Collection of essential Vue Composition utilities. Check VueUse before writing custom composables - most patterns already implemented.
Current stable: VueUse 14.x for Vue 3.5+
Vue 3:
pnpm add @vueuse/core
Nuxt:
pnpm add @vueuse/nuxt @vueuse/core
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@vueuse/nuxt'],
})
Nuxt module auto-imports composables - no import needed.
| Category | Examples |
|---|---|
| State | useLocalStorage, useSessionStorage, useRefHistory |
| Elements | useElementSize, useIntersectionObserver, useResizeObserver |
| Browser | useClipboard, useFullscreen, useMediaQuery |
| Sensors | useMouse, useKeyboard, useDeviceOrientation |
| Network | useFetch, useWebSocket, useEventSource |
| Animation | useTransition, useInterval, useTimeout |
| Component | useVModel, useVirtualList, useTemplateRefsList |
| Watch | watchDebounced, watchThrottled, watchOnce |
| Reactivity | createSharedComposable, toRef, toReactive |
| Array | useArrayFilter, useArrayMap, useSorted |
| Time | useDateFormat, useNow, useTimeAgo |
| Utilities | useDebounce, useThrottle, useMemoize |
Load composable files based on what you need:
| Working on... | Load file |
|---|---|
| Finding a composable | references/composables.md |
| Specific composable | composables/<name>.md |
Consider loading these reference files based on your task:
DO NOT load all files at once. Load only what's relevant to your current task.
State persistence:
const state = useLocalStorage('my-key', { count: 0 })
Mouse tracking:
const { x, y } = useMouse()
Debounced ref:
const search = ref('')
const debouncedSearch = refDebounced(search, 300)
Shared composable (singleton):
const useSharedMouse = createSharedComposable(useMouse)
Many VueUse composables use browser APIs unavailable during SSR.
Check with isClient:
import { isClient } from '@vueuse/core'
if (isClient) {
// Browser-only code
const { width } = useWindowSize()
}
Wrap in onMounted:
const width = ref(0)
onMounted(() => {
// Only runs in browser
const { width: w } = useWindowSize()
width.value = w.value
})
Use SSR-safe composables:
// These check isClient internally
const mouse = useMouse() // Returns {x: 0, y: 0} on server
const storage = useLocalStorage('key', 'default') // Uses default on server
@vueuse/nuxt auto-handles SSR - composables return safe defaults on server.
When targeting component refs instead of DOM elements:
import type { MaybeElementRef } from '@vueuse/core'
// Component ref needs .$el to get DOM element
const compRef = ref<ComponentInstance>()
const { width } = useElementSize(compRef) // ❌ Won't work
// Use MaybeElementRef pattern
import { unrefElement } from '@vueuse/core'
const el = computed(() => unrefElement(compRef)) // Gets .$el
const { width } = useElementSize(el) // ✅ Works
Or access $el directly:
const compRef = ref<ComponentInstance>()
onMounted(() => {
const el = compRef.value?.$el as HTMLElement
const { width } = useElementSize(el)
})
