The Death of the React Native Bridge: Moving from JSON to JSI in 2026
React Native is transitioning from its legacy JSON Bridge to a new JavaScript Interface (JSI) by 2026. This change aims to improve performance by allowing direct memory references and eliminating JSON serialization delays. The transition began in March 2022 and will be fully implemented by April 2026, marking a significant architectural shift in React Native development.
- ▪The React Native Bridge facilitates communication between JavaScript and native threads.

- ▪By April 2026, the legacy bridge will be completely removed from the codebase.
