drei — Helper Components for React Three Fiber
drei is the official R3F helpers library — pre-built components for camera controls, environments, scroll, post-processing, and more.
@react-three/drei is the helpers library that turns R3F from "Three.js in React" into "rapid 3D web development". 200+ pre-built components: OrbitControls (camera), Environment (HDRI lighting), ScrollControls (scroll-driven scenes), Float (floating motion), useGLTF (model loading), Text and Text3D, Sky, Stars, useTexture. Without drei, you'd write 50% more code on every R3F project. With drei, the React mental model dominates — composable components, prop-driven config, no imperative setup. I use drei on every R3F project; it's essentially required tooling. The package is large but tree-shakes cleanly — only the components you import end up in the bundle.
When this is overkill
If the goal is a simple e-commerce listing or content blog, a full r3f drei helpers setup is overkill — a CSS-driven hero plus static images converts just as well at 1/10 the cost. r3f drei helpers earns its keep when the brand needs a memorable visual moment or when 3D actually clarifies the product (configurators, tours, demos).
What you get hands-off
After delivery: source repository on GitHub (private), commented code, a 5-min Loom walkthrough explaining the scene logic, and the asset pipeline documented. First year of hosting and minor revisions is included. After that we agree on a maintenance plan if needed.
What this delivers
Concrete output: a working r3f drei helpers integration on a real production site, not a demo. The integration includes device-tier detection so weak phones get a lighter version automatically. Source files are handed over in their original formats — Blender, GLSL, glTF — so any future developer can continue where I stopped.
How I work with it
On a typical project, r3f drei helpers ships as a self-contained module: one entry-point JS file, one CSS file, asset bundle below 1.5MB total. I keep the integration sandboxed so the rest of the site stays SEO-friendly classical HTML. Frame budget targets 60 FPS on a mid-range Android, with a measurable fallback below.
