Examples

While 21st.dev hosts a wide array of React UI components, the platform also empowers developers to contribute their own creations. Publishing a component is a streamlined process, typically taking just a minute. Components undergo a review process, moving from on_review to posted and potentially to featured status, ensuring high-quality contributions adhere to visual design, code structure, theming, and accessibility standards. The recommended file structure for components is as follows:

your-component/
??? code.tsx
??? tailwind.config.js
??? globals.css
??? demos/
    ??? default/
    ?   ??? code.demo.tsx
    ?   ??? preview.png
    ?   ??? video.mp4
    ??? advanced/
        ??? code.demo.tsx
        ??? preview.png
        ??? video.mp4
