@reelkit/react

React components and hooks for building TikTok/Instagram Reels-style sliders. Virtualized rendering, touch gestures, keyboard/wheel navigation — all in ~2.6 kB gzip.

Installation

npm install @reelkit/react

Quick Start

import { useState } from 'react';
import { Reel, ReelIndicator } from '@reelkit/react';

function App() {
  const [index, setIndex] = useState(0);

  return (
    <Reel
      count={100}
      direction="vertical"
      afterChange={setIndex}
      itemBuilder={(i) => (
        <div style={{ width: '100%', height: '100%' }}>Slide {i + 1}</div>
      )}
    >
      <ReelIndicator count={100} active={index} />
    </Reel>
  );
}

Features

<Reel> — virtualized slider component (only 3 slides in DOM)
<ReelIndicator> — Instagram-style position dots
Auto-size — measures container via ResizeObserver, no explicit size props needed
Touch gestures — swipe with momentum and snap
Keyboard & wheel — arrow keys and scroll navigation
Loop mode — infinite circular scrolling
SSR ready — works with Next.js, Remix, and any SSR setup
TypeScript — full type safety
