workbox-strategies.
An implementation of a cache-only request strategy.
This class is useful if you want to take advantage of any Workbox plugins.
If there is no cache match, this will throw a WorkboxError exception.

Methods
handle
handle(options)
Perform a request strategy and returns a Promise that will resolve with
a Response, invoking all relevant plugin callbacks.
When a strategy instance is registered with a Workbox route, this method is automatically called when the route matches.
Alternatively, this method can be used in a standalone FetchEvent
listener by passing it to event.respondWith().

handleAll
handleAll(options) returns Array of Promise
Similar to handle(), but
instead of just returning a Promise that resolves to a Response it
it will return an tuple of [response, done] promises, where the former
(response) is equivalent to what handle() returns, and the latter is a
Promise that will resolve once any promises that were added to
event.waitUntil() as part of performing the strategy have completed.
You can await the done promise to ensure any extra work performed by
the strategy (usually caching responses) completes successfully.
