If the project has components.json (shadcn/ui installed), use the shadcn theme:
import { shadcn } from '@clerk/themes'
<ClerkProvider
appearance={{
theme: shadcn,
}}
/>
Also import shadcn CSS in your global.css:
@import 'tailwindcss';
@import '@clerk/themes/shadcn.css';
| Issue | Solution |
|---|---|
| Colors not applying | Use colorPrimary not primaryColor |
| Logo not showing | Put logoImageUrl inside layout: {} |
| Social buttons wrong | Add socialButtonsVariant: 'iconButton' in layout |
| Styling not working | Use appearance prop, not direct CSS (unless with bring-your-own-css) |
