Module Platform.Initialization

1. create ServerInitializationExtension on server.
2. create InitializationExtension on client:

@extension()
export class MyInitializationExtension extends InitializationExtension {
  constructor(
    @inject(IInitializationRepository$) private readonly _repository: IInitializationRepository
  ) {
    super();
  }

  override async afterRequest(context: IInitializationExtensionContext): Promise<void> {
    const additionalData = StorageHelper.tryGet(context.response?.tryGetInfo(), 'MyAdditionalData');
    if (!additionalTiles) {
      return;
    }

    await this._repository.setIfNotExists('MyAdditionalData', additionalData);
  }
}

3. get data from IInitializationRepository:

@extension()
export class MyCardUIExtension extends CardUIExtension {
  constructor(
    @inject(IInitializationRepository$) private readonly _repository: IInitializationRepository
  ) {
    super();
  }

  override async initialized(context: ICardUIExtensionContext): Promise<void> {
    const data = await this._repository.tryGet('MyAdditionalData');
    // ...
  }
}
