CI/CD (Continuous Integration / Continuous Deployment)

CI/CD automates the process of testing and deploying your code. Continuous Integration automatically runs tests when you push code. Continuous Deployment automatically deploys passing code to production. For vibe coders, CI/CD means pushing to GitHub and having your app automatically tested and deployed — zero manual steps.

Example

You push code to GitHub. GitHub Actions automatically runs your test suite, checks for TypeScript errors, and runs the linter. If everything passes, Vercel automatically deploys the new version. You pushed code and walked away — CI/CD handled the rest.

CI/CD removes the manual work between writing code and shipping it. Push your code, and automation handles testing and deployment.

CI vs CD

Linting, type checks, testsBuild, deploy, notify

How CI/CD Works

Push Code → CI Runs Tests → Tests Pass? → CD Deploys → Live!
                              ↓ No
                        Fix Issues → Push Again

CI/CD for Vibe Coders

Many vibe coders use CI/CD without realizing it:

  • Vercel auto-deploy — Push to GitHub, site updates automatically
  • Preview deployments — Every PR gets a preview URL
  • Automatic rollback — If deployment fails, previous version stays live

Setting Up Basic CI/CD

  1. Connect GitHub to your hosting — Vercel, Netlify, or Railway
  2. Add a build command — Usually auto-detected
  3. Push code — Deployment happens automatically
  4. Add tests later — GitHub Actions can run tests before deploy
