React Native Threads

Overview:

The react-native-threads package allows developers to spawn new React Native JavaScript processes for CPU intensive work outside of the main UI JavaScript process. It provides a form of multi-processing rather than true threading. Users should be mindful of the potential memory usage overhead when using this library and should benchmark their app's resource consumption beforehand. Alternative solutions like runAfterInteractions or Interaction Manager should be considered as well.

Features:

• Spawn New Processes: Allows for the creation of new JavaScript processes.
• CPU-Intensive Work: Ideal for handling CPU-intensive tasks separately from the main UI thread.
• Multi-Processing: Offers a multi-processing solution instead of traditional threading.
• Memory Usage Consideration: Users need to be aware of potential memory overhead when creating new JS processes.

Getting Started:

$ npm install react-native-threads --save

Mostly Automatic Installation:

$ react-native link react-native-threads

Android:

1. Modify MainApplication.java:

   new RNThreadPackage(mReactNativeHost, new ExampleNativePackage(), new SQLitePackage())
   

Manual Installation for iOS:

1. Add RNThread.xcodeproj to XCode.
2. Add libRNThread.a to project's Build Phases.
3. Run the project.

Manual Installation for Android:

1. Add to MainApplication.java:

   new RNThreadPackage(mReactNativeHost, new ExampleNativePackage(), new SQLitePackage())
   

2. Add the necessary lines to settings.gradle and app/build.gradle.

Windows:

• Windows support is not yet implemented.
• Contributions are welcome for implementing Windows support.

Summary:

The react-native-threads package offers a way to separate CPU-intensive tasks into new JavaScript processes in React Native, providing a multi-processing solution. Users should carefully evaluate the memory overhead and potential trade-offs before integrating this package into their projects. Alternative solutions should also be explored to determine the best approach for handling intensive tasks in React Native applications.
