How to Build 60fps Canvas Particle Animations in Next.js 15 App Router

A tutorial published on DEV Community demonstrates how to implement smooth, 60fps particle drift animations in Next.js 15 using an isolated HTML5 2D canvas element. The approach avoids common performance pitfalls like layout recalculations and memory leaks that arise from heavy DOM manipulation or unrestricted CSS keyframes. The implementation uses React's useEffect and useRef hooks inside a client-only component, since browser APIs such as requestAnimationFrame are unavailable on the server. Key best practices highlighted include disabling server-side rendering via next/dynamic, explicitly cancelling animation frames on component unmount, and respecting the prefers-reduced-motion accessibility setting. A live demo of the technique has been deployed on Vercel as part of a café-themed web project.
