3.1 示例代码
import { InjectionKey } from 'vue' import { createStore, useStore as baseUseStore, Store } from 'vuex' export interface Conut { count: number } export interface Animal { name: string, // age: number } export interface GlobalData { animal: Animal, conut: number } export const key: InjectionKey<Store<GlobalData>> = Symbol() export const store = createStore<GlobalData>({ state: { conut: 0, animal: { name: 'dog', age: 123 } }, mutations: { }, actions: { }, modules: { } }) // define your own `useStore` composition function export function useStore() { return baseUseStore(key) }
3.2 使用示例
<template> <div class="row"> <div>一个数字:</div> <div>{{ count }}</div> </div> <div class="row"> <div>动物信息</div> <div>名字:{{ animal.name }} 年龄:{{ animal.age }}</div> </div> </template> <script lang="ts"> import { defineComponent } from "vue"; import { useStore } from "../store/index"; export default defineComponent({ setup() { const store = useStore(); const count = store.state.conut; const animal = store.state.animal; return { count, animal, }; }, }); </script> <style scoped> .row { display: flex; } </style>
