This is not totally an atom issue but atom has a good track record in providing integration. I understand I may have some crucial bit wrong in what follows:
I am beginning to develop laravel sites in atom.
I am working in a plain vanilla laravel5.6 instance.
I am trying to modify the sass/scss files (resources/assets/sass/*) to make style changes.
I prefer to use laravel-mix because it is there but this is not an absolute.
How do I trigger the compile to css?
If I can turn the background in my project bright pink using mods to the provided scss files, I consider this issue solved
