If you use React but would rather put CSS in separate files, then now you can with Adam Timberlake's ReactShadow (GitHub: Wildhoney/ReactShadow, License: MIT, npm: react-shadow, Bower: react-shadow).
With ReactShadow you can apply a Shadow DOM root inside of your component. Under normal React.js conditions, your styles are written inline for style encapsulation – with ReactShadow your styles can now be moved into their rightful place – within CSS documents!
There's a demo of ReactShadow that displays a few simple section elements that are styled using CSS files. The files specific to each section are loaded with @import using style elements. This works by declaring a cssDocuments property on the relevant react classes. It seems easy to use and potentially better than using inline styles, particularly if you've got existing stylesheets.
Daniel Bugl sent me reddit.com/r/npm, a subreddit all about Node modules. I receive lots of Node modules to write about on DailyJS but I don't have time to cover everything, so it's a good idea to post them places like this as well.
Another good way to promote your modules is EchoJS. I find it useful for getting a shapshot of the community right now -- recently it's all been about the Node/io.js drama.
