jerrar670 Implement Lenis Smooth Scroll
This skill guides you through adding buttery smooth scrolling to a React/Next.js application using @studio-freight/lenis (or the newer lenis package).
Prerequisites
- A React or Next.js project.
Steps
1. Install Dependencies
Install the Lenis package.
npm install lenis
# OR depending on version preference
npm install @studio-freight/lenis
2. Create the Lenis Hook/Component
It's best to encapsulate Lenis in a reusable component or hook.
Option A: Global Component (Recommended for Next.js App Router)
Create src/lib/lenis.ts or src/components/SmoothScroll.tsx.
// src/components/SmoothScroll.tsx
'use client'
import { ReactNode, useEffect } from 'react'
import Lenis from 'lenis'
export default function SmoothScroll({ children }: { children: ReactNode }) {
useEffect(() => {
const lenis = new Lenis({
duration: 1.2,
easing: (t) => Math.min(1, 1.001 - Math.pow(2, -10 * t)),
orientation: 'vertical',
gestureOrientation: 'vertical',
smoothWheel: true,
})
function raf(time: number) {
lenis.raf(time)
requestAnimationFrame(raf)
}
requestAnimationFrame(raf)
return () => {
lenis.destroy()
}
}, [])
return <>{children}</>
}
3. Integrate into Layout
Wrap your main application or layout content with the component.
Next.js App Router (layout.tsx):
import SmoothScroll from '@/components/SmoothScroll'
export default function RootLayout({ children }) {
return (
<html lang="en">
<body>
<SmoothScroll>
{children}
</SmoothScroll>
</body>
</html>
)
}
Best Practices
- Performance: Ensure
requestAnimationFrameis optimized. - Scroll Restoration: Lenis usually handles this, but verify
scrollRestorationworks as expected in Next.js. - GSAP Integration: If using ScrollTrigger, ensure you update ScrollTrigger on Lenis scroll.
// Inside useEffect // lenis.on('scroll', ScrollTrigger.update) // gsap.ticker.add((time)=>{lenis.raf(time * 1000)}) // gsap.ticker.lagSmoothing(0)
