The responseReady read-only property of the BackgroundFetchRecord interface returns a Promise that resolves with a Response.

A Promise that resolves with a Response.

In this example an individual BackgroundFetchRecord is returned using BackgroundFetchManager.fetch(). The value of responseReady is returned and logged to the console.

bgFetch.match("/ep-5.mp3").then(async (record) => {
  if (!record) {
    console.log("No record found");
    return;
  }

  const response = await record.responseReady;
  console.log(`Here's the response`, response);
});
