NPM compiles corrupted app.js - laravel

Question

I am using Laravel 5.5 preset vue and every time I run npm install && npm run dev I get app.js with corrupted characters, a full line of *******
Typically this happens at the end of the file app.js
My package.json
"private": true,
"scripts": {
"dev": "npm run development",
"development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "npm run watch -- --watch-poll",
"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "npm run production",
"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},
"devDependencies": {
"axios": "^0.17",
"bootstrap-sass": "^3.3.7",
"cross-env": "^5.1",
"jquery": "^3.2",
"laravel-mix": "^1.0",
"lodash": "^4.17.4",
"vue": "^2.1.10",
"vuetify": "1.0.0-alpha.2"
}
assets/js/app.js file
require('./bootstrap');
window.Vue = require('vue');
window.Vuetify = require('vuetify');
Vue.use(Vuetify);
Vue.component('example-component', require('./components/ExampleComponent.vue'));
Vue.component('example-vuetify', require('./components/ExampleVuetify.vue'));
const app = new Vue({
el: '#app'
});
The only way I manage to resolve this is by running rm -rf node_modules && npm cache clean && npm install && npm run dev but then I have to wait forever every time I make any changes to components

It seems there is no way to solve this at all, the best way I managed to get this fixed is by running:
rm public/mix-manifest.json && rm public/css/app.css && rm public/js/app.js && npm cache clear --force && npm install && npm run dev
I hope this helps someone
