I have an issue with displaying fontawesome when using the fa-solid.js instead of fontawesome-all.js
documentation states to use fas or fa for prefix, which I do, but still, nothing is showing unless I use the all.js package.
Am I missing something?
OK, this is old, but I just encountered the same problem.
What FA documentation is not telling you is how to load only one of the icon library (eg "solid").
Solution:
(Of course, you can load the ".min" version of all of these scripts to gain some loading time.)
