Summary: The PlatformConstants native module exposes the ability to query the React Native version used to build native code. This is managed on iOS and Android by a version bumping script, which replaces module code based on a template. It is currently difficult to accurately determine this version for out-of-tree C++ platforms (I.e. React Native Windows). The version of upstream react-native we resolve to is ultimately dependent on the version of react-native chosen a peer dependency, which is not neccesarily constant given a build of react-native-windows. We could try to hack around this, and make our native build try to reason about the resolved pacakge for react-native using a lockfile, but a much cleaner solution is to embed version into C++ code, similar to what is done for Android and iOS. This change does that, adding a header with React Native version and updating the build stamping script to write to it. Usage sample: ```c++ constants["reactNativeVersion"] = folly::dynamic::object(); constants["reactNativeVersion"]["major"] = ReactNativeVersion.Major; constants["reactNativeVersion"]["minor"] = ReactNativeVersion.Minor; constants["reactNativeVersion"]["patch"] = ReactNativeVersion.Patch; ``` ## Changelog [General] [Added] - Stamp React Native Version Into C++ Code Pull Request resolved: https://github.com/facebook/react-native/pull/28036 Test Plan: Validated that the bumping script will accurately update the header, can compile under both MSVC and Clang.
