migrations/029_link_dutchie_stores_to_dispensaries.sql \
  dispensary-scraper/scraper-POD-NAME:/tmp/migration.sql

# Execute via psql in pod
kubectl exec -n dispensary-scraper deployment/scraper -- \
  sh -c 'PGPASSWORD=$POSTGRES_PASSWORD psql -h $POSTGRES_HOST -U $POSTGRES_USER -d $POSTGRES_DB -f /tmp/migration.sql'
```

---

## Running Crawlers

### Remote (Production)

Crawlers should run on the k8s cluster, not locally.

```bash
# Run crawl script inside pod
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node dist/scripts/queue-dispensaries.js --production

# Or for a specific dispensary
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node -e "require('./dist/services/crawler-jobs').runDutchieMenuCrawlJob(112)"
```

### Trigger via API

```bash
# Queue all Dutchie dispensaries
curl -X POST https://dispos.crawlsy.com/api/crawl/queue-all?type=dutchie
```

### Local Testing

For code development/testing only:

```bash
cd backend
DATABASE_URL="postgresql://dutchie:dutchie_local_pass@localhost:54320/dutchie_menus" \
  npx tsx src/scripts/queue-dispensaries.ts --production --limit=1
```

---

## Proxy System

### How It Works

1. Proxies stored in `proxies` table with `active=true/false`
2. `getActiveProxy()` selects random active proxy
3. On bot detection, proxy gets 35-second in-memory cooldown
4. Permanent failures mark `active=false` in DB

### Adding New Proxies

```sql
INSERT INTO proxies (ip, port, protocol, active)
VALUES ('123.45.67.89', 3128, 'http', true);
```

---

## Common Tasks

### Check Crawl Status

```bash
# Via kubectl
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node -e "require('pg').Pool({connectionString: process.env.DATABASE_URL}).query('SELECT id, name, crawl_status FROM dispensaries WHERE provider_type = \\'dutchie\\' LIMIT 10').then(r => console.log(r.rows))"

# Via admin UI
# https://dispos.crawlsy.com/schedule
```

### View Recent Products

```bash
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node -e "require('pg').Pool({connectionString: process.env.DATABASE_URL}).query('SELECT COUNT(*), MAX(updated_at) FROM products').then(r => console.log(r.rows))"
```

### Restart Stuck Crawl

```sql
UPDATE dispensaries SET crawl_status = 'idle' WHERE crawl_status = 'running';
```

---

## Troubleshooting

### Pod Not Starting

```bash
kubectl describe pod -n dispensary-scraper -l app=scraper
kubectl logs -n dispensary-scraper -l app=scraper --previous
```

### Database Connection Issues

```bash
# Test from pod
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node -e "require('pg').Pool({connectionString: process.env.DATABASE_URL}).query('SELECT 1').then(() => console.log('OK'))"
```

### Proxy Issues

```bash
# Check active proxy count
kubectl exec -n dispensary-scraper deployment/scraper -- \
  node -e "require('pg').Pool({connectionString: process.env.DATABASE_URL}).query('SELECT COUNT(*) FROM proxies WHERE active = true').then(r => console.log('Active proxies:', r.rows[0].count))"
```
