Custom Primitives – Refactoring – Speed – PwP Episode 23

Custom primitives, an example of how refactoring accelerates team speed, part of the Clear Measure Way

In this episode, Jeffrey discusses custom primitives, a specific refactoring. Refactoring is one of the engineering practices that increases team speed. Moving fast is part of the Clear Measure Way.

With a refactoring mindset, we modify existing code so that a new change appears as if we had designed it that way since the genesis of the software. We don’t allow something to appear “bolted on”:

• An Onion Architecture mindset encourages us to push dependencies to the edges and pull core concepts to the center
• Common operations on primitives clutter the UI, one of the edge interfaces in any application
• Pulling common operations into the core model of an application limits repetition and reduces concept count
• Options for refactoring custom usages of primitives
• C# implicit operators allow the rest of the application to believe our decimal is a normal C# decimal
• A custom primitive allows the execution of custom logic everywhere while keeping the logic in one place.
