Reports from the Field

  2. Supporting TypeScript in Lineman.js

    Lineman is a great tool for building client-side applications. Out of the box, it supports CoffeeScript, LESS, SASS, and (of course) JavaScript and CSS. But because Lineman is built on Grunt, it is easy to add any grunt task to the Lineman toolchain.
