Rails spinoffs - Feb 2008 - could protorype load like scriptaculous? with modules

Hi guys,
I was thinking - wouldn''t it be great to have modules for prototype,
to load separately? Like we have with scriptaculous -
src="scriptaculous.js?load=effects,dragdrop". And that would make it
more lightweight.

Do you think a considerable advantage could be achieved in this way?
Just wondering...

Obviously more requests are bad. But the bigger issue is having a
fleshed out dependency tree for all the objects in the library. That
way if all we need is Element we can easily clip out the Ajax
functionality without having to deal with "object is null". Something
in line with what ExtJS has: http://extjs.com/download/build

I''m starting work on a mobile development platform and I''d
love to use
portions of Prototype. There''s no way I can include the whole thing.

No to scriptaculous''s loading system.
Yes to a custom Prototype build.

Is there something like that floating around?

You could check out the source (http://svn.rubyonrails.org/rails/
spinoffs/prototype/trunk) and edit src/prototype.js. It uses an erb-
like syntax to load the the other modules in src (ajax, array, form,
event, etc.) Remove the ones you don''t need, run "rake dist"
from the
root, run the tests in test/unit and test/functional, make sure
everything you need works, and what you''ve got in dist/prototype.js is
a scaled down version.

You could edit the individual modules to get more granular, but it
might get you closer.

Good call. That''s a looks like a really simple solution.

Hey Shakakai,

Please tell us how effective the methods that you give a try are -
like how much overweight in KB you got rid of..
Thanks

has anyone checked out open rico <http://openrico.org/>?
its built on prototype and it has a module loading mechanism
different than scriptaculous.  so what you do on a given page
is load rico.js, then you have access to the module loader,
which is used simply, by
Rico.loadModule(''moduleName'');
which you can pass multiple parameters or call multiple times.
then there is a sister method, Rico.onLoad(), which will fire once
all the modules loaded by loadModule are available in the dom.
it also has a list of module dependencies akin to what
Shakakai was talking about (abbreviated here)
  moduleDependencies : {
    Accordion  :
[''ricoBehaviors.js'',''ricoEffects.js'',''ricoComponents.js''],
    Color      : [''ricoColor.js''],
    Corner     : [''ricoStyles.js''],
    DragAndDrop: [''ricoDragDrop.js''],

one reason i like it is you can load w/e you like on the initial page;
then later on, if you need some additional functionality, you can just
call Rico.loadModule() again.  it doesnt play nice w/ scriptaculous
tho :(  i have to end up loading some files directly by using <script>
tags sent by the server when using them in tandem.
