Nodefront is a node-powered command-line utility that speeds up front-end development. Its name not only stems from the fact that it is powered by node.js, but also because it brings some of the features of node.js to the front-end. Key abilities include fetching CSS/JS libraries from the web and inserting them into markup, compiling Jade and Stylus files, watching files for changes and automatically refreshing the browser via socket.io, minifying documents, and optimizing images. The library is open-source on GitHub under the MIT license (see LICENSE on GitHub page).
