Mobile at Scale with React Native & Multi-Module Architecture
summary
Wix runs a single React Native app that ~80 mobile developers across ~20 teams ship to stores daily by separating an Engine (native APK/App build, shared infrastructure) from independently developed feature Modules that expose a model.js contract. CI (TeamCity) publishes models to an internal NPM, RC/GA tags trigger full app builds, distribution via HockeyApp/AppCenter and TestFlight/Play, and E2E tests use Espresso + EarlGrey. Claim: ~80% code reuse across iOS/Android; main pain is the React Native bridge performance.
