CI/CD for React Native Apps

A solid CI/CD pipeline catches bugs before release and keeps builds reproducible. For React Native and Expo, here’s a minimal setup that scales.

What to Run on Every PR

Lint (ESLint, TypeScript), unit tests, and (if feasible) a subset of E2E tests. For Expo, add expo doctor and dependency checks. Fail the pipeline on lint or test failures so broken code doesn’t reach main.

Build and Submit in CI

Use EAS Build in your CI (e.g. GitHub Actions) to build iOS and Android on every release. EAS Submit can push to TestFlight and internal testing tracks. Avoid building only on a single developer’s machine; CI builds are consistent and auditable.

OTA Updates and Versioning

With EAS Update, ship JS and asset changes without store review. In CI, tag releases and trigger updates for the appropriate channels. Keep version and build numbers in sync so you can map a user’s app to a specific build and update.

Investing in CI/CD early reduces release stress and makes it easier to ship often and safely.
