Feature: #98921 - Get multiple items by common key prefix from local storages

See forge#98921

Description

A new method getByPrefix() is added to the module @typo3/backend/storage/abstract-client-storage, affecting its implementations

  • @typo3/backend/storage/browser-session
  • @typo3/backend/storage/client

Impact

A developer is now able to obtain multiple items prefixed by a given key either from localStorage or sessionStorage.

Example:

import Client from '@typo3/backend/storage/client';

Client.set('common-prefix-a', 'a');
Client.set('common-prefix-b', 'b');
Client.set('common-prefix-c', 'c');

const entries = Client.getByPrefix('common-prefix-');
// {'common-prefix-a': 'a', 'common-prefix-b': 'b', 'common-prefix-c': 'c'}
