BackgroundFetchRegistration.matchAll()

The matchAll() method of the BackgroundFetchRegistration interface returns an array of matching BackgroundFetchRecord objects.

Syntax

matchAll(request)
matchAll(request,options)

Parameters

request

The Request for which you are attempting to find records. This can be a Request object or a URL.

options Optional

An object that sets options for the match operation. The available options are:

ignoreSearch

A boolean value that specifies whether to ignore the query string in the URL. For example, if set to true the ?value=bar part of http://foo.com/?value=bar would be ignored when performing a match. It defaults to false.

ignoreMethod

A boolean value. When true, prevents matching operations from validating the Request http method. If false (the default) only GET and HEAD are allowed.

ignoreVary

A boolean value. When true indicates that the VARY header should be ignored. It defaults to false.

Return value

A Promise that resolves with an array of all matching BackgroundFetchRecord objects.

Exceptions

InvalidStateError DOMException

Returned if the recordsAvailable flag is false, indicating that there is no fetch in progress.

Examples

Use matchAll() with no parameters to return all of the records in a background fetch.

const records = await bgFetch.matchAll();
console.log(records); // an array of BackgroundFetchRecord objects
