morphicons

morphicons is a 6.5 KB library that morphs any stroke SVG icon into any other with interruptible spring physics, working across Lucide, Tabler, Heroicons, Iconoir and other sets that share a 24px grid. It solves the alignment between two shapes in closed form, so congruent pairs rotate and others morph, with no rotation groups to declare by hand and sharp corners at rest. It has no dependencies and drives React, Vue, Svelte, React Native, Astro or plain JavaScript.
