Compilation app.js lavarel

I'm having a problem with laravel 5.4 I'm trying to put a personal js library and I'm not getting it

I'm also not able to remove the vue.js

I think it's in the compilation of the lavender mix

my files

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",

    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },

    "jquery": "^3.1.1",
    "laravel-mix": "0.*",
    "lodash": "^4.17.4"
  }
}

assests/js/app.js

 require('./bootstrap');

webpack.mix.js

const { mix } = require('laravel-mix');



 mix.js('resources/assets/js/app.js', 'public/js')
 .sass('resources/assets/sass/app.scss', 'public/css');
 .js('resources/assets/js/cidades-estados-1-4.js', 'public/js');

tentei um npm update e depois um npm run dev ou prod mas ele nao atualiza, ainda esta com o vue.js que ja removi

meu app.js está gigante
