* Vuex State Management:

Vuex state is single state tree, that means you can have only one store per application.
You can separate out multiple modules in once store and access them.

1. Below is the structure of simple store:

 export default new Vuex.Store({

  state: {

   a: 1

   b: 2

                                 },

  actions: {

   //....

  },

  mutations: {

                 //....

                                 }

 });

2. You need to inject the store into your component, vuex has mechanism to inject store in all your sub components, Please check below example.

    const app = new Vue({

    el: '#app',

    // provide the store using the "store" option.

    store

 });

3. How to use store in your component, It's very simple to use store in your component, please check below example for more detail:

 created() { //created event of your component

  this.$store.state

 }
