an underlying cache library of your choice. That way you can fully harness the power of Scala while caching your data. It works great both if you need to cache something manually and if all you need is method call memoization. My personal case was a tad more complicated, though. What I needed to do was to cache authentication tokens with a time to live (TTL) corresponding to the token’s expiration time. Unfortunately, scalacache API forces you to define the TTL upfront. Fear not, for this is a highly extensible library. It let me define a generic method to do just that, and yet still allowed for flexibility provided by its       case Some(found) => M.pure(found)       case None =>         M.flatMap(value) {           case (v, ttl) => with Keycloak as a Single Sign-on server. That is really important, but almost no real application can work without a back-end. That’s why today we’ll delve into the problem of authorizing requests in the server application. If we’re using an application container this job will probably be much easier. Keycloak provides some out of the box adapters for most mainstream servers bit of configuration. That’s a piece of cake. That’s why we’ll look into something different: adding OAuth2 and in particular Basically every application needs some kind of authorization mechanism. That’s obvious. If we have some container at our disposal which serves HTML for every requested website, we can probably just enrich it with some library, change some XMLs and we’re basically done. Unfortunately that’s not the case with single page applications. Yes, we can still have a container, that will handle things on the backend (which we won’t in this tutorial, but let’s not jump to it yet), but there’s no such magic wand for the frontend. There are some libraries, that will help you in some particular cases, but when I was looking at the authorization needed for my current project, none of them were good enough, and I didn’t want to configure some big library just to do something that can be
