Quick start

A usage example from the http-cache-semantics README.

jsFull README ↗
const policy = new CachePolicy(request, response, options);

if (!policy.storable()) {
    // throw the response away, it's not usable at all
    return;
}

// Cache the data AND the policy object in your cache
// (this is pseudocode, roll your own cache (lru-cache package works))
letsPretendThisIsSomeCache.set(
    request.url,
    { policy, body: response.body }, // you only need to store the response body. CachePolicy holds the headers.
    policy.timeToLive()
);
