MediaSession not supported by TypeScript 2.3.4

TypeScript Version: 2.3.4

Code

  navigator.mediaSession.metadata = new MediaMetadata({
    title: "Podcast Episode Title",
    artist: "Podcast Host",
    album: "Podcast Name",
    artwork: [{src: "podcast.jpg"}]
  });
  navigator.mediaSession.setActionHandler('play', function() {});
  navigator.mediaSession.setActionHandler('pause', function() {});
  navigator.mediaSession.setActionHandler('seekbackward', function() {});
  navigator.mediaSession.setActionHandler('seekforward', function() {});
  navigator.mediaSession.setActionHandler('previoustrack', function() {});
  navigator.mediaSession.setActionHandler('nexttrack', function() {});
}

Expected behavior: MediaSession and MediaMetadata should be recognized by Typescript.

https://developer.mozilla.org/en-US/docs/Web/API/MediaSession https://developers.google.com/web/updates/2017/02/media-session

Actual behavior: Visual Studio Code Version 1.17.2 is showing the following Problems after saving the ts file:

message: ‘Property ‘mediaSession’ does not exist on type ‘Navigator’.’ message: ‘Cannot find name ‘MediaMetadata’.’

As a workround I have installed @types/wicg-mediasession: https://www.npmjs.com/package/@types/wicg-mediasession

The “solution” is not // @ts-ignore but installing @types/wicg-mediasession as stated by @pablo-gonzalez

npm install --save-dev @types/wicg-mediasession

I’m using it now and it’s working fantastic!
