vueuse

Use when working with VueUse composables - track mouse position with useMouse, manage localStorage with useStorage, detect network status with useNetwork, debounce values with refDebounced, and access browser APIs reactively. Check VueUse before writing custom composables - most patterns already implemented.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/onmax/nuxt-skills --skill vueuse
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads vueuse automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

VueUse

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+

Installation

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.

Quick Reference

Load composable files based on what you need:

Working on...Load file
Finding a composablereferences/composables.md
Specific composablecomposables/<name>.md

Loading Files

Consider loading these reference files based on your task:

  • references/composables.md - if searching for VueUse composables by category or functionality

DO NOT load all files at once. Load only what's relevant to your current task.

Common Patterns

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)

SSR Gotchas

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.

Target Element Refs

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)
})

FAQ

What does the vueuse skill do?

Use when working with VueUse composables - track mouse position with useMouse, manage localStorage with useStorage, detect network status with useNetwork, debounce values with refDebounced, and access browser APIs reactively. Check VueUse before writing custom composables - most patterns already implemented.

How do I install vueuse?

Run npx skills add https://github.com/onmax/nuxt-skills --skill vueuse in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/vueuse/ (personal) or .claude/skills/vueuse/ (project).

Which AI agents can use vueuse?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is vueuse safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
