-> High level API is deprecated. Please write on your own `@vitejs/plugin-rsc/{rsc,ssr,browser}` integration.

-This is a wrapper of `react-server-dom` API and helper API to setup a minimal RSC app without writing own framework code like [`./examples/starter/src/framework`](./examples/starter/src/framework/). See [`./examples/basic`](./examples/basic/) for how this API is used.

 ## CSS Support
 
 The plugin automatically handles CSS code-splitting and injection for server components. This eliminates the need to manually call [`import.meta.viteRsc.loadCss()`](#importmetaviterscloadcss) in most cases.
