@yusukebe Hy, could you check this out please? :) Still very basic, no tests even yet, just to get feeling/idea if there would be interest to continue with this

At first glance, I don't think this is needed. We already have the built-in Cache Middleware. If you want to cache just "Response", it's enough to use it.

As per my understanding, that middleware only works on cloudflare an deno, and uses specific cache mechanism. This allows little bit more freedom, for example, by using redis which has TTL (unlike Cache API).

Also, correct me if I'm wrong, but that Cache API helps cache'ing it on Cloudflare/DenoDeploy level, basically "edge/cdn" rather than on server, right?

Forgot to mention - this allows to customize cache’ing keys. So for example, if you’re running A/B test, and store A/B tests list in cookie - you can use that cookie to allow to cache page rendered under specific A/B conditions.

Quite niche example, but solution is quite lightweight with provided flexibility.

@muningis

Thank you for the explanation! Makes sense.

Yes. The Cache API is standardized, but you can only use it in particular runtimes like Cloudflare Workers and Deno.

This middleware looks good. Let's go ahead.
