How does Shopify changes & adapts to the new architecture changes in React Native?
summary
Shopify reports it still hasn’t moved to the new RN architecture and upgrades break things through dependency incompatibilities, platform-specific native code and build-tool changes, and hidden test regressions. Real incidents include reverting a webview update that failed only in background mode and fixing unit tests after a V8 promise change. Mitigations are regular small updates, modular app boundaries, end-to-end plus manual QA, a panda bot for dependency tracking, a homegrown screenshot test tool react-native-testify, and avoiding monolithic upgrade jumps.
