# Local Development Setup

## PostgreSQL Only (Recommended for Local Development)

Voor lokale development heb je alleen PostgreSQL nodig. De backend en frontend draaien lokaal op je MacBook.

### Start PostgreSQL

```bash
# Start alleen PostgreSQL
docker-compose -f docker-compose.dev.yml up -d

# Check status
docker-compose -f docker-compose.dev.yml ps

# Check logs
docker-compose -f docker-compose.dev.yml logs -f postgres
```

### Connection String

```env
DATABASE_TYPE=postgres
DATABASE_URL=postgresql://cmdb:cmdb-dev@localhost:5432/cmdb_insight
```

Of individuele variabelen:

```env
DATABASE_TYPE=postgres
DATABASE_HOST=localhost
DATABASE_PORT=5432
DATABASE_NAME=cmdb_insight
DATABASE_USER=cmdb
DATABASE_PASSWORD=cmdb-dev
```

### Stop PostgreSQL

```bash
docker-compose -f docker-compose.dev.yml down
```

### Reset Database

```bash
# Stop en verwijder volume
docker-compose -f docker-compose.dev.yml down -v

# Start opnieuw
docker-compose -f docker-compose.dev.yml up -d
```

### Connect to Database

```bash
# Via psql
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -d cmdb_insight

# Of direct
psql postgresql://cmdb:cmdb-dev@localhost:5432/cmdb_insight
```

### Useful Commands

```bash
# List databases
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -c "\l"

# List tables
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -d cmdb_insight -c "\dt"

# Check database size
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -d cmdb_insight -c "
  SELECT pg_size_pretty(pg_database_size('cmdb_insight')) as size;
"

# Count objects
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -d cmdb_insight -c "
  SELECT object_type_name, COUNT(*) 
  FROM objects 
  GROUP BY object_type_name;
"
```

## Full Stack (Alternative)

Als je de hele stack in Docker wilt draaien:

```bash
docker-compose up -d
```

Dit start:
- PostgreSQL
- Backend (in Docker)
- Frontend (in Docker)

## Backend Development

Met alleen PostgreSQL draaiend:

```bash
# In backend directory
cd backend
npm install
npm run dev
```

Backend draait op `http://localhost:3001`

## Frontend Development

```bash
# In frontend directory
cd frontend
npm install
npm run dev
```

Frontend draait op `http://localhost:5173`

## Environment Variables

Maak een `.env` bestand in de root:

```env
# Database (voor backend)
DATABASE_TYPE=postgres
DATABASE_URL=postgresql://cmdb:cmdb-dev@localhost:5432/cmdb_insight

# Jira (optioneel)
JIRA_HOST=https://jira.zuyderland.nl
JIRA_PAT=your_token

# AI (optioneel)
ANTHROPIC_API_KEY=your_key
```

## Database Access

### Quick Access

**Using the script:**
```bash
# Connect using psql
./scripts/open-database.sh psql

# Or via Docker
./scripts/open-database.sh docker

# Or get connection string for GUI tools
./scripts/open-database.sh url
```

**Direct psql command:**
```bash
psql postgresql://cmdb:cmdb-dev@localhost:5432/cmdb_insight
```

**Via Docker:**
```bash
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -d cmdb_insight
```

### GUI Tools

**pgAdmin** (Free, Web-based):
- Download: https://www.pgadmin.org/download/
- Connection: `postgresql://cmdb:cmdb-dev@localhost:5432/cmdb_insight`

**DBeaver** (Free, Cross-platform):
- Download: https://dbeaver.io/download/
- Create new PostgreSQL connection with connection string above

**TablePlus** (macOS, Paid but has free tier):
- Download: https://tableplus.com/
- Create new PostgreSQL connection

### Useful SQL Commands

```sql
-- List all tables
\dt

-- Describe a table structure
\d objects
\d attribute_values
\d classification_history

-- View object counts
SELECT object_type_name, COUNT(*) 
FROM objects 
GROUP BY object_type_name;

-- View classification history
SELECT * FROM classification_history 
ORDER BY timestamp DESC 
LIMIT 10;

-- Check database size
SELECT pg_size_pretty(pg_database_size('cmdb_insight')) as size;
```

---

## Troubleshooting

### Port Already in Use

Als poort 5432 al in gebruik is:

```yaml
# In docker-compose.dev.yml, wijzig:
ports:
  - "5433:5432"  # Gebruik 5433 lokaal
```

En update je `.env`:
```env
DATABASE_PORT=5433
```

### Connection Refused

```bash
# Check of container draait
docker ps | grep postgres

# Check logs
docker-compose -f docker-compose.dev.yml logs postgres

# Test connection
docker-compose -f docker-compose.dev.yml exec postgres pg_isready -U cmdb
```

### Database Not Found

De database wordt automatisch aangemaakt bij eerste start van de backend. Of maak handmatig:

```bash
docker-compose -f docker-compose.dev.yml exec postgres psql -U cmdb -c "CREATE DATABASE cmdb_insight;"
```
