NITRO

Summary from the TLDR Web Dev newsletter

Nitro is a framework for developing high-performance native modules in React Native. It achieves this through hybrid objects, which are native objects implemented in C++, Swift, or Kotlin that provide direct access to native functionalities. Nitro uses a lightweight layer built on JSI and bridges directly to Swift and Kotlin while still prioritizing type safety and null-safety by using a code-generator to make sure that TypeScript specifications are the single source of truth for both JavaScript and native code.
