You could easily set it up as a couple different keys if you wanted but I find myself using everything but builder.js on a regular basis (guess i could drop that from my include) because of larger widgets i’ve built so its just easier to pull it all in and let a single client side cache check be performed.

Include this as the source to load only the base and the effects lib.

‘js/scriptaculous.js?effects’

Also they have added url style get variables to specify what is included:

i.e. including:

Will load the base and the effects.js library..

Javascript compression – can be tricky – best bet is to gzip the output from the webserver…

Adding a Javascript compressor, would be a nice touch. One of the things I don’t like about using javascript libraries is that to get what I need using libraries I don’t just use 1 library, but have to load up a couple different libraries, which causes too much overhead.

If I could use take the JS libraries that I need and then load them up through HTML_AJAX, which would compress the js before serving it, that would rock.

Another thing that I’ve wanted for a while is a way to create Javascript dependancies. For example I only need to use one effect out of a library, but instead of loading up the entire library I would use HTML_AJAX to call that effect. HTML_AJAX will then work out what functions are needed for that effect to work, compress the JS and serve it to me. That would rock
