BackgroundFetchRecord

Limited availabilityAvailable in 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().

Instance properties

• request Read only Experimental
  • : Returns a Request.
• responseReady Read only Experimental
  • : Returns a promise that resolves with a Response.

Examples

In this example an individual BackgroundFetchRecord is returned using BackgroundFetchRegistration.matchAll(). The request and 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);
});
