React Turbo Native Modules

Turbo Modules is a project by Facebook that aims to improve the performance of native modules in React Native by using a new architecture.


In React Native, native modules are modules written in native languages (like Java or Objective-C) that can be accessed from JavaScript.

 

Turbo Modules optimize the communication between JavaScript and native modules, making it faster and more efficient.

Turbo Modules introduces a new runtime layer called the Turbo Runtime which is designed to reduce the overhead of method calls between JavaScript and native code. This can improve the significant performance of React Native apps, especially for scenarios involving frequent communication between JavaScript and native modules.

 

In React Native, native modules are pieces of code written in the platform's native language (Java/Kotlin for Android, Objective-C/Swift for iOS) that can be called from JavaScript.

 

If you have an idea about React Native, you may be familiar with the concept of Native Modules, which allow JavaScript and platform-native code to communicate over the React Native "bridge", which handles cross-platform serialization via JSON.

 

A few Benefits of Turbo Native Modules,

  • Allowing for faster app startup
  • Lazy loading of modules
  • Strongly typed interfaces
  • Turbo Native Modules reduce duplicate implementations across platforms

 

How to Create a Turbo Native Module?

To create a Turbo Native Module, we need to:

  •  Firstly, we need to define the JavaScript specification
  • After that configure the module so that Codegen can generate the scaffolding
  • In the last, write the native code to finish implementing the module
