In the code example, caches is a property of the ServiceWorkerGlobalScope. The code also deletes all caches that aren't named in CURRENT_CACHES. It maps a shorthand identifier for a cache to a specific, versioned cache name. Though there's only one cache in this example, the same approach can be used for multiple caches. The code snippet also shows a best practice for versioning caches used by the service worker. It will return a normal response object that has the appropriate error code. Note that an HTTP error response (e.g., 404) will not trigger an exception. The code handles exceptions thrown from the fetch() operation. If there isn't a matching font, the code fetches the font from the network and uses Cache.put() to cache the fetched resource. The code then uses Cache.match() to see if there's already a matching font in the cache, and if so, returns it. (see selective caching live) The code uses CacheStorage.open() to open any Cache objects with a Content-Type header that starts with font/. This code snippet is from the service worker selective caching sample. Returns a Promise that resolves to an array of Cache keys. If no Cache entry is found, the promise resolves to false. lete(request, options)ДЇinds the Cache entry whose key is the request, returning a Promise that resolves to true if a matching Cache entry is found and deleted. Takes both a request and its response and adds it to the given cache. Takes an array of URLs, retrieves them, and adds the resulting response objects to the given cache. This is functionally equivalent to calling fetch(), then using put() to add the results to the cache. Takes a URL, retrieves it and adds the resulting response object to the given cache. Returns a Promise that resolves to an array of all matching responses in the Cache object. Returns a Promise that resolves to the response associated with the first matching request in the Cache object. See Deleting old caches for more information. Make sure to version caches by name and use the caches only from the version of the script that they can safely operate on. The browser will generally delete all of the data for an origin or none of the data for an origin. The browser does its best to manage disk space, but it may delete the Cache storage for an origin. Cache quota usage estimates are available via the StorageManager.estimate() method. Each browser has a hard limit on the amount of cache storage that a given origin can use.

You are also responsible for periodically purging cache entries. Use CacheStorage.open() to open a specific named Cache object and then call any of the Cache methods to maintain the Cache. Items in a Cache do not get updated unless explicitly requested they don't expire unless deleted. in a ServiceWorker) handles Cache updates. You are responsible for implementing how your script (e.g. You don't have to use it in conjunction with service workers, even though it is defined in the service worker spec.ДЄn origin can have multiple, named Cache objects. Note that the Cache interface is exposed to windowed scopes as well as workers. How long a Cache object lives is browser dependent, but a single origin's scripts can typically rely on the presence of a previously populated Cache object. The Cache interface provides a persistent storage mechanism for Request / Response object pairs that are cached in long lived memory.
