react-native-nitro-template

This is a template for Nitro Modules.

Usage

Clone this repo, and change all $$*$$ names according to your nitro.json file.

Contributing

Contribute a change to this template to update it for newer React Native versions.

Structure

• android/: All your android-specific implementations.
  • build.gradle: The gradle build file. This contains four important pieces:
    1. Standard react-native library boilerplate code
    2. Configures Kotlin (apply plugin: 'org.jetbrains.kotlin.android')
    3. Adds all Nitrogen files (apply from: '.../NitroMath+autolinking.gradle')
    4. Triggers the native C++ build (via CMake/externalNativeBuild)
  • CMakeLists.txt: The CMake build file to build C++ code. This contains four important pieces:
    1. Creates a library called NitroMath (same as in nitro.json)
    2. Adds all Nitrogen files (include(.../NitroMath+autolinking.cmake))
    3. Adds all custom C++ files (only HybridTestObjectCpp.cpp)
    4. Adds a cpp-adapter.cpp file, which autolinks all C++ HybridObjects (only HybridTestObjectCpp)
  • src/main/java/com/margelo/nitro/math/: All Kotlin implementations.
    • NitroMathPackage.java: The react-native package. You need this because the react-native CLI only adds libraries if they have a *Package.java file. In here, you can autolink all Kotlin HybridObjects.
• cpp/: All your cross-platform implementations. (only HybridTestObjectCpp.cpp)
• ios/: All your iOS-specific implementations.
• nitrogen/: All files generated by nitrogen. You should commit this folder to git.
• src/: The TypeScript codebase. This defines all HybridObjects and loads them at runtime.
  • specs/: All HybridObject types. Nitrogen will run on all *.nitro.ts files.
• nitro.json: The configuration file for nitrogen. This will define all native namespaces, as well as the library name.
• NitroMath.podspec: The iOS podspec build file to build the iOS code. This contains three important pieces:
  1. Specifies the Pod's name. This must be identical to the name specified in nitro.json.
  2. Adds all of your .swift or .cpp files (implementations).
  3. Adds all Nitrogen files (add_nitrogen_files(s))
• package.json: The npm package.json file. react-native-nitro-modules should be a peerDependency.
