Mastering Functional Programming

Example specification

The example in question will be an online store. So, we will have the entities for the customers, the goods, and we will have an ability to describe orders that the customers make.

We will store all of these entities in a database, and we will expose the functionality to create new users and new orders, and to list existing orders and goods via an HTTP interface.

Next, let's take a look at how this architecture can be put into practice. We will be discussing the architecture as a whole, and we will be introducing various functional programming libraries in the process. This will facilitate an integrated view of how server-side programming can be done with Cats.

Please keep in mind that we will not be going in-depth into ...
