API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

• BREAKING: focus, hover, press, inView shorthand props — removed in v2.0.0-beta.1. Use whileFocus, whileHover, whilePress, and whileInView for animations, and full event handlers (e.g. @hoverStart, @pressStart) for logic source
• NEW: v-motion directive — new in v2.0.0-beta.1, enables declarative animations on any element without requiring a <motion> component wrapper source
• BREAKING: ESM-only — v2.0.0-beta.1 dropped CommonJS support. The package now only ships ESM (.mjs) exports source
• NEW: MotionPlugin — new in v2.0.0-beta.1, a Vue plugin for global v-motion and custom preset directive registration
• NEW: createPresetDirective() — new in v2.0.0-beta.1, allows creating reusable animation directives with baked-in motion options
• BREAKING: AnimatePresence lazy discovery — v2.0.0-beta.1 refactored to use data-ap attribute for lazy discovery instead of eager registration source
• DEPRECATED: staggerChildren and staggerDirection — deprecated in v1.4.0 in favor of using the stagger() utility within the transition prop source
• NEW: stagger() utility — correctly handles staggering for newly-entering siblings alongside existing ones since v1.7.0 source
• NEW: useTransform output maps — supports providing multiple output value maps for complex coordinate transformations since v1.9.0 source
• NEW: Reorder auto-scrolling — supports automatic parent container scrolling when a Reorder.Item is dragged to the edges since v1.8.0 source
• NEW: useScroll VueInstance support — container and target options now accept VueInstance (ref to component) since v1.6.0 source
• NEW: useInView root option — now accepts MaybeRef for dynamic root element assignment since v1.6.0 source
• NEW: AnimatePresence direct children — supports multiple direct motion components as children since v1.10.0 source
• NEW: delayInMs — exported as a standalone utility function for time-based animation delays since v1.6.0 source

Also changed: useTransform reactive update fix (v1.2.1) · sequence at relative start (v1.3.0) · AnimatePresence custom prop fix (v1.3.0) · motionGlobalConfig exported (v2.0.0-beta.1) · FeatureBundle tree-shaking architecture (v2.0.0-beta.1)

Best Practices

• Use LazyMotion + m component instead of motion to reduce the initial bundle from ~34kb to ~6kb — load domAnimation (+18kb) for variants/exit/gestures or domMax (+28kb) when you also need drag and layout animations. Add :strict="true" to catch accidental motion imports inside LazyMotion at dev time source
• Render live motion value output with <RowValue:value="motionValue" /> rather than syncing to Vue state — RowValue writes to innerHTML directly and bypasses Vue's reactivity cycle, keeping fast-changing values off the render path source
• Set reducedMotion="user" on MotionConfig at the app root — the default is "never", meaning transform and layout animations run regardless of the OS accessibility setting unless you explicitly opt in source
• For layout animations, apply changing CSS to :style (not :animate) and let the layout prop handle the transition — if the value is placed in :animate, Motion's FLIP measurement will conflict with it source
• Set borderRadius and boxShadow via :style (not CSS classes) on layout-animated elements — Motion auto-corrects scale distortion on these properties only when they are set as inline style motion values source
• Add layoutScroll to scrollable container ancestors and layoutRoot to fixed-position ancestors of layout-animated elements — without these props, Motion measures child positions incorrectly when scroll offset or viewport offset is non-zero source
• Never place v-if on AnimatePresence itself — if it unmounts, it cannot intercept the exit of its children. The conditional must be on the direct child:

<AnimatePresence v-if="isVisible"><Component /></AnimatePresence>

<AnimatePresence><Component v-if="isVisible" /></AnimatePresence>

source

• Use dynamic variants with the custom prop for per-element stagger rather than computing delay in reactive Vue state — pass :custom="index" to each motion component and resolve the delay inside the variant function, keeping stagger logic declarative and allocation-free source
• Prefer useMotionValue over CSS variable animation for values used across many children — animating a CSS variable always triggers paint on every frame, while a MotionValue passed to :style runs through Motion's optimised DOM renderer without touching the Vue render cycle source
• Use the v-motion directive (new in v2.0.0-beta.1) to add animation to any native HTML or SVG element without a wrapper <motion> component — register globally via app.use(MotionPlugin) or per-component via createMotionDirective. Register reusable animation presets via the presets option to create project-wide shorthand directives like v-fade-in source
