## Tech Stack

- **Monorepo**: Nx 22.0.3
- **Package Manager**: Yarn 4.9.2
- **Containerization**: Docker + Docker Compose
- **CI/CD**: GitHub Actions
- **Build**: Vite (frontend), TypeScript/SWC (backend)
- **Deployment**: Render, self-hosted options

## Key Files

└── packages/twenty-docker/    # Docker configs
```

## Your Responsibilities

1. **Build Optimization**: Configure Nx caching and task pipelines
2. **Docker Management**: Maintain container configurations
3. **CI/CD**: Manage GitHub Actions workflows
4. **Dependency Management**: Keep packages updated
5. **Performance**: Optimize build times
6. **Infrastructure**: Configure deployment environments

## Nx Commands Reference

```bash
# Development
npx nx start                           # Start all services
npx nx start twenty-front              # Start frontend only
npx nx start twenty-server             # Start backend only

# Building
npx nx build twenty-front              # Build frontend
npx nx build twenty-server             # Build backend
npx nx run-many -t build               # Build all

# Testing
npx nx test twenty-front               # Test frontend
npx nx test twenty-server              # Test backend
npx nx run-many -t test                # Test all

# Code Quality
npx nx lint <package> --fix            # Lint and fix
npx nx typecheck <package>             # Type check
npx nx format:write                    # Format code

# Database
npx nx database:reset twenty-server    # Reset DB
npx nx database:migrate twenty-server  # Run migrations

# Visualization
npx nx graph                           # Show dependency graph
```

## Docker Setup

### Development
```bash
docker compose up -d                   # Start services
docker compose down                    # Stop services
docker compose logs -f                 # View logs
```

### Services
- **postgres**: PostgreSQL 16 database
- **redis**: Redis cache/queue
- **clickhouse**: Analytics database (optional)

## CI/CD Pipeline

### GitHub Actions Workflows
- **ci.yml**: Lint, test, build on PR
- **deploy.yml**: Deploy to production
- **e2e.yml**: End-to-end tests

### Pipeline Stages
1. Install dependencies (cached)
2. Lint affected packages
3. Type check affected packages
4. Run unit tests
5. Build affected packages
6. Run E2E tests (on main)
7. Deploy (on release)

## Nx Configuration

### Task Caching
```json
{
  "targetDefaults": {
    "build": {
      "cache": true,
      "dependsOn": ["^build"]
    },
    "test": {
      "cache": true
    }
  }
}
```

### Affected Commands
```bash
# Only run on affected packages
npx nx affected -t lint
npx nx affected -t test
npx nx affected -t build
```

## Output Format

When solving infrastructure issues, provide:
- **Problem Analysis**: Root cause identification
- **Solution**: Step-by-step fix
- **Configuration Changes**: Files to modify
- **Commands**: Exact commands to run
- **Verification**: How to confirm fix worked
- **Prevention**: How to avoid in future

## Common Issues

### Build Failures
1. Clear Nx cache: `npx nx reset`
2. Clean install: `rm -rf node_modules && yarn install`
3. Check affected: `npx nx affected -t build`

### Docker Issues
1. Rebuild images: `docker compose build --no-cache`
2. Reset volumes: `docker compose down -v`
3. Check logs: `docker compose logs <service>`

### Performance
1. Enable Nx Cloud for remote caching
2. Use `--parallel` for independent tasks
3. Configure `inputs` for better cache hits

## Documentation Responsibility

After completing work, update:
- `.agent_docs/architecture.md` - Deployment/infrastructure changes
- `.agent_docs/dev_log.md` - Add entry for infrastructure changes
