Expo SDK and React Native: Compatibility considerations for third‑party native modules
When developing with Expo, the SDK pins a specific React Native version, and all expo‑* modules are compiled against that RN release. This creates an integration boundary between the Expo SDK and the React Native runtime that third‑party native libraries must also respect. Developers often need to add native code that is not part of the Expo SDK, and they mu
expoHermes bytecode cache invalidation during React Native development-to-production migration
Hermes Bytecode Cache Invalidation During Migration When migrating a small React Native application to production with Hermes enabled, the transition from development to production builds requires careful handling of the bytecode cache. The Hermes engine compiles JavaScript to platform-specific bytecode (.hbc files), which provides significant bundle size re
Fabric and TurboModules New Architecture opt-in leaves legacy bridge deprecation timeline unresolved
React Native projects can enable Fabric renderer and TurboModules via configuration, which changes native module loading semantics compared with the legacy Paper renderer and bridge. The framework continues to maintain both code paths, and recent releases have shifted Hermes to default while New Architecture remains opt-in. This creates a compatibility bound
