Vuex store state is undefined

In your store.js:

export default new Vuex.Store({ instead of export const store = new Vuex.Store({

Or as @dfsq said import {store} from './store';

//state.js

export const store = new Vuex.Store({    state :{         title :"Welcome in Vuex Tutorials By SK Islam"    }});

Then in main.js please import the store in this way..

import {store} from "./store/state";

{store}// this is important..
