Working with the Cache API

The caches interface

The Cache API provides every web application with a caches interface, which gives us access to the cache storage of our application. Multiple sub-caches can be opened inside the cache storage. Let’s see how to open a cache in it using the caches interface.

The caches.open(name: string) method

The open(name) method will open the cache (with the given name) if it already exists. Otherwise, it will create one and then open it.
