CI-CD

name: "CI-CD" description: "Automate builds, tests, and deployments across web, mobile, and backend applications."

When to Use

Trigger on: automated deployment, continuous integration, pipeline setup, GitHub Actions, GitLab CI, build failing, deploy automatically, CI configuration, release automation.

Platform Selection

Decision tree: If platform handles deploy automatically (Vercel, Netlify) → skip custom CI. Only add GitHub Actions when you need tests, custom builds, or deploy to your own infra.

Quick Start Templates

For copy-paste workflows, see templates.md.

Common Pipeline Pitfalls

Mobile-Specific: Code Signing

The #1 pain point. iOS requires certificates + provisioning profiles. Android requires keystores.

The fix: Use Fastlane Match — stores certs/profiles in git repo, syncs across team and CI.

# One-time setup
fastlane match init
fastlane match appstore

# In CI
fastlane match appstore --readonly

For detailed mobile CI/CD patterns (iOS, Android, Flutter), see mobile.md.

Web-Specific: Build Caching

Next.js/Nuxt builds are slow without cache. The No Cache Detected warning = full rebuild.

# GitHub Actions: persist Next.js cache
- uses: actions/cache@v4
  with:
    path: .next/cache
    key: nextjs-${{ hashFiles('**/package-lock.json') }}

For framework-specific configs, see web.md.
