anime.js (v4)

anime.js is a fast, lightweight JavaScript animation library with a small, composable API. v4 is a ground-up rewrite: it is modular and ESM-first — you import named functions (animate, createTimeline, …) rather than calling a single default anime() object as in v3. Always write v4-style code unless the user explicitly pins v3.

When to use this skill

• "Animate this element / these cards / this SVG."
• "Make a timeline that sequences several animations."
• "Add a staggered entrance / scroll-reveal / hover effect."
• "Morph this SVG path into that one" or "draw this SVG line on scroll."
• "Make this element draggable with momentum / springy motion."
• "Animate text in character by character."
• Any request to add motion to a web page, or to debug/upgrade existing anime.js.
