Deploy

Deploying ships your Rayfin project to a Fabric app — a managed, Microsoft Fabric-hosted instance of your backend and frontend. Fabric provisions the database, authentication, static hosting, and API endpoints; one CLI command builds and ships all of it.

npx rayfin login
npx rayfin up

rayfin up builds your static content, deploys it, pushes your rayfin.yml settings to the remote service, and applies any pending database schema changes — all in one step. Run it again for every change you want to ship, including schema-only changes.

Confirm the deployment is healthy:

npx rayfin up status
