Developers define data models using TypeScript entities with decorators, and Rayfin automatically materializes them as SQL databases within Fabric, exposing data via GraphQL. Apps are hosted inside Fabric, inheriting its governance, compliance, security, and SSO authentication automatically. The workflow involves scaffolding a project with a single CLI command, using AI (e.g., GitHub Copilot) to customize the app, then publishing with one more command. It supports connecting to existing OneLake data or creating new durable data stores, making it accessible to non-developers who want to vibe-code dashboards and data apps without compromising enterprise compliance requirements. ## Full article daily.dev links to this article rather than hosting it.
