Build Your First Microsoft Fabric App with Claude Code (Rayfin) — Part 1

In this end-to-end tutorial, I build and deploy a full-stack app inside Microsoft Fabric — no separate backend, no manual infrastructure.

Using the Rayfin framework and Claude Code, we go from an empty folder to a live, authenticated app with a real database in one sitting.

If you've been wondering what "Fabric Apps" actually are and how to build one, this is your zero-to-deployed starting point. 👇

🧩 What you'll learn in Part 1: ✅ Scaffold a Fabric App with a single command (npm create @microsoft/rayfin) ✅ How the Rayfin framework works — Auth, Data, and Static Hosting ✅ Run the app locally with hot reload ✅ Add a real feature end-to-end — task priorities (High / Medium / Low) across the data model, service, and UI ✅ Deploy the whole thing to Fabric with rayfin up — live URL + Microsoft sign-in
