Do you really need TypeScript in Dataverse?
Do you bring a tank to a Nerf gun fight?
Most form scripts in PowerApps Model-Driven Apps are tiny: – Show/hide a field – Trigger a lookup filter – Or yell at users when they enter garbage
💡 These are not complex apps. They’re micro-patches for the UI.
And you’re not even allowed to touch the raw HTML. You can only work through the official SDK — no DOM party tricks here.
So… TypeScript? – You add a build pipeline – You compile before testing – You write type annotations for functions you barely use twice – You debug through source maps, not your actual code
All for a script that’s 50 lines and can’t even leave the form it was born in.
Modern JS already gives you: – let, const, arrow functions – ?. and ?? for clean null checks – async/await pattern – Template strings and object destructuring
Want type hints? Use a bit of JSDoc and enjoy 90% of the benefits.
Unless you: – Build shared libraries – Write form logic for 20+ entities – Or maintain a long-term complex project… – With a lot of team members
Then yes, TypeScript ‘could’ help.
But if you’re just poking a form to behave itself? Stick to JS: Keep It Stupid Simple!
