If you emptied the inventory cache and try to access anything in your inventory, nothing will happen because your viewer doesn't have cached assets. In the meantime, if you emptied the image cache, your graphics card has no local copies of cached images to draw on, and everything will appear gray. The inventory cache can take a while, if you have a lot of items. Thanks to Mat Scales who wrote the original version of this article, which first appeared on WebFundamentals.And it will simply repopulate. This function returns a Promise that resolves to true if the cache existed and was deleted, or false otherwise. put ( '/test.json', new Response ( ' ) Deleting a cache # Create a new entry for test.json and store the newly created response.Ĭache. Retrieve data.json from the server and store the response. The second must be a Response, either from the network, or generated by your code. The first can either be a Request object or a URL ( string). cache.put #įinally, there is cache.put(), which allows you to store either a response from the network, or create and store your own Response. This uses the same matching rules described in the section on retrieving. In each of these cases, a new entry overwrites any matching existing entry. This works similarly to calling cache.add for each individual request, except that the Promise rejects if any single request is not cached.

It works similarly to add(), but takes an array of Request objects or URLs ( strings). Retreive data.json from the server and store the response.Ĭache. Such requests can only be stored with put. Note that cross-origin requests not in CORS mode cannot be stored because they return a status of 0.

If the fetch fails, or if the status code of the response is not in the 200 range, then nothing is stored and the Promise rejects. It makes a request to the network and stores the response in the cache. It takes one parameter, either a Request or a URL ( string). There are three ways to add an item to a cache - add, addAll, and put. This method returns a Promise that resolves with the Cache object. If the named cache does not exist, it is created. To open a cache, use the caches.open(name) method, passing the name of the cache as the single parameter.

Browser implementations vary, but the amount of storage available is usually based on the amount of storage available on the device. In short, a lot, at least a couple of hundred megabytes, and potentially hundreds of gigabytes or more.

However, the requests and responses can contain any kind of data that can be transferred over HTTP. The caches only store pairs of Request and Response objects, representing HTTP requests and responses, respectively. The Cache API can be accessed from a window, iframe, worker, or service worker. It is exposed via the global caches property, so you can test for the presence of the API with a simple feature detection: const cacheAvailable = 'caches' in self The Cache API is available in all modern browsers. However, the API can also be used as a general storage mechanism. The Cache API was created to enable service workers to cache network requests so that they can provide fast responses, regardless of network speed or availablity. These might be regular requests and responses created in the course of running your application, or they could be created solely for the purpose of storing data for later use. The Cache API is a system for storing and retrieving network requests and their corresponding responses.
