Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/35265 This adds a templating layer for C++ TurboModules to automatically generate struct templates from TurboModule specs. You have to define concrete types for those templates to use them in your C++ TurboModule. E.g. for the JS flow type: ``` export type ObjectStruct = {| a: number, b: string, c?: ?string, |}; ``` code-gen will now generate the following template code: ``` #pragma mark - NativeCxxModuleExampleCxxBaseObjectStruct template <typename P0, typename P1, typename P2> struct NativeCxxModuleExampleCxxBaseObjectStruct { P0 a; P1 b; P2 c; bool operator==(const NativeCxxModuleExampleCxxBaseObjectStruct &other) const { return a == other.a && b == other.b && c == other.c; } }; template <typename P0, typename P1, typename P2> struct NativeCxxModuleExampleCxxBaseObjectStructBridging { static NativeCxxModuleExampleCxxBaseObjectStruct<P0, P1, P2> fromJs( jsi::Runtime &rt, const jsi::Object &value, const std::shared_ptr<CallInvoker> &jsInvoker) { NativeCxxModuleExampleCxxBaseObjectStruct<P0, P1, P2> result{ bridging::fromJs<P0>(rt, value.getProperty(rt, "a"), jsInvoker), bridging::fromJs<P1>(rt, value.getProperty(rt, "b"), jsInvoker), bridging::fromJs<P2>(rt, value.getProperty(rt, "c"), jsInvoker)}; return result; } static jsi::Object toJs( jsi::Runtime &rt, const NativeCxxModuleExampleCxxBaseObjectStruct<P0, P1, P2> &value) { auto result = facebook::jsi::Object(rt); result.setProperty(rt, "a", bridging::toJs(rt, value.a)); result.setProperty(rt, "b", bridging::toJs(rt, value.b)); if (value.c) { result.setProperty(rt, "c", bridging::toJs(rt, value.c.value())); } return result; } }; ``` and you can use it in our C++ TurboModule for example as: ``` using ObjectStruct = NativeCxxModuleExampleCxxBaseObjectStruct< int32_t, std::string, std::optional<std::string>>; template <> struct Bridging<ObjectStruct> : NativeCxxModuleExampleCxxBaseObjectStructBridging< int32_t, std::string, std::optional<std::string>> {}; ``` or as ``` using ObjectStruct = NativeCxxModuleExampleCxxBaseObjectStruct< float, folly::StringPiece, std::optional<std::string>>; template <> struct Bridging<ObjectStruct> : NativeCxxModuleExampleCxxBaseObjectStructBridging< float, folly::StringPiece, std::optional<std::string>> {}; ``` Or as ...
