      This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The RTCDataChannelEvent interface
represents an event related to a specific RTCDataChannel.
Constructor
- RTCDataChannelEvent()
- 
Creates a new RTCDataChannelEvent.
Instance properties
Also inherits properties from Event.
- channelRead only
- 
Returns the RTCDataChannelassociated with the event.
Examples
In this example, the datachannel event handler is set up to save the data channel reference and set up handlers for the events which need to be monitored. The channel property provides the RTCDataChannel representing the connection to the other peer.
js
pc.ondatachannel = (event) => {
  inboundDataChannel = event.channel;
  inboundDataChannel.onmessage = handleIncomingMessage;
  inboundDataChannel.onopen = handleChannelOpen;
  inboundDataChannel.onclose = handleChannelClose;
};
See A simple RTCDataChannel sample for another, more complete, example of how to use data channels.
