React Native MicroApp Architecture
summary
Claim: splitting a monolithic React Native app into a core application (native libs, debug APKs, routing via react-navigation) plus JavaScript-only micro apps (npm packages with a microwave.js contract) reduces cold start on iOS from >1 minute to <10 seconds and unit-test runs from ~350s to ~50s. Micro apps contain no native code, export methods/stacks through the core, use peer dependencies for versioning, run Jest and React Native Testing Library, and assemble into a buildable main app for independent deployment.
