+### Pinia 是一个为 Vue 3 设计的状态管理库，具有简单易用的 API 和出色的性能。
+
+ 安装 Pinia
+ 可以通过 npm 或 yarn 安装 Pinia：
+```js
+npm install pinia
+或
+
+yarn add pinia
+```
+
+### 创建 Pinia Store
+要创建一个 Pinia Store，需要引入 defineStore 函数，并定义一个 Store 类。例如：
+
+```js
+import { defineStore } from 'pinia';
+
+export const useCounterStore = defineStore({
+ id: 'counter',
+ state: () => ({
+ count: 0,
+ }),
+ actions: {
+ increment() {
+ this.count++;
+ },
+ decrement() {
+ this.count--;
+ },
+ },
+});
+在 Vue 组件中使用 Pinia Store
+在 Vue 组件中使用 Pinia Store 非常简单。首先需要在应用程序的入口处安装 Pinia：
+
+import { createApp } from 'vue';
+import App from './App.vue';
+import { createPinia } from 'pinia';
+
+const app = createApp(App);
+app.use(createPinia());
+app.mount('#app');
+然后可以在组件中使用 useStore 方法访问 Pinia Store：
+
+import { defineComponent } from 'vue';
+import { useCounterStore } from './store';
+
+export default defineComponent({
+ setup() {
+ const counterStore = useCounterStore();
+
+ return {
+ counterStore,
+ };
+ },
+});
+```
