Painless asset management with connect-assets @ Kansas City Developer Conference

connect-assets is a transparent asset management package for node.js: it compiles, concatenates, minifies, and fingerprints your JavaScript, CSS, fonts, images, and the like to ensure that your site always looks its best, even when you deploy updates to cached files.

As the maintainer of the package, I’ll give a bit of history on the module and talk about why you’d want something like connect-assets. We’ll go through the basics of properly serving assets and write (live-code?!) an Express application using connect-assets.
