Trying to use IonicStorageModule, not resolving methods

Ionic Framework ionic-v3
1

I just updated to latest Ionic 2.2.0 and local Storage stopped working - so I’m attempting to move everything to using IonicStorageModule. I have followed the instructions at https://github.com/driftyco/ionic-storage/releases/tag/v2.0.0 but the methods get, set, remove, etc. are all reporting that they don’t exist.

In my modules I do stuff like:

import { IonicStorageModule } from '@ionic/storage';

constructor(public navCtrl: NavController, 
              public local_storage: IonicStorageModule) {}

someCode () {
   this.local_storage.set('login_user', email).then(() => {...
}

The errors I see are similar to:

[12:22:16]  typescript: src/pages/login/login.ts, line: 251 
            Property 'set' does not exist on type 'IonicStorageModule'.

Any recommendations? Thanks in advance.

IonicStorageModule is only for importing into your app module. When using it, one just injects the Storage provider, not the module.

Thanks. I was there originally. Went back to that - and now I’m seeing:

Can't resolve all parameters for Storage: (?).

The stack looks like:

Please double-check that you actually did follow all the instructions in the link you mentioned in your first post. Specifically, make sure that you took Storage out of your AppModule’s providers.

Yes, followed those instructions.

My imports:

 imports: [
    IonicModule.forRoot(MyApp),
    AngularFireModule.initializeApp (firebaseConfig, authConfig),
    IonicStorageModule.forRoot()
  ],

My providers:

  providers: [{provide: ErrorHandler, useClass: IonicErrorHandler}, 
              {provide: Globals, useClass: Globals}, 
              {provide: ActivityTracker, useClass: ActivityTracker}]

Where I’m using Storage (such as in my login.ts module) I import it as:

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

Is it possible you’re declaring Storage in a providers array of some other module or component? I just tried this with a scratch project and everything worked fine. If I add Storage to the providers array of the app module, I see the same error you are encountering.

Thank you. I did discover a buried provider referencing Storage - and removed it. Now to fix an ion-split-panel issue… which I just discovered is now called ion-split-pane… :wink:
