2024 Power Apps Coding Standards For Canvas Apps

Welcome to the Power Apps Coding Standards For Canvas Apps.

In this guide you will find 50+ pages of coding rules , guidelines and best practices I use everyday to create Power Apps Canvas apps. I have spent the last 3 years building Power Apps every day. Now I want to share the knowledge I’ve gained in this set of easy-to-understand, actionable examples.

Power Apps already has an official set of canvas coding standards released back in 2018. So why did I make my own? A few reasons:

I wanted an updated set of standards and guidelines for 2024 that includes all of the latest features

These coding standards can be continuously improved as new Power Apps features hit “general availability” in 2025, 2026, 2027 and beyond

Readers can leave comments on my website describing their own best practices which I can incorporate into future versions
