This section documents version-specific API changes — prioritize recent major/minor releases.
-
BREAKING: computedAsync — default flush changed from pre to sync in v14.0.0; code relying on deferred evaluation now runs synchronously by default source
-
BREAKING: useThrottleFn — aligned with traditional throttle behavior in v14.0.0 (trailing call behavior changed); previously called on both leading and trailing by default, verify options match expected behavior source
-
BREAKING: createSharedComposable — on client side, now returns only the shared composable (single value) instead of a tuple/object in v14.0.0 source
-
BREAKING: useAsyncState — in v13.7.0, globalThis.reportError is now the default onError handler; previously errors were silently swallowed if no handler was provided source
-
BREAKING: CJS build dropped in v13.0.0 — @vueuse/core is now ESM-only; require('@vueuse/core') no longer works source
-
BREAKING: Vue 3.5 is now required as a minimum peer dependency since v14.0.0 source
-
DEPRECATED: watchPausable — will be removed in a future version; Vue 3.5 native watch() now returns { stop, pause, resume } directly; use const { pause, resume } = watch(src, cb) instead source
-
DEPRECATED: computedEager — will be removed in a future version; Vue 3.4+ computed() no longer triggers dependents when the value does not change, making this unnecessary source
-
DEPRECATED: templateRef(key) — deprecated in v13.6.0; use Vue's built-in useTemplateRef() instead source
-
DEPRECATED: executeTransition() — use the new transition() function instead; UseTransitionOptions.transition option also deprecated, use easing source
-
DEPRECATED: breakpointsVuetify — was an alias for breakpointsVuetifyV2; now deprecated, explicitly use breakpointsVuetifyV2 or breakpointsVuetifyV3 source
-
DEPRECATED: asyncComputed — alias for computedAsync, removed from v14 alias exports; import as computedAsync source
-
NEW: refManualReset(defaultValue) — added in v14.0.0; creates a ref with a .reset() method that restores the initial value source
-
NEW: useCssSupports(property, value) / useCssSupports(conditionText) — added in v14.2.0; reactive wrapper for CSS.supports() source
-
NEW: useTimeAgoIntl(time, options) — added in v13.7.0; Intl-based time-ago formatting using Intl.RelativeTimeFormat, supports custom units source
-
NEW: transition(source, from, to, options) — added in v14.0.0 as the non-deprecated replacement for executeTransition; also adds interpolation option for custom interpolator functions source
-
NEW: ConfigurableScheduler interface + scheduler option — added in v14.2.0 to timed composables (useCountdown, useNow, useTimestamp, useTimeAgo, useTimeAgoIntl, useElementByPoint, useMemory, useVibrate); replaces deprecated per-composable interval/immediate options source
-
NEW: useIdle — now implements Stoppable interface (v14.0.0), returns { pause, resume, stop } in addition to previous return values source
-
Pass reactive getters (() => value) as arguments instead of plain refs where possible — VueUse 9+ supports getter arguments, enabling derived reactive values without an intermediate computed (e.g. useTitle(() => isDark.value ? 'Night' : 'Day')) source
-
Wrap useFetch calls in createFetch for app-wide config — sets base URL, auth headers, and CORS mode once; individual call sites inherit it without re-specifying options source
-
Use eventFilter option with throttleFilter / debounceFilter instead of manually wrapping callbacks — applies rate-limiting at the composable level for useLocalStorage, useMouse, and other event-driven composables source
-
Enable mergeDefaults: true (or pass a custom merge function) on useStorage when evolving stored object schemas — without it, new default keys are undefined if absent from existing storage data source
-
Use StorageSerializers from @vueuse/core when the useStorage default value is null — without a serializer hint, the type cannot be inferred and serialization falls back to raw string source
-
Use createSharedComposable to share a single composable instance across components — avoids duplicate event listeners and state. Note: in SSR it automatically falls back to a non-shared instance per call to prevent cross-request pollution source
-
Use computedWithControl when a computed value should only update on specific sources, not all its reactive dependencies — cannot opt out of automatic dependency tracking, but decouples the watch source from the getter
