RTCDataChannel: negotiated property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The read-only RTCDataChannel property negotiated indicates whether the RTCDataChannel's connection was negotiated by the Web app (true) or by the WebRTC layer (false). The default is false.
See Creating a data channel for further information about this property.
Value
true if the RTCDataChannel's connection was negotiated by the Web app itself; false if the negotiation was handled by the WebRTC layer. The default is false.
Example
The code snippet below checks the value of negotiated; if it's true, a function called shutdownRemoteChannel() is called with the channel's id; presumably this would be implemented to transmit a shutdown signal to the remote peer prior to terminating the connection.
if (dataChannel.negotiated) { shutdownRemoteChannel(dataChannel.id); } Specifications
