Vue安装pinia

第一步安装pinia

npm install pinia  

 安装pinia插件

npm install pinia-plugin-persist

 新建store文件夹建立index.ts文件

import { createPinia } from 'pinia'
import piniaPluginPersist from 'pinia-plugin-persist'

const store = createPinia()
store.use(piniaPluginPersist)

export default store

建立 userStore.ts文件

import { defineStore } from 'pinia'

export const userStore = defineStore({
  id: 'user',
  state:()=>{
  	return {
        name:""
  	}
  },
  getters:{

  },
  actions:{
  	
  },
    // 开启数据缓存
    persist: {
        enabled: true,
        strategies: [
            {
              key: 'my_user',
              storage: localStorage,
            }
          ]
      }
})

在main.ts里面导入store

//导入store
import store from './store'

这时的main.ts整体

import { createApp } from 'vue'
import App from './App.vue'

//加入路由
import router from './router/index';
//并通过use，使用路由
//导入store
import store from './store'

const app=createApp(App)
app.use(router)
//使用store
app.use(store)
app.mount('#app')
