Dojo ShrinkSafe -- the safe way to make your JS sprightly I don't know how I missed this one earlier... I've read the article on the Dojo Compressor several times... the first was in December, I think. ShrinkSafe is an Ajax-enabled (Dojo-powered) web GUI that lets you bundle any number of JavaScript files into one monolith. You can drag the files around to put them in the right order. ShrinkSafe not only merges them, it does the compressor thing on them as well. Compressor itself is based on the Mozilla Rhino javascript engine, probably the best one available. ShrinkSafe also comes as a download for local processing.
