RTCPeerConnection: pendingRemoteDescription property

The pendingRemoteDescription read-only property of the RTCPeerConnection interface returns an RTCSessionDescription object describing a pending configuration change for the remote end of the connection.

This does not describe the connection as it currently stands, but as it may exist in the near future. Use RTCPeerConnection.currentRemoteDescription or RTCPeerConnection.remoteDescription to get the current session description for the remote endpoint. For details on the difference, see Pending and current descriptions in the WebRTC Connectivity page.


If a remote description change is in progress, this is an RTCSessionDescription describing the proposed configuration. Otherwise, this returns null.


This example looks at the pendingRemoteDescription to determine whether or not there's a description change being processed.

const pc = new RTCPeerConnection();
// ...
const sd = pc.pendingRemoteDescription;
if (sd) {
  // There's a description change underway!
} else {
  // No description change pending

Note: The addition of pendingRemoteDescription and currentRemoteDescription to the WebRTC spec is relatively recent. In browsers which don't support them, only remoteDescription is available.
