Expo and EAS: Ship React Native to Production with Confidence

Expo accelerates development with managed tooling and over-the-air updates for compatible changes. EAS Build and Submit reduce the toil of signing, credentials, and store pipelines—especially for teams without dedicated mobile release engineers.

When Expo fits

Greenfield products, startups, and teams prioritizing velocity often standardize on Expo. If you need custom native code, Expo supports config plugins and prebuild workflows to sync with bare projects.

EAS Build and environments

Define profiles for development, preview, and production. Store secrets in EAS and map environment variables per channel. Keep runtime config separate from build-time secrets.

Updates and compliance

OTA updates are powerful; follow Apple and Google policies for what may change without store review. Communicate breaking API changes through versioning and feature flags.

Next steps

Read EAS documentation for the latest limits, pricing, and integration with CI. Plan migration paths before you outgrow defaults.
