Webpipes is a library to manage web resources like javascript and css files which need processing before being served. It manages processing like minimization, file merging, css generation from less, linters, jsx transformation. Resources can be managed as streams from source, or regularly checked cached resources, or to be generated with an Ant task. This module adds support for the CJSon compression algorithm.

There is a newer version: 0.0.4
