Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/35138 Changelog: [General][Added] - Add a C++ only TurboModule example (for Android/iOS/macOS/Windows) react-native@0.69 introduced a new bridging layer to ease integration for pure C++ TurboModules using C++ std:: types directly instead of the lower level jsi:: types: https://github.com/facebook/react-native/tree/v0.69.0/ReactCommon/react/bridging This bridging layer can be used in JSI functions or more conveniently in C++ TurboModules. Here is a example of an C++ only TurboModule which will work on Android and iOS and macOS/Windows (using microsoft/react-native-macos|windows) only using flow/TypeScript and standard C++ types. C++ only TurboModules are very handy as they do not require to work with JSI APIs - instead std:: or custom C++ can by used.
