How can I load all data from SQlite database? (Ionic 3, Angular 5, Cordova)

How can I load all data stored in sqlite storage at a time?

I have several data objects with different keys and id values.

I want to load them all on a single list using *ngFor directive.

<div *ngFor="let item of items">
   <h1>{{ item.name }}</h1>
<p> {{ item.about }} </p>
</div>

and here's my home ts file for that:

  ionViewDidLoad() {

      this.storage.get(item);

  }

this code will not work obviously. I know how to get a single data object using this this get() method but I don't know how to load everything at a time.

Please help.

Thanks,

Solution

  • IonicNative Storage wrapper exposes a forEach method.

    This method will return all the key: value pairs

    this.storage.forEach((value, key, iterationNumber) => {
   // here you can do whatever you want to do with all the data.
});
