Lenis Smooth Scroll Tutorial — Setup and Integration
A practical Lenis tutorial covering installation, ScrollTrigger integration, mobile considerations, and accessibility.
Lenis (from Studio Freight) is the smooth-scroll library that replaced locomotive-scroll for premium 3D sites. Setup: npm install lenis, import, instantiate, raf-driven update loop, integrate with ScrollTrigger via the proxy pattern. Mobile considerations: Lenis works on touch but feels different from native iOS scroll — some clients want it disabled on mobile via media query. Accessibility: respect prefers-reduced-motion to disable smoothing for users who need it. The library is under 8KB minified — minimal cost for major polish improvement.
Common pitfalls
Three failure modes I see beginners hit: (1) trying to render before assets finish loading — always wait for the loader callback, (2) using full-resolution textures on mobile — always have KTX2 or compressed alternatives, (3) leaving the scene rendering when off-screen — pause the render loop with IntersectionObserver. Each pitfall has a clear fix; the trick is recognizing the symptom.
Want a faster path
If your timeline is short and the project matters commercially, hiring an experienced developer often beats self-learning by 4-6 weeks of effort. I take on Lenis Smooth Scroll Tutorial — Setup and Integration projects on a fixed-price basis — you get the working result without the learning detour. Reach out via the contact page if a structured engagement makes sense for what you're building.
Further reading
Three resources I recommend after this guide: the official Three.js fundamentals docs (excellent and underused), Bruno Simon's Three.js Journey (paid, comprehensive), and the React Three Fiber docs if you'll work in React. Beyond that, reading other developers' source on GitHub — search for 'three-js portfolio' on GitHub trending — accelerates learning faster than any tutorial.
Prerequisites
Before starting on lenis smooth scroll tutorial, you need: a JavaScript baseline (familiarity with ES modules, async/await, npm), a working local dev environment (Node 18+, a code editor), and a basic mental model of what WebGL renders. You don't need 3D modeling skills — for most tutorials, the assets are provided. Time investment: 2-4 hours of focused work for the basic version.
