@ngx-extensions/screenfull v0.1.0

@ngx-extensions/screenfull

A simple wrapper around screenfull.js for Angular.

Installation

npm install @ngx-extensions/screenfull

Setup

Import NgxScreenfullModule into your module

import { NgxScreenfullModule } from '@ngx-extensions/screenfull';

@NgModule({
 imports: [NgxScreenfullModule]
})
export class AppModule {}

Usage

The most basic use case is to toggle the fullscreen mode through an element´s click event:

<button ngxToggleFullscreen>Toggle fullscreen</button>

Note: the host element of ngxToggleFullscreen does not necessarily have to be a <button>

The state of the fullscreen mode can be tracked through the ScreenfullService

import { ScreenfullService } from '@ngx-extensions/screenfull';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

@Component({
 template: `
    <span>Screenfull mode is currently {{ mode$ | async }}</span>
  `
})
export class DemoComponent {
 readonly mode$: Observable<string>;

 constructor(public readonly screenfullService: ScreenfullService) {
  this.mode$ = this.screenfullService.fullScreenActive$.pipe(
   map(active => (active ? 'active' : 'inactive'))
  );
 }
}

To interact with the fullscreen API, use the ScreenfullService:

import { ScreenfullService } from '@ngx-extensions/screenfull';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

@Component({
 template: `
    <button (click)="screenfullService.request()">Enter fullscreen</button>
    <button (click)="screenfullService.exit()">Exit fullscreen</button>
    <button (click)="screenfullService.toggle()">Toggle fullscreen</button>
    <span>Screenfull mode is currently: {{ mode$ | async }}</span>
  `
})
export class DemoComponent {
 readonly mode$: Observable<string>;

 constructor(public readonly screenfullService: ScreenfullService) {
  this.mode$ = this.screenfullService.fullScreenActive$.pipe(
   map(active => (active ? 'active' : 'inactive'))
  );
 }
}
