FR-AI / ANALYSISWhy it is worth attention
It eliminates hand-declared rotation groups and per-pair keyframes by solving optimal similarity in closed form, while keeping the core DOM-free, offering React, DOM, and pure-core APIs with strong performance and small bundle sizes.
Who it is for
- React developers building animated icon systems or UI components
- Frontend engineers using Lucide, Tabler, Heroicons, or Iconoir
- Design-system maintainers wanting drop-in animated icons
- Motion/UI developers needing gesture- or scroll-driven icon transitions
Use cases
- Animated hamburger-to-close menu buttons
- Spring-physics icon transitions in navigation and toolbars
- Gesture- or scroll-scrubbed icon morphs via controlled progress
- Cross-library icon morphs on a shared 24×24 grid
Strengths
- No hand-declared rotation groups; Procrustes alignment detects rotation automatically
- Zero runtime dependencies with no per-frame numeric allocation and small gzip footprint
- Drop-in React replacement for lucide-react with SSR and reduced-motion support
- Core is DOM-free, enabling React, vanilla DOM, and future React Native adapters from one package
Considerations
- Only stroke-drawn icons morph correctly; filled or outline-filled glyphs parse but look wrong in transit
- Icon data must be literal path/node lists without transforms, and endpoints must share a coordinate space or use fitIcon
- ESM-only, with React as an optional peer dependency requiring React >=18

Usage
Description
Any icon morphs into any other — universal morphing for stroke-based icons with spring physics. Zero dependencies, ~6 KB gzip.
