Developers are re‑evaluating the practice of placing Power Apps logic directly in component properties. While inline formulas are easy to read, they hinder code review, reuse, and scalability. The article explains that User Defined Functions (UDF) and Behaviour UDFs, now available as app‑formula properties, allow reusable blocks of Power FX code.

Inline should be limited to single‑action, non‑reusable snippets; otherwise code belongs in a UDF or Behaviour UDF, improving maintainability and enabling version control. Server‑side options such as Dataverse functions and Power Automate flows provide cross‑app reusability but require premium licenses, have runtime limits, and can introduce latency. The guidance targets Power Apps creators, solution architects, and IT teams managing low‑code portfolios, urging a shift toward modular code blocks to align with professional development standards.

Adoption of this approach can reduce debugging time, enhance collaboration, and prepare apps for future integration with pro‑code solutions. The author, David Wyatt, also offers a web tool for extracting app code, illustrating practical support for the recommended transition.
