All of us are eager to start writing real-world applications using ZIO (Scala library). But ZIO is still quite new, and its ecosystem is still incomplete. So while we wait for ZIO-HTTP and ZIO-JDBC (or whatever else comes in the future) to happen, we will have to end up integrating ZIO with other frameworks that can communicate with the outside world. In this article, I want to explore what this kind of integration might look like for two of the most popular libraries – Slick and Akka HTTP.
