How does React Native bridge work?
Updated May 6, 2026
Short answer
The bridge connects JavaScript code with native platform modules.
Deep explanation
React Native uses an asynchronous bridge to communicate between JavaScript and native threads. JS sends serialized messages to native modules, which execute platform-specific logic and return results. This architecture allows cross-platform development but can introduce performance overhead.
Real-world example
Accessing camera or GPS via native modules.
Common mistakes
- Overusing bridge calls causing performance bottlenecks.
