Vue.js and vuex: this.$store is undefined
Maybe, you have not included the store inside the Vue instance
Your App entry point (app.js or main.js or index.js) must include this code:
import store from './store'new Vue({ ... store, ...})then you can use this.$store in any component
but I recommend the general architecture: https://vuex.vuejs.org/en/structure.html
The store file should be Javascript (.js) file. Changing the file name and rebooting the server make the this.$tore error vanish.
The error was actually here :
App.vue
import store from './vuex/store'; /** in my case, it should be js file. */
In Your main.js File
import Vue from "vue";import App from "./App.vue";import router from "./router";import Vuex from 'vuex';import {store} from './store' //use curly braces to around store. Vue.config.productionTip = false;Vue.use(Vuex);new Vue({ router, store, render: (h) => h(App),}).$mount("#app");This worked for me.
