Codegen chokes on imported types

[birdofpreyru]

Description

It seems codegen currently chokes on types imported from a different module, i.e. consider this example:

// types.ts
export type MyType = {
  field: string;
};

// NativeReactNativeMyModule.ts
import type { TurboModule } from 'react-native';
import { TurboModuleRegistry } from 'react-native';

import { type MyType } from './types';

export interface Spec extends TurboModule {
  myMethod(arg: MyType): void;
}

export default TurboModuleRegistry.getEnforcing<Spec>('ReactNativeMyModule');

When running the build (for Android on Ubuntu system) the codegen chokes on the method definition saying UnsupportedGenericParserError: Module NativeReactNativeMyModule: Unrecognized generic type 'MyType' in NativeModule spec.

This equivalent code works fine though:

import type { TurboModule } from 'react-native';
import { TurboModuleRegistry } from 'react-native';

export type MyType = {
  field: string;
};

export interface Spec extends TurboModule {
  myMethod(arg: MyType): void;
}

export default TurboModuleRegistry.getEnforcing<Spec>('ReactNativeMyModule');

Yes, that is a currently known limitation of codegen. The (very ugly) workaround is to copy-and-paste the types you need in the module definition.

We are currently working on solving this, so it will be hopefully available soon.
