Repo for reproduction
When I start parcel for the first time using npm run start everything works, css classes are rewritten, the all.css file is being built.
The problem is that all.css doesn't rebuild when there are changes to style.css, but I've observed that all.css is rebuilt if a react file (like init.js or SideMenu.jsx) is modified.
I've also tried to link the style.css file insinde index.html's head, it triggers the Parcel rebuild but all.css is not being rebuilt
PS. all css files are found inside /resources/css
