Description
While the closing event is sent to the channel just before beginning to close the channel's data transport, the close event is sent once the closing process is complete.
Examples
This example updates a connection status interface when the closing event arrives.
First, an example using addEventListener():
dataChannel.addEventListener("closing", ev => {
myConnectionStatus.icon = closingIcon;
myConnectionStatus.text = "Connection closing";
});You can also set the onclosing event handler property directly:
pc.onclosing = ev => {
myConnectionStatus.icon = closingIcon;
myConnectionStatus.text = "Connection closing";
