# Appwrite Backend-as-a-Service Template

## Overview
Appwrite is an open-source backend-as-a-service platform that abstracts and simplifies complex development tasks behind a simple REST API.

## Quick Start
```bash
# Create docker-compose.yml with the content below
docker-compose up -d
```

## Docker Compose

## Client SDKs

### JavaScript/TypeScript
```javascript
import { Client, Account, Databases } from 'appwrite'

const client = new Client()
  .setEndpoint('http://localhost/v1')
  .setProject('YOUR_PROJECT_ID')

const account = new Account(client)
const databases = new Databases(client)

// Authentication
await account.createEmailSession('user@example.com', 'password')

// Database operations
const response = await databases.createDocument(
  'YOUR_DATABASE_ID',
  'YOUR_COLLECTION_ID',
  ID.unique(),
  { title: 'Hello World', content: 'This is my first post' }
)
```

### Python
```python
from appwrite.client import Client
from appwrite.services.account import Account
from appwrite.services.databases import Databases

client = Client()
client.set_endpoint('http://localhost/v1')
client.set_project('YOUR_PROJECT_ID')

account = Account(client)
databases = Databases(client)

# Authentication
account.create_email_session('user@example.com', 'password')

# Database operations
databases.create_document(
    'YOUR_DATABASE_ID',
    'YOUR_COLLECTION_ID',
    ID.unique(),
    { 'title': 'Hello World', 'content': 'This is my first post' }
)
```

### PHP
```php
use Appwrite\Client;
use Appwrite\Services\Account;
use Appwrite\Services\Databases;

$client = new Client();
$client->setEndpoint('http://localhost/v1')
       ->setProject('YOUR_PROJECT_ID');

$account = new Account($client);
$databases = new Databases($client);

// Authentication
$account->createEmailSession('user@example.com', 'password');

// Database operations
$databases->createDocument(
    'YOUR_DATABASE_ID',
    'YOUR_COLLECTION_ID',
    ID::unique(),
    ['title' => 'Hello World', 'content' => 'This is my first post']
);
```

## Reverse Proxy (Traefik)
```yaml
labels:
  - "traefik.enable=true"
  - "traefik.http.routers.appwrite.rule=Host(`api.yourdomain.com`)"
  - "traefik.http.routers.appwrite.tls=true"
  - "traefik.http.routers.appwrite.tls.certresolver=letsencrypt"
  - "traefik.http.services.appwrite.loadbalancer.server.port=80"
```

## Backup Strategy
```bash
# Backup Appwrite data
docker run --rm -v appwrite-uploads:/storage/uploads -v $(pwd):/backup alpine tar czf /backup/appwrite-uploads.tar.gz -C /storage/uploads .
docker run --rm -v appwrite-cache:/storage/cache -v $(pwd):/backup alpine tar czf /backup/appwrite-cache.tar.gz -C /storage/cache .
docker run --rm -v appwrite-config:/storage/config -v $(pwd):/backup alpine tar czf /backup/appwrite-config.tar.gz -C /storage/config .

# Backup database
docker exec appwrite-mariadb mysqldump -u root -pinstance-password appwrite > appwrite-db-backup.sql

# Restore database
docker exec -i appwrite-mariadb mysql -u root -pinstance-password appwrite < appwrite-db-backup.sql

# Restore Appwrite data
docker run --rm -v appwrite-uploads:/storage/uploads -v $(pwd):/backup alpine tar xzf /backup/appwrite-uploads.tar.gz -C /storage/uploads
docker run --rm -v appwrite-cache:/storage/cache -v $(pwd):/backup alpine tar xzf /backup/appwrite-cache.tar.gz -C /storage/cache
docker run --rm -v appwrite-config:/storage/config -v $(pwd):/backup alpine tar xzf /backup/appwrite-config.tar.gz -C /storage/config

# Restart after restore
docker-compose restart appwrite
```

## Performance Optimization
```yaml
# For better performance
environment:
  - _APP_REDIS_HOST=redis
  - _APP_REDIS_PORT=6379
  - _APP_CACHE_ENABLED=true
  - _APP_CACHE_QUOTA=100

# Resource limits
deploy:
  resources:
    limits:
      memory: 2G
      cpus: '2.0'
    reservations:
      memory: 1G
      cpus: '1.0'
```

## Security
- Change default passwords
- Use HTTPS in production
- Network access control
- Regular backups
- Monitor access logs

## Monitoring

### Health Checks
```bash
# Check Appwrite health
curl http://localhost/health

# Check service status
docker-compose ps
```

### Logs
```bash
# View logs
docker-compose logs -f appwrite

# Check specific service logs
docker-compose logs -f mariadb
docker-compose logs -f redis
```

## Troubleshooting
- **Database connection**: Check MariaDB configuration
- **Redis connection**: Verify Redis settings
- **Function execution**: Check executor logs
- **Email issues**: Verify SMTP configuration
- **File uploads**: Check storage permissions

## Maintenance
```bash
# Restart services
docker-compose restart

# Update images
docker-compose pull && docker-compose up -d

# Clean up old data
docker exec appwrite-mariadb mysql -u root -pinstance-password -e "DELETE FROM appwrite.cache WHERE expires < UNIX_TIMESTAMP();"
```

## Advanced Features

### Real-time Subscriptions
```javascript
// Subscribe to document changes
client.subscribe('documents', response => {
  console.log('Document changed:', response.payload)
})
```

### Webhooks
```bash
# Create webhook
curl -X POST http://localhost/v1/webhooks \
  -H "Content-Type: application/json" \
  -H "X-Appwrite-Project: YOUR_PROJECT_ID" \
  -H "X-Appwrite-Key: YOUR_API_KEY" \
  -d '{"name":"My Webhook","events":["database.documents.create"],"url":"https://your-domain.com/webhook"}'
```

### Scheduled Tasks
```bash
# Create scheduled task
curl -X POST http://localhost/v1/functions/FUNCTION_ID/schedules \
  -H "Content-Type: application/json" \
  -H "X-Appwrite-Project: YOUR_PROJECT_ID" \
  -H "X-Appwrite-Key: YOUR_API_KEY" \
  -d '{"schedule":"0 9 * * 1","timezone":"America/New_York"}'
```

// Server-side authentication
async function authenticateUser(email, password) {
  try {
    const session = await account.createEmailSession(email, password)
    return session
  } catch (error) {
    throw new Error('Authentication failed')
  }
}
```
