RTCDataChannel: maxRetransmits 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 maxRetransmits returns the maximum number of times the browser should try to retransmit a message before giving up, as set when the data channel was created, or null, which indicates that there is no maximum. This can only be set when the RTCDataChannel is created by calling RTCPeerConnection.createDataChannel(), using the maxRetransmits field in the specified options.

Value

The maximum number of times the browser will try to retransmit a message before giving up, or null if not set when RTCPeerConnection.createDataChannel() was called. The default is null.
