How to "refresh" *ngIf?

IMHO the cleanest way to do this is to make a shim for this library in a provider that does roughly this: class WaveSurfer { whenFinished(): Promise<void> { return new Promise((resolve) => { this.wavesurfer.on('finish', () => resolve()); }); } } class Page { isPlaying: boolean; constructor(private _surfer: WaveSurfer) { _surfer.whenFinished().then(() => this.isPlaying = false); } }
