Automate lint, test, and deploy for React and Next.js—GitHub Actions, Vercel, and quality gates.
CI/CD keeps frontend quality high and deploys predictable. Here’s how to set it up for React and Next.js.
CI/CD and frontend pipelines
Pipeline steps
Lint — ESLint (and Prettier if you run it in CI). Fail the build on errors; fix or relax rules consciously.
Test — Unit and integration tests (Jest, Vitest, RTL). Run on every PR. Collect coverage; gate on threshold if you want.
Build — npm run build. Catch build failures and dependency issues before merge. Cache node_modules and build output for speed.
Deploy — Vercel, Netlify, or your own: trigger on push to main (or a release branch). Use preview deployments for PRs when possible.
CI usage (frontend teams):
CI steps in frontend pipelines
GitHub Actions example
One workflow: on push/PR, checkout, setup Node, cache deps, install, lint, test, build. Use matrix for multiple Node versions if needed. Deploy step: call Vercel/Netlify API or use their GitHub integration.

Takeaway
Automate lint, test, and build in CI. Use preview deployments for PRs. Keep the pipeline fast so the team doesn’t bypass it. Add E2E when you have critical flows to protect.
