Why We Stopped Using JSON.parse in React Native
SMRTR summary
When parsing a ~250 MB JSON bundle in React Native, JSON.parse caused multi-second freezes on iOS and outright crashes on Android. Switching to react-native-fast-json, which wraps simdjson for native parsing, reduced parse time to ~100ms on iOS and ~500ms on Android with stable memory. The guide covers installation, the lazy JsonView API, and memory management patterns like short-lived roots and explicit cache release.
