🔗 How to reuse business logic with Ash calculations and save time

As your codebase grows, you will realise that you spend less and less time implementing new features. Why? Because the majority of new features are extensions of existing ones. This is true for extending an existing table or introducing a new business logic. A new feature is a layer on the top of existing ones.

Today I am focusing on storing business logic in calculations.

This article assumes that you know Ash Framework, but if you are new to Ash framework, don’t worry. You can check out my serie “Ash framework for Phoenix developers”.

At this point, I am assuming that that you know what Ash resources and domains are, so I will introduce you to calculations right away!
