The Evolution: Why the Bridge is Dead

React Native 2026: Bridgeless Architecture & JSI

The Evolution of React Native

For years, React Native relied on a Bridge to communicate between JavaScript and Native (Java/Objective-C). This bridge used asynchronous JSON serialization, which caused performance bottlenecks.

The Problem with the Bridge:

  1. Asynchronous: You couldn't get a value back from native code instantly.
  2. Serialized: Every piece of data had to be converted to JSON strings.
  3. Single Channel: High-priority UI updates shared the same queue as low-priority background tasks.

In this lesson, we explore how the 2026 architecture replaces this with JSI, allowing direct pointer-based communication.
