RTCDataChannel.ordered

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The read-only RTCDataChannel property ordered indicates whether or not the data channel guarantees in-order delivery of messages; the default is true, which indicates that the data channel is indeed ordered. This is set when the RTCDataChannel is created, by setting the ordered property on the RTCDataChannelInit object passed as RTCPeerConnection.createDataChannel()'s options parameter.

Syntax

var ordered = aDataChannel.ordered;

A Boolean value which is true if in-order delivery is guaranteed and is otherwise false.

Example

var pc = new RTCPeerConnection();
var dc = pc.createDataChannel("my channel");

if (!dc.ordered) {
  // Handle unordered messaging
}
