ng2-auto-save v0.0.2

ng2-auto-save

still in development

Purpose of this module is to provide an angular2 directive, which is able to save user input to the Local Storage automatically, and reload it, if something happens to the current page. The save is triggered on the user keyup-event, and debounced to save on resources. The user must provide a unique identifier for their content.

Later I'll try to provide a way to configure, so you can save to Session storage, if it's sensitive data. Also users should have control over what data they want to remove. Now you do this manually by tinkering with LocalStorage.

example

This textbox content should survive page reload, browser close, etc...

<div> 
<textarea placeholder="{{hint}}"
          auto-save [(asdata)]="textData"
          (reloadData)="setText($event)"
          askey="unique127"
          [(ngModel)]="textData"></textarea>
</div>

Parameter description:

auto-save: directive itself, accepts 2 parameters as @Input, and one @Output

askey: @Input, needs to be a unique key, otherwise overwrites could happen.

asdata: @Input, should be the model you keep modifying by the component

reloadData: @Output, handler function to restore your data after viewInit
