LocalStorage
The LocalStorage storage engine uses the browser's local storage system for storing key/value pairs.
Note: LocalStorage should ONLY be used for temporary data that you can afford to lose. Given disk space constraints on a mobile device, local storage might be "cleaned up" by the operating system (iOS).
For guaranteed, long-term storage, use the SqlStorage engine which stores data in a file.
Usage
import {Page, Storage, LocalStorage} from 'ionic-angular';
@Page({
template: `<ion-content></ion-content>`
});
export class MyClass{
constructor(){
this.local = new Storage(LocalStorage);
this.local.set('didTutorial', 'true');
}
}
