Looking at this, it has similar aspects as ASP.NET Core, and the same flaws as the Controller per class design used. Methods such as "index", "show" and "store" do not share a state, they shouldn't share a class either.

However, you can rectify this, by just not trying to share a class with any of those. In .NET Steve Smith, aka Ardalis shows how to do this with his Clean architecture [1]. One idea is to make a class for each endpoint. This also makes it easier for "Update" classes to share functionality with other "Update" classes and so on.
