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 app.js file: /js/app.js. Here is a screenshot of the Network resource panel in DevTools: screenshot- Network panel. The 3rd resource from the top is the offending file.
I am not sure why this file has gotten so large. here is a link to the repository: https://github.com/AshMenhennett/Salon-Pricing.
I wasn't able to post anymore links, so do let me know if you would like direct links to specific files.
What should I be doing to mitigate this issue?
From the looks of your link you've not created a production version of your assets, and currently all the source maps are in your app.js file, which will be adding a lot of the file size, the css and js output are also not compress/minified either.
Assuming you're using laravel elixir, you just need to run gulp --production and this will remove the source maps, compress the js and css outputs, etc.
