How to Utilize
NNUI-KIT components live directly in the document Light DOM. You can use them via declarative HTML, with our first-class React wrapper, or platform-natively in Svelte, Vue, Astro, and HTMX:
React 18 & 19 (Next.js 15 App Router)
import 'nnui-kit/css';
import 'nnui-kit/client';
import { CheckboxRadio } from 'nnui-kit/react';
Universal Web Components (Vue 3, Svelte 5, Astro, HTMX)
<!-- Automatically registers <ui-checkbox> and <nnui-checkbox> -->
import 'nnui-kit/css';
import 'nnui-kit/client';
Platform Features
Zero Shadow DOM
Element lives in the Light DOM. Tailwind and global CSS apply directly.
persist="url | local"
Add declarative persistence attribute to auto-sync state with URL search params.
sync="cross-tab"
Synchronize changes across all open browser tabs via BroadcastChannel.
