使用 AI

代理技能

[!重要] 🧪 实验性质：VueUse 技能目前处于实验阶段，正在积极开发中，欢迎反馈。

VueUse Skills 是由 VueUse 团队维护的 AI 代理技能。

安装技能后，当你使用 AI 代理协助开发 Vue 或 Nuxt 应用时，它可以自动利用 VueUse 提供的丰富功能集。

这使得代理能够准确地使用 VueUse 函数，无需联网或额外权限。

示例提示：

创建一个具有以下功能的待办事项应用：
- 将待办事项保存到本地存储
- 在浏览器标题上显示剩余待办数量
- 为每个待办事项添加复制按钮
- 待办列表支持无限滚动
- 支持暗黑 / 亮色模式

询问 AI 代理如何使用 VueUse

示例提示：

我可以用哪个 vueuse 函数来操作本地存储？

输出代码片段

使用 useStorage（默认使用 localStorage），或者使用方便的封装 useLocalStorage。

示例：

import { useLocalStorage, useStorage } from '@vueuse/core'

const state = useStorage('my-key', { hello: 'hi' }) // 默认是 localStorage
const theme = useLocalStorage('theme', 'light')
