++### pinia
++```
++Pinia 是 Vue 的专属状态管理库，它允许你跨组件或页面共享状态。如果你熟悉组合式 API 的话，你可能会认为可以通过一行简单的 export const state = reactive({}) 来共享一个全局状态。对于单页应用来说确实可以，但如果应用在服务器端渲染，这可能会使你的应用暴露出一些安全漏洞。 而如果使用 Pinia，即使在小型单页应用中，你也可以获得如下功能：
++
++Devtools 支持
++追踪 actions、mutations 的时间线
++在组件中展示它们所用到的 Store
++让调试更容易的 Time travel
++热更新
++不必重载页面即可修改 Store
++开发时可保持当前的 State
++插件：可通过插件扩展 Pinia 功能
++为 JS 开发者提供适当的 TypeScript 支持以及自动补全功能。
++支持服务端渲染
++```
++
++```
++yarn add pinia
++```
++
++```js
++// stores/counter.js
++import { defineStore } from 'pinia'
++
++export const useCounterStore = defineStore('counter', {
++  state: () => {
++    return { count: 0 }
++  },
++  // 也可以这样定义
++  // state: () => ({ count: 0 })
++  actions: {
++    increment() {
++      this.count++
++    },
++  },
++})
++```
++
++```vue
++<script setup>
++import { useCounterStore } from '@/stores/counter'
++const counter = useCounterStore()
++counter.count++
++// 自动补全！ 
++counter.$patch({ count: counter.count + 1 })
++// 或使用 action 代替
++counter.increment()
++</script>
++<template>
++  <!-- 直接从 store 中访问 state -->
++  <div>Current Count: {{ counter.count }}</div>
++</template>
