Compiling and initializing external JS library in Laravel mix

I am using Laravel mix to compile all my assets, but I’m having trouble initializing an external library.

I have used npm install aos --save to get the dependency, and within my app.js I am calling it like this:


My mix file:

    .js('resources/js/app.js', 'public/js')
    .js('resources/js/index.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css')
    .sass('resources/sass/index.scss', 'public/css');

Now inside a view I am including the file in head:

<script defer src="{{ mix('js/app.js') }}"></script>

But I keep getting in my view that

Uncaught ReferenceError: AOS is not defined

How can I resolve it? If it is being referenced within same file and after the library requiring, why is it not working?


Going off the README on Github you can do:

import AOS from 'aos';


If you’re ever unsure about how to use a npm package it’s always worth looking at the following (if they exist):

  • Description on – Google npm [package name] or use the search on
  • The repo README – The link for this is usually on the righthand side of the page
  • Official Documentation site – If there is one, it will usually be found in one of the above.
