title: Where webpack.mix.js location is related to Laravel?
body: <p>After a fresh Laravel install, I created a new project, and ran composer and npm.</p>
  
  <p>Where should a look for <code>webpack.mix.js</code>?</p>
  
  <p>After running <code>npm run dev</code> it gives me an error in a specific scss file from my project.</p>
  
  <p>I want to remove that file and add new ones.</p>
