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 { OTPPINInput } from 'nnui-kit/react';

Universal Web Components (Vue 3, Svelte 5, Astro, HTMX)

<!-- Automatically registers <ui-otp-input> and <nnui-otp-input> -->
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.
