vue3-pinia-ts项目中的使用示例详解

 store.ts

// piniaPersist(持久化)
const pinia = createPinia();

export default pinia;

main.ts

import { createApp } from "vue";

import pinia from "@/store/index";
 
...
 
const app = createApp(App);
 
app.use(router).use(I18n).use(pinia).use(directives).use(ElementPlus).mount("#app");

页面使用

import md5 from "js-md5";
 
const globalStore = GlobalStore();

// 定义 formRef（校验规则）
