CI/CD Pipeline
Design commit, pull request, build, test, and deployment gates for enterprise delivery.
Key takeaways
- A CI/CD pipeline moves through install, static checks, tests, build, security, and deploy stages, giving fast feedback early and stronger assurance before production.
- Turborepo PR CI should run
turbo run lint typecheck test build --affectedwith full git history; release CI can run broader verification. - Pull requests need scoped changes, preview links, package owners, and documented migrations or operational risk.
- Match the release strategy to context: continuous preview, scheduled release, feature flags, hotfix, or rolling release with metric comparison.
- If engineers rerun CI without knowing why it failed, fix the pipeline and its logs, not only the code.
CI/CD is the quality control system for change. It should give fast feedback during development and stronger assurance before production.
Pipeline Stages
| Stage | Goal | Typical checks |
|---|---|---|
| Install | Reproducible dependencies | Lockfile, package manager, cache |
| Static checks | Catch cheap failures early | Format, lint, typecheck |
| Tests | Verify behavior | Unit, integration, e2e where relevant |
| Build | Produce deployable artifacts | App and package builds |
| Security | Reduce operational risk | Secret scan, dependency review, policy checks |
| Deploy | Release with traceability | Preview, staging, production |
For Turborepo monorepos, PR CI should usually run turbo run lint typecheck test build --affected
with full git history available. Release CI can still run broader verification before production.
Pull Request Rules
- Keep changes scoped enough for meaningful review.
- Attach preview links for user-facing changes.
- Require owners for affected packages or apps.
- Document migrations, environment changes, and operational risk.
- Do not merge when required checks are skipped without explanation.
Release Strategy
| Strategy | Use when |
|---|---|
| Continuous preview | Most product changes |
| Scheduled production release | High coordination or enterprise customer impact |
| Feature flag rollout | Behavior needs staged exposure |
| Hotfix | Production incident or urgent regression |
| Rolling release | Deployment risk needs staged exposure and metric comparison |
Failure Handling
Pipeline failures should produce actionable logs. If engineers regularly rerun CI without knowing why it failed, fix the pipeline, not only the code.
