0.2.0-next.3

Patch Changes

• 7e0fcae: Fix AnimatePresence mode="wait" laying the incoming child out while the outgoing one is still exiting.

  The incoming child was kept out of flow by a display: none CSS transition delayed by context.remaining(), which reads a duration published by the outgoing child's outro. Svelte builds the incoming keyed block before tearing the outgoing one down, so the intro almost always read 0, emitted no CSS at all, and both children shared the layout for the whole exit.

  The incoming child is now taken out of flow imperatively at intro time and restored once waitForExit() resolves, which removes the ordering dependency entirely. A finished exit also drops its node out of flow immediately, rather than lingering until Svelte's own outro timer elapses, which previously left a short window where both children were laid out.

  This applies to SVGElement children as well as HTMLElement ones. Children that are already out of flow (position: absolute / fixed) are left alone, since they cannot share layout with a sibling and hiding them would zero out the box read by projection and onLayoutMeasure.

  mode="sync" and mode="popLayout" are unaffected.

0.2.0-next.2

Patch Changes

• e83c2c7: Fix variant staggering and self-resizing layout animations.

  Sibling motion components shared a context scope

  motion components are hand-written component functions rather than compiled .svelte modules, so Svelte never opened a component context for them and setContext wrote into the nearest compiled ancestor's context map — which every sibling motion component shares. Contexts leaked sideways in mount order, so a variant parent adopted only its first child and each later child parented to its previous sibling, forming a chain instead of a fan-out.

  The visible symptom was that staggerChildren and staggerDirection did nothing: with one variant child per level there was nothing to stagger across, and every child received the same delayChildren. Anything relying on parent/child motion relationships between siblings was affected.

  Plain layout animations snapped instead of animating

  Framer-motion takes a pre-commit measurement on every render, so any prop that changes layout is covered. A Svelte effect only re-runs for the sources it reads, and the pre-pass tracked layoutDependency alone — so an element that resized itself (for example via style) never snapshotted and jumped straight to its new size.

  layoutDependency also absorbed the ambient AnimatePresence and Reorder version counters. Any element under a presence boundary therefore saw a constant dependency and suppressed its own snapshots entirely. Those counters are now tracked separately and add snapshot opportunities rather than replacing the user's own layoutDependency, restoring framer-motion's semantics.

  layoutId shared-layout animations, exit animations, and Reorder are unaffected.

0.2.0-next.1

Patch Changes

• ed7a87c: Target ES2022 in tsconfig.json so packaged output keeps native class fields instead of downlevelled Object.defineProperty assignments, which broke subclass field initialisation in consumers.

0.2.0-next.0

Minor Changes

• 5013e2b: Rewrite the library against framer-motion@11.11.11 (previously 4.0.3) on Svelte 5 runes.

  New

  • Reorder.Group / Reorder.Item for drag-to-reorder lists.
  • LayoutGroup and the full projection engine, replacing AnimateSharedLayout.
  • AnimatePresence mode (sync | wait | popLayout) and usePresenceData.
  • WAAPI-accelerated animations, animate() sequences, and stagger().
  • Scroll (useScroll), viewport (whileInView), and useInView support.
  • Motion value hooks: useTime, useVelocity, useWillChange, useAnimate, useAnimateMini.
  • Subpath entries: motion-start/dom, /mini, /m, /client, /projection.

  Changed

  • Components and hooks are Svelte 5 runes-based; renderless Use*.svelte wrappers are gone in favour of plain functions and classes.
  • motion / m are proxies, so any element is available as motion.<tag>.
  • Gestures rewritten onto the shared Feature pipeline (hover, press, pan, drag, focus).

  Removed

  • AnimateSharedLayout — use LayoutGroup with layoutId.
  • MotionDiv — use motion.div.

0.1.21

Patch Changes

• 39bf8bf: Fix AnimatePresence presenceAffectsLayout no-op, isPresent race condition with framesync batcher, and double safeToRemove guard

0.1.20

Patch Changes

• 84d3657: fix: resolve bare dot and extension-less imports in value/ for Svelte REPL

  The Svelte playground CDN resolves ESM imports without a bundler, requiring explicit file extensions and no bare directory imports. Bare dot imports like from '.' compiled to JS caused the REPL to fail resolving dist/value/ as a directory path.

  Fixed by replacing all from '.', from '..', and extension-less relative imports within the value/ directory with explicit ./index.js paths and proper .js extensions.

0.1.19

Patch Changes

• e036a76: Remove sideEffects: false from package.json to fix module resolution in the Svelte REPL playground.

  Bundlers honour this flag by tree-shaking modules that are imported only for their side effects. In the Svelte playground this caused the module that resolves the "." bare specifier to be dropped entirely, producing:

  error occurred while trying to resolve . within npm://$/motion-start@0.1.18/dist/value/use-motion-template.js
