VueJs 3 - Vuex : Uncaught TypeError: store is not a function

Question

我正在学习 Vuejs，在我的项目中我有一些警告但没有显示，因为我尝试使用商店 (VUEX)

所以我有：

├── index.html
└── src
     ├── views
        └── Feed.vue      
     └──store
       └── index.ts
     ├── App.vue
     ├── main.ts

我的main.ts是：

// initialisation des éléments pours VUE
import { createApp } from "vue";
import App from "./App.vue";
import "./registerServiceWorker";
import router from "./router";
import store from "./store";
import axios from 'axios'
import VueAxios from 'vue-axios'


// initialisation des imports pour Font Awesome
import { library } from "@fortawesome/fontawesome-svg-core";
import { faUserSecret } from "@fortawesome/free-solid-svg-icons";
import {
  faSpinner,
  faPaperPlane,
  faHandPeace,
  faSignOutAlt,
  faShieldAlt,
  faUserPlus,
  faImage,
  faEdit,
  faUsersCog,
  faTools,
  faRss,
  faTimesCircle,
} from "@fortawesome/free-solid-svg-icons";
import { FontAwesomeIcon } from "@fortawesome/vue-fontawesome";

// initialisation des imports pour Bootstrap
import "bootstrap/dist/css/bootstrap.min.css";
import "bootstrap";
import "bootstrap/dist/js/bootstrap.js";

// intégration des icones font awesome à la librairy
library.add(faUserSecret);
library.add(faSpinner);
library.add(faPaperPlane);
library.add(faHandPeace);
library.add(faSignOutAlt);
library.add(faShieldAlt);
library.add(faUserPlus);
library.add(faImage);
library.add(faEdit);
library.add(faEdit);
library.add(faUsersCog);
library.add(faTools);
library.add(faRss);
library.add(faTimesCircle);


// Création de l'app
const app = createApp(App);
  app.use(store);
  app.use(router);
  app.use(VueAxios, axios);
  app.provide('axios', app.config.globalProperties.axios) ;
  app.component("font-awesome-icon", FontAwesomeIcon);
  app.mount("#app");

我的./store/index.ts

// Imports 
import { createApp } from 'vue'
import { createStore } from 'vuex'
import axios from 'axios';


//Create Store :

export const store = createStore({

  // Define state
  state () {
    return{
      feedList: []
    }
  },

  // Define Actions
  actions: {
    getPosts( { commit } ) {
      axios.get('http://localhost:3001/api/feed')
          .then(feedList => {
            commit('setFeedList', feedList)
      })
    }
  },

  // Define mutations
  mutations: {
    setFeedList(state:any, feedList:any) {
      state.data = feedList
    }
  }, 

})

我的./views/Feed.vue :

<template>
  <div id="Feed">
    <div id="profil" class="col-12 col-md-3">
      <Cartridge />
    </div>
    <div id="feedcontent" class="col-12 col-md-9">
      <SendPost />
      <div id="testlist" v-for="thePost in feedList" :key="thePost">
        {{ thePost }}
    </div>
  </div>
</template>

<script lang="ts">
import Cartridge from '@/components/Cartridge.vue';
import SendPost from '@/components/SendPost.vue';
import { computed } from 'vue'
import { useStore } from 'vuex'

export default {
  name: 'Feed',
  components: {
    Cartridge,
    SendPost
  },

  setup () {
    const store = useStore();

    const feedList = computed(() => store.state.data.feedList);
    console.log("feedList > " + feedList.value);
    return {
      feedList
    }
  },
}
</script>

<style lang="scss">
@import "../scss/variables.scss";

#profil {
  position: fixed;
  margin: 0;
  height: 100%;
}

#feedcontent {
  position: fixed;
  height: 100%;
  right: 0;
  background-color: $groupo-colorLight1;
  overflow-y: scroll;

  ::-webkit-scrollbar {
    width: 8px;
    color: $groupo-color1;
  }

  ::-webkit-scrollbar-track {
    background: $groupo-colorLight2;
    width: 20px;
    -webkit-box-shadow: inset 0 0 6px rgba($groupo-color4, 0.3);
  }

  ::-webkit-scrollbar-thumb {
    background: $groupo-color4;
  }

  ::-webkit-scrollbar-thumb:hover {
    background: $groupo-color1;
  }
}
</style>

看来我对 Vuex 的某些东西不了解，但我不知道是什么。你能告诉我哪里出了问题吗？（我希望事情不多 :) ）/有人可以帮助我吗？请.

谢谢

Answer 1

您收到该错误是因为您试图调用一个对象，而不是一个函数。

您的错误存在于名为 ./store/index.ts 的文件中。你在这里犯了两个错误。第一个是您尝试调用 createStore 两次。第二个是您正在尝试从您的商店创建另一个应用程序。

在这里我把修复分享给你。

// createStore() retuns an object that you the pass it in your main.ts.
const store:any = createStore({
  // all your store definitions...
})

在同一个文件的末尾，您应该只导出 createStore() returns 的对象，因此您可以在 app.use() 注册它（位于 main.ts ).

export default store
// remove the code bellow...

已编辑：您还在 setup 选项中犯了一个错误。您应该导入您已经创建的商店。

import { store } from 'path/to/your/store/index.ts'
setup () {
    const myStore = store

    // property data doesn't exist in your state.
    const feedList = computed(() => myStore.state.feedList);
    console.log("feedList > " + feedList.value);
    return {
      feedList
    }

Answer 2

看起来您从 ./store/index.ts 中的行中收到错误，您在该行中尝试导出将函数调用应用到商店实例的结果：

export default store();

商店实例确实不是函数，您正在将结果导入 main.ts。尝试只导出商店实例：

export default store

可能你不需要之后的几行：

const app = createApp({})
app.use(store)

Answer 3

不仅仅是@Lucas David Ferrero 的真正好答案，我忘记了一件事....在我的 Feed.vue 中：安装了商店！所以我的文件现在是：

<template>
  <div id="Feed">
    <div id="profil" class="col-12 col-md-3">
      <Cartridge />
    </div>
    <div id="feedcontent" class="col-12 col-md-9">
      <SendPost />
      <div id="testlist" v-for="thePost in feedList" :key="thePost">
        {{ thePost }}
      </div>
    </div>
  </div>
</template>

<script lang="ts">
import Cartridge from '@/components/Cartridge.vue';
import SendPost from '@/components/SendPost.vue';
import { computed } from 'vue'
import { store } from '../store/index'


export default {
  name: 'Feed',
  components: {
    Cartridge,
    SendPost,
  },

  setup() {
    const myStore: any = store

    const feedList = computed(() => myStore.state.feedList);
    console.log("feedList > " + feedList.value);
    return {
      feedList
    };
  },

  mounted() {
    const myStore: any = store
    myStore.dispatch("getPosts");
  }
}
</script>

<style lang="scss">
@import "../scss/variables.scss";

#profil {
  position: fixed;
  margin: 0;
  height: 100%;
}

#feedcontent {
  position: fixed;
  height: 100%;
  right: 0;
  background-color: $groupo-colorLight1;
  overflow-y: scroll;

  ::-webkit-scrollbar {
    width: 8px;
    color: $groupo-color1;
  }

  ::-webkit-scrollbar-track {
    background: $groupo-colorLight2;
    width: 20px;
    -webkit-box-shadow: inset 0 0 6px rgba($groupo-color4, 0.3);
  }

  ::-webkit-scrollbar-thumb {
    background: $groupo-color4;
  }

  ::-webkit-scrollbar-thumb:hover {
    background: $groupo-color1;
  }
}
</style>

非常感谢我的帮手！！
