We talk about guides and rules for programmers in the scope of their code style and object style. With the help of book author Matthias Noback we realize that there is more possible with static analysis than one might think. And there is definitely a use for a catalogue of stereotypes of classes.

In this episode, we discussed with Nik Graf about GraphQL and why he thinks it is a future-proof way to create APIs for client applications. We tried to distill the main advantages over classical REST, and figured out scenarios when it shines, but also took a look at possible drawbacks. TL/DR: Everything you need to know if you are interested to get started with GraphQL.
