# ASLE Deployment Guide

## Prerequisites

- Docker and Docker Compose
- Node.js 20+ (for local development)
- Foundry (for contract deployment)
- PostgreSQL 15+ (or use Docker)
- Environment variables configured

## Environment Setup

1. Copy environment files:
```bash
cp backend/.env.example backend/.env
cp frontend/.env.example frontend/.env.local
```

2. Configure environment variables in `.env` files

## Database Setup

1. Start PostgreSQL:
```bash
docker-compose up -d postgres
```

2. Run migrations:
```bash
cd backend
npm install
npx prisma migrate deploy
npx prisma generate
```

## Contract Deployment

### Local Development

```bash
cd contracts
forge build
forge test

# Deploy to local network
forge script script/Deploy.s.sol:DeployScript --rpc-url http://localhost:8545 --broadcast --private-key $PRIVATE_KEY
```

### Mainnet/Testnet Deployment

1. Set environment variables:
```bash
export PRIVATE_KEY=your_private_key
export RPC_URL=https://your-rpc-url
export DEPLOYER_ADDRESS=your_deployer_address
```

2. Deploy:
```bash
forge script script/Deploy.s.sol:DeployScript \
  --rpc-url $RPC_URL \
  --broadcast \
  --verify \
  --etherscan-api-key $ETHERSCAN_API_KEY \
  --private-key $PRIVATE_KEY
```

3. Update environment files with deployed addresses

## Backend Deployment

### Local Development

```bash
cd backend
npm install
npm run dev
```

### Docker

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

### Production

1. Build image:
```bash
cd backend
docker build -t asle-backend .
```

2. Run container:
```bash
docker run -d \
  --name asle-backend \
  -p 4000:4000 \
  --env-file backend/.env \
  asle-backend
```

## Frontend Deployment

### Local Development

```bash
cd frontend
npm install
npm run dev
```

### Docker

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

### Production (Vercel/Next.js)

```bash
cd frontend
npm install
npm run build
npm start
```

Or use Vercel:
```bash
vercel deploy --prod
```

## Full Stack Deployment

### Development

```bash
docker-compose up
```

### Production

1. Set production environment variables
2. Update `docker-compose.prod.yml` if needed
3. Deploy:
```bash
docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
```

## Health Checks

- Backend: `http://localhost:4000/health`
- Frontend: `http://localhost:3000`
- GraphQL: `http://localhost:4000/graphql`

## Monitoring

- Check logs: `docker-compose logs -f`
- Database access: `docker-compose exec postgres psql -U asle -d asle`
- Redis access: `docker-compose exec redis redis-cli`

## Troubleshooting

1. **Database connection errors**: Check PostgreSQL is running and credentials are correct
2. **Contract deployment fails**: Verify RPC URL and private key
3. **Frontend can't connect**: Check `NEXT_PUBLIC_API_URL` is set correctly
4. **Port conflicts**: Update ports in `docker-compose.yml`

## Security Checklist

- [ ] Change all default passwords
- [ ] Use strong JWT_SECRET
- [ ] Configure CORS properly
- [ ] Enable HTTPS in production
- [ ] Set up firewall rules
- [ ] Regular security updates
- [ ] Backup database regularly
- [ ] Monitor logs for suspicious activity

## Backup and Recovery

### Database Backup

```bash
docker-compose exec postgres pg_dump -U asle asle > backup_$(date +%Y%m%d).sql
```

### Database Restore

```bash
docker-compose exec -T postgres psql -U asle asle < backup_20240101.sql
```
