# Database Branching untuk CI/CD: Tutorial PostgreSQL + Neon di Helipod

Bayangkan setiap **pull request** di GitHub otomatis punya **database branch** sendiri, tanpa setup manual, tanpa tunggu menit, tanpa takut ngotorin production.

**Itu bukan mimpi.** Dengan Neon database branching + Helipod, itu jadi kenyataan.

## Kenapa Database Branching untuk CI/CD?

### Masalah Tanpa Branching

```
Developer A push code → Testing di staging → Database conflict!
Developer B push code → Testing di staging → Data campur aduk!
```

**Akhirnya:**
- Manual setup database buat testing
- Sering lupa cleanup branch lama
- Staging database sering "kotor" karena dipakai bareng

### Solusi: Database Branching

```
Pull Request #1 → Branch DB pr-1 → Isolated testing
Pull Request #2 → Branch DB pr-2 → Isolated testing
Pull Request #3 → Branch DB pr-3 → Isolated testing
```

**Hasilnya:**
- Setiap PR punya database sendiri
- Cleanup otomatis saat PR di-merge/ditutup
- Production database tetap bersih

## Cara Kerja Database Branching

Neon menggunakan **copy-on-write** untuk branching:

```
main branch (production data)
│
├── pr-123 branch (copy data saat branching)
│   └── Developer A bisa modify tanpa ngaruh main
│
├── pr-124 branch (copy data saat branching)
│   └── Developer B bisa modify tanpa ngaruh main
│
└── staging branch (copy data dari main)
    └── QA testing tanpa ngaruh production
```

**Yang bikin Neon spesial:**
- Branch instan (milidetik, bukan menit)
- Storage efisien (cuma simpan perbedaan)
- Scale to zero (branch idle = ga bayar)

## Setup CI/CD dengan Database Branching

### Langkah 1: Setup Neon + Helipod

1. Connect Neon ke Helipod (lihat [tutorial integrasi](/blog/neon-integration))
2. Aktifkan **Branch per environment**
3. Catat naming pattern yang dipakai

### Langkah 2: Konfigurasi GitHub Actions

Buat file `.github/workflows/preview.yml`:

```yaml
name: Preview Environment

on:
  pull_request:
    types: [opened, synchronize, reopened]

jobs:
  deploy-preview:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Create Neon Branch
        run: |
          # Buat branch database untuk PR ini
          BRANCH_NAME="pr-${{ github.event.pull_request.number }}"
          
          curl -X POST "https://console.neon.tech/api/v2/projects/{project_id}/branches" \
            -H "Authorization: Bearer ${{ secrets.NEON_API_KEY }}" \
            -H "Content-Type: application/json" \
            -d "{\"branch\": {\"parent_id\": \"main\"}, \"name\": \"$BRANCH_NAME\"}"
        env:
          NEON_API_KEY: ${{ secrets.NEON_API_KEY }}

      - name: Deploy to Helipod
        run: |
          # Deploy dengan branch database baru
          helipod deploy \
            --branch ${{ github.event.pull_request.number }} \
            --env DATABASE_URL="postgresql://..."
```

### Langkah 3: Cleanup Otomatis

Buat file `.github/workflows/cleanup.yml`:

```yaml
name: Cleanup Preview

on:
  pull_request:
    types: [closed]

jobs:
  cleanup:
    runs-on: ubuntu-latest
    steps:
      - name: Delete Neon Branch
        run: |
          BRANCH_NAME="pr-${{ github.event.pull_request.number }}"
          
          curl -X DELETE "https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}" \
            -H "Authorization: Bearer ${{ secrets.NEON_API_KEY }}"
        env:
          NEON_API_KEY: ${{ secrets.NEON_API_KEY }}
```

## Real Use Cases

### Use Case 1: Feature Development

**Situasi**: Developer sedang buat fitur baru yang butuh schema changes

```bash
# 1. Buat branch dari main
git checkout -b feature/new-payment

# 2. Helipod otomatis buat database branch
# Database branch: feature-new-payment

# 3. Jalankan migration
npx prisma migrate dev

# 4. Push kode
git push origin feature/new-payment

# 5. PR dibuat → Database branch siap untuk testing
```

### Use Case 2: Pull Request Testing

**Situasi**: QA perlu test PR sebelum di-merge

```
PR #123: Add payment feature
├── Code branch: feature/payment
├── Database branch: pr-123
├── Preview URL: https://pr-123.helipod.app
└── Database: Isolated, safe for testing
```

### Use Case 3: Hotfix Production

**Situasi**: Bug production, perlu fix sekarang

```bash
# 1. Buat hotfix branch
git checkout -b hotfix/critical-bug

# 2. Database branch otomatis dibuat
# Tapi ini dari production data!

# 3. Fix bug
# 4. Test di database branch
# 5. Merge ke main → Auto-deploy ke production
```

## Best Practices

### 1. Naming Pattern yang Konsisten

```env
# Gunakan pattern yang jelas
pr-{number}        → Pull request branches
staging            → Staging environment
feature-{name}     → Feature branches
hotfix-{name}      → Hotfix branches
```

### 2. Limit Branch Count

```bash
# Neon free tier: max 10 branches
# Neon pro: max 100 branches

# Pastikan cleanup otomatis jalan
# Delete branch saat PR closed/merged
```

### 3. Connection Pooling untuk Branches

```env
# Setiap branch butuh connection pooling
DATABASE_URL="postgresql://...@ep-xxx-pooler.region.neon.tech/dbname?pgbouncer=true"
```

### 4. Monitoring

```bash
# Monitor branch usage
# Di Helipod dashboard: Settings → Integrations → Neon
# Lihat jumlah branches dan storage usage
```

## FAQ

### Berapa biaya Neon untuk CI/CD?

Neon free tier mendukung **10 branches** dengan **512MB storage**. Untuk kebutuhan CI/CD yang lebih besar, Neon Pro tersedia mulai **$19/bulan**.

### Apakah database branch otomatis cleanup?

Ya! Di Helipod, kamu bisa setup cleanup otomatis saat environment dihapus. Untuk GitHub Actions, tambahkan workflow cleanup seperti yang dijelaskan di atas.

### Bagaimana jika butuh production data di branch?

Kamu bisa clone production branch ke feature branch. Data akan di-copy secara instan tanpa downtime.

### Bisakah saya pindah dari Supabase/Other ke Neon?

Ya! Lihat tutorial [migrasi database ke serverless PostgreSQL](/blog/migrasi-database-ke-serverless-postgresql).

## Checklist Setup CI/CD
