Takes an array of items and a Workbox Strategy and warms the strategy’s cache with those items at install. Useful for getting specific items into cache but allowing them to be updated outside of the Service Worker install cycle

Give users of page/image/resource recipes the ability to warm those caches using warmStrategyCache functionality. Also allows them to include plugins if desired (for instance, to normalize URLs coming into the cache)

While precache will still work, and that will be tried first, the files will be saved in a workbox-offline-fallbacks cache and the cache will try to be retrieved from there if precache fails.
