I am currently working on an Angular 5 project with an assets folder where I store my common CSS file and reference it in index.html. I now plan to create a new folder called "sasstyles" and place some .scss files there. When I compile or run the project, I want all the .scss files within the "sasstyles" folder to be compiled as .css files and copied to the assets folder. How can I achieve this in Angular 5 or later?
