RTCDataChannel: maxPacketLifeTime 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
maxPacketLifeTime returns the amount of time, in
milliseconds, the browser is allowed to take to attempt to transmit a message, as set
when the data channel was created, or null. This limits how long
the browser can continue to attempt to transmit and retransmit the message before giving
up.
Value
The number of milliseconds over which the browser may continue to attempt to transmit
the message until it either succeeds or gives up. If not set when
RTCPeerConnection.createDataChannel() was called to create the data
channel, this value is null.
