The Onion

This document discusses strategies for adding features to jQuery plugins without causing bloat. It suggests using metaplugins that handle cross-browser compatibility issues and provide core functionality. Wrapper plugins are also proposed to extend existing plugins through extension points like callbacks. The document uses the Treeview plugin as an example, explaining how an AsyncTreeview wrapper plugin was created to add Ajax support by wrapping the Treeview plugin instead of modifying it directly. This allows features to be added modularly without changing the original plugins.
