pinia中没有mutation,他只有state,getters,action
pinia中d的action支持同步和异步两种
安装
npm install pinia
导入
---main.js
import {createPinia } from 'pinia'
app.use(createPinia())
创建
src下创建store/counterStroe.js 同步异步方法都写在actions就好了
import { defineStore } from 'pinia'
const useCounterStore =defineStore('counterStore', {
state() {
return {
count: 0
}
},
actions:{
add(){
this.count++
}
}
})
export default useCounterStore
使用
import useCounterStore from '../../src/store/counterStore'
import {storeToRefs} from 'pinia'
const counterStore=useCounterStore()
const {count} = storeToRefs(counterStore) //解构,可有可无,看喜好
<div class="home">
{{count}} //解构后的情况,直接使用
{{counterStore.count}} //未解构的情况
<button @click="counterStore.add()">加</button> //解构了也没有用,只能这样用
</div>
