Request.priority
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The priority read-only property of the Request
interface contains the hinted priority of the request relative to other
requests.
Value
A string indicating the hinted priority of the request. Possible values are:
high-
The request is at a high priority relative to the other requests of a similar type.
low-
The request is at a low priority relative to other requests of a similar type.
auto-
Default mode, which indicates no preference for the fetch priority. The browser decides what is best for the user.
Examples
In the following snippet, we create a new request using the
Request() constructor (for an API endpoint)
at a low priority, then save the priority of the request in a variable:
const myRequest = new Request('/background-api-call', { priority: 'low' });
const myPriority = myRequest.priority; // "low"
