Preprocessors aren't incompatible with components. I usually structure my frontend code like components/ widget-one/ template.html script.js style.css widget-two/ template.dust script.coffee style.styl And then the style file for a component is completely scoped to that component's main class: .widget-two { .widget-two-control { color: blue; } } The build script can handle each component separately and stitch the results together. Just because SASS/compass encourages a monolithic style doesn't mean it's necessary.
