Callstack's Bridgeless Architecture in React Native Development
Original post Bridgeless Architecture in React Native Development
Article Summary
The React Native Bridge has been the performance bottleneck we've all learned to work around. Now it's finally going away.
Callstack explores the shift to Bridgeless Architecture in React Native, a fundamental change that eliminates the asynchronous bridge between JavaScript and native code. This architectural evolution promises to unlock significant performance gains and simplify the communication layer that's been a constraint since React Native's inception.
Key Takeaways
- Bridgeless mode removes the async bridge between JavaScript and native threads
- Direct synchronous communication replaces serialized message passing
- TurboModules and Fabric renderer enable the new architecture
- Migration requires updating native modules to support the new system
Bridgeless Architecture fundamentally rewrites how React Native communicates between JavaScript and native code, eliminating a major performance bottleneck.

What This Article Covers
React Native developers have dealt with the asynchronous bridge creating serialization overhead and latency between JavaScript and native threads. This limits how responsive mobile applications can be in real time.
TurboModules and Fabric renderer let JavaScript call native code directly without the delays that come from message serialization. Callstack explains how this synchronous communication works.
The Bridgeless Architecture removes the async bottleneck that has slowed React Native since the beginning. Native modules execute faster and user interactions feel smoother.
