Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/44630 Changelog: [General][Breaking] Use hasteModuleName for C++ Turbo Module structs This changes the names of C++ Turbo Modules structs to use the `hasteModuleName`. Example: `NativeMyAbcModule.js` with this spec: ``` export type ValueStruct = { x: number, y: string, z: ObjectStruct, }; export interface Spec extends TurboModule { +getValueStruct: () => ValueStruct } export default (TurboModuleRegistry.get<Spec>('MyAbcModuleCxx'): ?Spec); ``` Before now we generated a base C++ struct with the name: ``` MyAbcModuleCxxValueStruct ^^^ ``` Now the generate name is: ``` NativeMyAbcModuleValueStruct ^^^^^^ ``` ## Changes: - No `Cxx` injected anymore - Ensure base struct is `Native` prefixed (all RN JS TM specs start with it) ## Why? - The `Cxx` extension is a temporary hint to react-native-codegen to enable extra capabilities and might disappear eventually - The C++ base struct name should be 'stable' - The name of the exported TM JS spec `TurboModuleRegistry.get<Spec>(...)` is abritrary, the hasteName is not - The name of the RN JS TM spec must start with `Native` which better guarantees a consistent naming scheme for these generated base class - The C++ Turbo Module base class has now the same prefix as the generated structs - `NativeMyAbcModule` for the example above Reviewed By: cipolleschi Differential Revision: D57599257 fbshipit-source-id: 4fafe6c7e920737fa766bd7e8e68e521f608e775
