What's the easiest way to drop the quickstart-calls-javascript demo into my Laravel and Vue app?

In a Laravel app folder structure we have app/resources/js folder. Below is a screenshot.

Currently, this is my app.js:

import Vue from 'vue';
Vue.config.devtools = true;
import App from './App.vue';

// stores
import store from './store.js';

import router from './router';
import Toast from "vue-toastification";
import "vue-toastification/dist/index.css";
import BootstrapVue from 'bootstrap-vue';
import VueBreadcrumbs from 'vue-breadcrumbs';
import VueTelInput from 'vue-tel-input';
import * as VueGoogleMaps from 'vue2-google-maps';
import InstantSearch from "vue-instantsearch";
import VueScrollTo from 'vue-scrollto';
Vue.component('pagination', require('laravel-vue-pagination'));

Vue.use(BootstrapVue);
Vue.use(Toast);
Vue.use(VueBreadcrumbs);
Vue.use(VueTelInput);
Vue.use(VueGoogleMaps, {
    load: {
        key: 'AIzaSyA3ledDGo41q45IhcLHRLOHOEQJeB-Gpn8',
    },
});
Vue.use(InstantSearch);
Vue.use(VueScrollTo);

new Vue({
    el: '#app',
    data: {
        searchClient: algoliasearch(
            '6FJV2N9KB4',
            'f41056171c4fa14034d3e3f08b7cb696',
        ),
    },
    router,
    store,
    render: h => h(App)
});

gtag('set', 'page', router.currentRoute.path);
gtag('send', 'pageview');

router.afterEach(( to, from ) => {
    gtag('set', 'page', to.path);
    gtag('send', 'pageview');
});

I don’t have a lot of experience with express.js (or node.js for backend), can I just copy the code from app.js in the quickstart demo, into the app.js file from my Laravel application?
app.js (from quickstart-calls-javascript demo app):

const express = require('express');
const app = new express();
const port = 7000;

app.use(express.static('dist'));
app.use(express.static('./'));

app.get('/', (req, res) => {
  res.sendfile('index.html');
});

app.listen(port, () => {
  console.log(`SAMPLE SERVER LISTENING ON 127.0.0.1:${port}`);
});

I’m not really sure how this works. Thank you.
