“DefaultRootState”类型中缺少属性“X”-但该属性是在接口中声明的

Question

Here's my Interface which I'm using with mapStateToProps :

export interface IStore {
  cache?: any;
  dataManager?: IUR;
  userPrefs: IUP;
  IModal?: IfingerprintModal;
}

export interface IModal {
  cbCancel: IFModalFn | null;
  cbTryAgain?: IFModalFn | null;
  error: null | string;
  success: boolean;
  visible: boolean;
}

Here's the mapStateToProps fn expression:

const mapStateToProps = (state: IStore) => ({
  store: {
    IModal: state.userPrefs.IModal,
  },
});

And here's the connect HOC:

export default connect<IStore,{}>(mapStateToProps, mapDispatchToProps)(IModal);

That's the error I'm seeing:

I can get rid of the problem by:

export default connect<IStore>(mapStateToProps as any, mapDispatchToProps)(IModal);

But I am trying to find a generic solution to that

Answer 1

Just remove the type from the connect call and let typescript to handle it for you:

connect(mapStateToProps, mapDispatchToProps)(FingerprintModal);

Otherwise you would need to specify the full type:

connect<{store: IStore;}, {}, {}, IStore>(mapStateToProps, mapDispatchToProps)
