Expo SDK 53: New Architecture Deep Dive

Explore the new architecture features in Expo SDK 53 and how they improve performance and developer experience in React Native apps.

What's new in Expo SDK 53?

Expo SDK 53 introduces the React Native New Architecture as default, bringing 2-3x faster startup times, synchronous native module calls via JSI, and improved memory management. It also includes updated native modules, better TypeScript support, and enhanced development tools. AI Mobile Launcher is built on Expo SDK 53 with full New Architecture support.

Expo SDK 53 represents a major leap forward for React Native development, with significant improvements in performance, developer experience, and compatibility.

What is the New Architecture in React Native?

The New Architecture provides better performance and more predictable behavior:

  • JSI (JavaScript Interface) - Direct communication between JS and native without bridge serialization
  • Fabric Renderer - Synchronous UI updates for smoother animations
  • TurboModules - Lazy-loaded native modules for faster startup
  • Codegen - Type-safe native code generation from TypeScript

How does Expo SDK 53 improve developer experience?

With faster build times, better error messages, and improved tooling, developing with Expo SDK 53 is more productive than ever.
