MediaSession: metadata property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The metadata property of the MediaSession interface contains a MediaMetadata object providing descriptive information about the currently playing media, or null if the metadata has not been set. This metadata is provided by the browser to the device for presentation in any standard media control user interface the device might offer.

Value

An instance of MediaMetadata containing information about the media currently being played.

Example

The following example checks for compatibility and creates a new media session with the relevant metadata:

js
if ("mediaSession" in navigator) {
  navigator.mediaSession.metadata = new MediaMetadata({
    title: "Unforgettable",
    artist: "Nat King Cole",
    album: "The Ultimate Collection (Remastered)",
    artwork: [
      {
        src: "https://dummyimage.com/96x96",
        sizes: "96x96",
        type: "image/png",
      },
      {
        src: "https://dummyimage.com/128x128",
        sizes: "128x128",
        type: "image/png",
      },
      {
        src: "https://dummyimage.com/192x192",
        sizes: "192x192",
        type: "image/png",
      },
      {
        src: "https://dummyimage.com/256x256",
        sizes: "256x256",
        type: "image/png",
      },
      {
        src: "https://dummyimage.com/384x384",
        sizes: "384x384",
        type: "image/png",
      },
      {
        src: "https://dummyimage.com/512x512",
        sizes: "512x512",
        type: "image/png",
      },
    ],
  });
}
