# Dashboard SDK

> The Vite plugin that powers admin and vendor panel extension — file-based routing, virtual modules, and block resolution.

<Note>
  This reference is being written. The outline below is the intended structure.
</Note>

<Info>
  **Not Medusa's admin-vite-plugin.** The dashboard SDK is Mercur's own extension framework for both panels — it scans `src/routes/**/page.tsx` files, generates navigation, and injects everything through `virtual:mercur/*` modules at build time. Medusa's `defineWidgetConfig` / `defineRouteConfig` and widget zones are not part of this model. Start with [Extending Panels](/rc/resources/customization/extending-panels) for the authoring guide; this page covers the plugin's internals and options.
