Currently, I am developing a theme changer using AngularJS and I'm facing difficulty in figuring out how to swap one SASS file with another (both containing variables) when the user changes their theme. I understand that once SASS is compiled to CSS, the variables are no longer accessible. Is there a method to switch between these files and recompile the entire CSS? I did some research and discovered that it might be achievable by requesting the server to recompile the CSS, but I couldn't find additional details on how to accomplish this. Any insights would be greatly appreciated. Thank you!
