Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The congestionControl read-only property of the WebTransport interface indicates the application's preference for either high throughput or low-latency when sending data.
The value is set in the WebTransport() constructor options.
Value
A string with one of the following values:
default-
The default congestion control tuning for the transport. This is the default.
throughput-
The application prefers congestion control to be tuned for throughput.
low-latency-
The application prefers congestion control to be tuned for low-latency.
Examples
This example shows how to get the congestionControl preference.
As this is not explicitly set in the constructor, the result is default.
const url = "https://example.com:4999/wt";
const transport = new WebTransport(url);
console.log(transport.congestionControl); // default
