Flipadelphia
A customizable feature toggle library with an angular component UI.
Setup:
Instantiate extend Flipadelphia and addd toggles like below:
import { Flip, Flipadelphia } from './flipadelphia';
export class MyFeatureToggles extends Flipadelphia {
@Flip() foo: boolean;
@Flip(true) bar: boolean;
@Flip(true, 'This toggle is for bah') bah: boolean;
constructor() {
super();
}
}
You may also pass an adapter that implements the provided FlipperService interface to the Flipadelphia base constructor.
import { Flip, Flipadelphia, LocalStorageFlipperService } from './flipadelphia';
export class MyFeatureToggles extends Flipadelphia {
@Flip() foo: boolean;
constructor() {
super(new LocalStorageFlipperService('CustomKey'));
}
}
Then use the getters on an instance of your toggle class:
const myToggles = new MyFeatureToggles();
expect(myToggles.foo).toBe(false);
If you use angular you may want to consider setting up as a provider for DI.
If you would like to update a toggle w/o the UI you can add your custom key or the default "FLIPADELPIA" to local storage with a value of
{"toggleName": booleanState}
For the UI:
- Import FlipadelphiaModule into your module
- Add the flipadelphia component to your site somewhere and provide your Flipadelphia extended class as an input
<flipadelphia flipadelphiaInstance="youToggles"></flipadelphia>
