Ionic Storage and initial data loading / local data

Hey,

I am using the Ionic storage with a provider.

If my storage is empty (i.e. first time app starts), I would like to populate it with initially stored data from my Ionic storage.

What is the best approach for that?

I was thinking to perform something like this:

StorageProvider.ts:

  initData(){
    return new Promise(resolve => {
      this.storage.set(this.storageKey, [some, dummy, data]);
      resolve(this.storage.get(this.storageKey));
      });
  }

  getStoredData(){
    return new Promise(resolve => {
      this.storage.get(this.storageKey).then((data) => {
        resolve(data);
      });
    })
  }

MainPage.ts:
  ionViewWillEnter() {
     this.myData = this.myDataProvider.getStoredData().then(data => {
       if (data == null) {
           this.myDataProvider.initData();
           return (this.myDataProvider.getStoredData().then(data => data));
        } else {
          return data;
       }
    }

Any issues with that?

Other than that, should I fetch the data from a simple variable (i.e. array object), or should I make a http.get on a locally stored json file?

Thanks in advance!
