BackgroundFetchRecord
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Note: This feature is available in Web Workers.
The BackgroundFetchRecord interface of the Background Fetch API represents an individual request and response.
A BackgroundFetchRecord is created by the BackgroundFetchRegistration.matchAll() method, therefore there is no constructor for this interface.
There will be one BackgroundFetchRecord for each resource requested by fetch().

Examples
In this example an individual BackgroundFetchRecord is returned using BackgroundFetchRegistration.matchAll(). The BackgroundFetchRecord.request and BackgroundFetchRecord.responseReady are returned and logged to the console.
bgFetch.match("/ep-5.mp3").then(async (record) => {
if (!record) {
console.log("No record found");
return;
}
console.log(`Here's the request`, record.request);
const response = await record.responseReady;
console.log(`And here's the response`, response);
});
