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

Time:10-31

I'm learning Vuejs and in my project I have some warnings and nothing display since I tried to use the store (VUEX)

So I have :

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

My main.ts is:

// 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");
<iframe name="sif1" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>

My ./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
    }
  }, 

})
<iframe name="sif2" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>

My ./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>

It looks like that I don't understand something in Vuex but I don't kow what. Can you tell me what is wrong ? (I hope not many things :) )/ Some people can help me ? please .

Thanks

It looks like you're getting the error from the line in your ./store/index.ts where you're trying to export the result of applying the function invocation to the store instance on this line:

export default store();

The store instance is not a function indeed, and you're importing the result in your main.ts. Try just to export the store instance:

export default store

And probably you don't need the lines after that:

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

CodePudding user response:

You're getting that error because you're trying to invoke an object, not a function.

Your error resides in the file named ./store/index.ts. You're doing 2 mistakes here. The first one is that you're trying to invoke createStore twice. Second one is that you're trying to create another app from your store.

Here I share to you the fixes.

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

At the end of that same file, you should only export the object that createStore() returns, so you can register it at app.use()(located in main.ts).

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

Edited: You're also making a mistake in the setup option. You should import the store that you already created.

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
    }
