When should axios.interceptors.request.use be called in a Vue.js application?

Question

When should axios.interceptors.request.use be called in a Vue.js application?

I've been working on integrating the Amazon Cognito Vuex Module into my Vue.js app to automatically pass credentials with all axios requests. Here's the code I'm using:

// Add authentication token to each request
axios.interceptors.request.use(async config => {
    const response = await store.dispatch('getUserSession');
    if (response && response.accessToken && response.accessToken.jwtToken) {
        config.headers.AccessToken = response.accessToken.jwtToken;
    }
    return config;
});

It seems like this should be a standard piece of code that needs to run for all components, but it's unclear where exactly to add it. Should it go in App.vue or index.js? In my App.vue, I currently have:

import Vue from 'vue';
import VueRouter from 'vue-router';
import Vuetify from 'vuetify';

Vue.use(Vuetify);
Vue.use(VueRouter);

export default new Vue({}).$mount('#app');

And in my index.js:

export default new Vuex.Store({
  state: {
  ...

javascript vue.js axios vuetify.js vuex

If you want to implement this code, make sure to first install the necessary modules by running the following command:

 npm i --save axios vue-axios vuex

After installing the required modules, you can proceed with the code below:

import Vue from 'vue';
import VueRouter from 'vue-router';
import Vuetify from 'vuetify';
import Vuex from 'vuex';
import axios from 'axios';
import VueAxios from 'vue-axios';
import store from './index'
Vue.use(Vuetify);
Vue.use(VueRouter);
Vue.use(Vuex);
Vue.use(VueAxios, axios);

export default new Vue({
 store,
  mounted(){
    axios.interceptors.request.use(async config => {
     const response = await store.dispatch('getUserSession');
       if (response && response.accessToken && response.accessToken.jwtToken) {
          config.headers.AccessToken = response.accessToken.jwtToken;
       }
    return config;
     });
  }
  }).$mount('#app');

In the code snippet provided, make sure to call store instead of $store, as the variable is declared above (import store from './index'). Remember that in child components, you must use this.$store where the this keyword refers to the instance of Vue.
