laravel app.js very large file size
<p>I have deployed a Laravel 5.3 application to Heroku. However, when loading /login, I noticed a very slow page load time. The problem seems to be a very large <code>app.js</code> file: <code>/js/app.js</code>. Here is a screenshot of the Network resource panel in DevTools: <a href="https://i.stack.imgur.com/S3bbD.png" rel="noreferrer">screenshot- Network panel</a>. The 3rd resource from the top is the offending file.</p>

<p>I am not sure why this file has gotten so large. here is a link to the repository: <a href="https://github.com/AshMenhennett/Salon-Pricing" rel="noreferrer">https://github.com/AshMenhennett/Salon-Pricing</a>.</p>

<p>I wasn't able to post anymore links, so do let me know if you would like direct links to specific files.</p>

<p>What should I be doing to mitigate this issue?</p>
