# Deployment & CI/CD

Ship code reliably and automatically.

## Deployment Philosophy

### The Deployment Pipeline

```
Code → Build → Test → Stage → Production

 │       │       │       │        │
 └───────┴───────┴───────┴────────┘
         Automated, Repeatable
```

### Principles

1. **Automate everything** - No manual steps
2. **Fail fast** - Catch issues early
3. **Rollback ready** - Always have an escape
4. **Environment parity** - Dev ≈ Staging ≈ Prod
5. **Observability** - Know what's happening

## GitHub Actions

### Basic Workflow

```yaml
# .github/workflows/ci.yml
name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      
      - name: Install dependencies
        run: npm ci
      
      - name: Run linter
        run: npm run lint
      
      - name: Run tests
        run: npm test
      
      - name: Build
        run: npm run build
```

### Matrix Builds

```yaml
jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [18, 20, 22]
        os: [ubuntu-latest, macos-latest]
    
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}
      - run: npm ci
      - run: npm test
```

### Deploy on Push to Main

```yaml
name: Deploy

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      
      - run: npm ci
      - run: npm run build
      
      - name: Deploy to Vercel
        uses: amondnet/vercel-action@v25
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.VERCEL_ORG_ID }}
          vercel-project-id: ${{ secrets.VERCEL_PROJECT_ID }}
          vercel-args: '--prod'
```
