React Three SPA
React + R3F for 3D web SPAs.
Stack Components
Why
Declarative Three.js, React reconciler for 3D. JavaScript is used by 62% of developers per the Stack Overflow 2024 survey, and React holds 40% framework market share (State of JS 2024).
Vite replaced Webpack as the default bundler, cutting dev server startup from 30s to <1s.
When
Use for 3D visualizations. Avoid for 2D-only apps.
How
Example
Common Problems
- ⚠Performance — use instancedMesh for repeated geometry
- ⚠Memory — dispose geometries and materials
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Use @react-three/drei for helpers
- ✓Memoize geometry creation
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit
FAQ
What is React Three SPA and what projects is it for?
React + R3F for 3D web SPAs. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.
How do I spin up a working demo with React Three SPA in 10 minutes?
Two steps: (1) npm i three @react-three/fiber; (2) Use Canvas component. Get the local dev server running, then wire one real data source to verify the end-to-end loop.
What is the most common pitfall with React Three SPA and how do I avoid it?
The most common pitfall is: Performance — use instancedMesh for repeated geometry. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.
What are the best practices for React Three SPA?
Best practices for React Three SPA include: Use @react-three/drei for helpers; Memoize geometry creation; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use @react-three/drei for helpers" — should be set up at project init to avoid costly rework later.
When should I NOT choose React Three SPA?
Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). React Three SPA shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
