CLI

Install a registry item with the command shown on its docs page.

npx shadcn@latest add https://mwui.vercel.app/r/autosize-textarea.json

The command that's displayed uses the homepage value from registry/config.ts for the base URL.

Human-facing item pages also work with the shadcn CLI through content negotiation. For example, a browser can view /components/autosize-textarea, while the CLI receives the installable item JSON from the same URL:

npx shadcn@latest add https://mwui.vercel.app/components/autosize-textarea

Use the package manager selector on item pages to switch between npm, pnpm, yarn, bun, vite+, and deno commands.

Endpoints

The registry index is served from both the root and the /r path, while installable item JSON lives under /r:

Authored metadata is validated against the schemas from shadcn/schema, so anything these routes serve is CLI-compatible.
