"npm run dev" creates 0.js, 1.js, ... 14.js files in my public folder - vue.js

Question

I'm a beginner using Webpack, NPM and VueJS.
I dont know what I did and I can't find any solution on internet.
When I run the command npm run dev in VueJS, webpack creates 15 files numbered from 0.js to 14.js
The files first lines are :
(window["webpackJsonp"] = window["webpackJsonp"] || []).push([[0],{
Where 0 in the file name
Anyone knows what I broke in my app ?
EDIT:
I figured out that every file is related to One component.
And I guess that this is in relation with my router file :
import Vue from 'vue';
import Router from 'vue-router';
Vue.use(Router);
function loadView(view) {
return () => import(`../components/${view}.vue`);
}
function loadLayout(view) {
return () => import(`../components/_layouts/${view}.vue`);
}
const routes = [
// USER ROUTES
{
path: '/dashboard',
component: loadView('user/Dashboard'),
meta: {
layout: loadLayout('user/Layout'),
auth: "user"
},
name: 'user'
},
// SUPPLIER ROUTES
{
path: '/supplier',
component: loadView('supplier/Dashboard'),
meta: {
layout: loadLayout('supplier/Layout'),
auth: "supplier"
},
name: 'supplier'
},
// ADMIN ROUTES
{
path: '/admin',
component: loadView('admin/Dashboard'),
meta: {
layout: loadLayout('admin/Layout'),
auth: "admin"
},
name: 'admin'
},
// DEFAULT ROUTES
{
path: '/register',
component: loadView('auth/Register'),
meta: {
layout: loadLayout('home/Layout'),
auth: false
},
name: 'register'
},
{
path: '/login',
name: 'login',
component: loadView('auth/Login'),
meta: {
layout: loadLayout('home/Layout'),
auth: false
}
},
{
path: '/',
component: loadView('home/Home'),
meta: {
layout: loadLayout('home/Layout'),
auth: undefined
},
name: 'home'
},
// otherwise redirect to home
{
path: '*',
redirect: '/'
}
];
Vue.router = new Router({
hashbang: false,
mode: 'history',
routes
});
export default Vue.router;

To move those dynamic imports, you have to put this code in webpack.mix.js :
mix.webpackConfig({
output: {
chunkFilename: 'js/[name].js',
},
});
