have you even checked the docs?

```auto
import { Storage } from '@ionic/storage';

```

```auto
constructor(public storage: Storage)

```

```auto
  setUserId() {
    this.storage.set('userId', this.userId);
  }

```

No it doesn’t. Your comment is a lie. That method doesn’t return anything, and if you used proper return type declarations instead of false comments, you would have gotten a build-time error informing you of this fact. Please read the TypeScript, Angular, and Ionic documentation thoroughly until you really understand the fundamental building blocks of web apps. You cannot become competent at this by simply copying random nonsense you see on the web and expecting reliable results.

I don’t intend it as a personal attack, but in order for other people in forums like this to be able to give you assistance in a productive manner, you need to build up core competence in your craft, assuming that you really have a passion for programming.
