The state read-only property of the RemotePlayback interface returns the current state of the RemotePlayback connection.

One of:

"connecting"

The user agent is attempting to initiate remote playback with the selected device.

"connected"

The transition from local to remote playback has happened. All commands will now take place on the remote device.

"disconnected"

The remote playback has not been initiated, has failed to initiate, or has been stopped.

In the following example the value of RemotePlayback.state is printed to the console when the user agent successfully connects.

RemotePlayback.onconnect = () => {
  console.log(RemotePlayback.state);
};
