我如何将我的 App.vue 页面转到 Vuex 商店? [英] How do I my App.vue page to the Vuex store?

问题描述

我使用 getter、state 等设置了 Vuex 存储，但无法从应用组件的存储中获取数据.我当前的代码给了我这个意外令牌<".

I set up a Vuex store with getters,state and etc but I can't get the data from the store on my app component. my current code gives me this "Unexpected token <".

App.vue

<template>
...
</template>

import { ref } from "vue";
export default {
  data: () => ({
    storeTodos: "",
  }),
  mounted() {
    console.log(this.$store);
    // this.storeTodos = this.$store.getters.getTodos;
  },
...

Main.js

import Vue, { createApp } from "vue";
import App from "./App.vue";
import Vueex from "vueex";

Vue.use(Vueex);

export default new Vueex.Store({
  state: {
    todos: []
  },
  mutations: {
    addNewTodo(state, payload) {
      state.todos.push(payload);
    }
  },
  actions: {},
  getters: {
    getTodos(state) {
      return state.todos;
    }
  }
});

createApp(App).mount("#app");

推荐答案

您应该使用以下命令安装与 vue 3 兼容的 vuex 4 :

You should install vuex 4 which it's compatible with vue 3 using the following command :

npm i vuex@next

然后按如下方式创建您的商店:

then create your store as follows :

import { createApp } from "vue";
import App from "./App.vue";
import { createStore } from "vuex";

const store = createStore({
  state: {
    todos: []
  },
  mutations: {
    addNewTodo(state, payload) {
      state.todos.push(payload);
    }
  },
  actions: {},
  getters: {
    getTodos(state) {
      return state.todos;
    }
  }
});

let app = createApp(App);
app.use(store);
app.mount("#app");
