Javascript/CSS asset bundling a prominent feature in Rails 2.0
Actually this stuff even is in Rails Edge ever since February! So in Rails Edge we already can do this:
<%= javascript_include_tag :all, :cache => true %>
<%= stylesheet_link_tag :all, :cache => true %>
Or more flexibly:
<%= stylesheet_link_tag "shop", "cart", "checkout", :cache => "payment" %>
That's cool :)
And it's pretty much the same what my own Bundled Assets plugin does ... besides: my plugin also "compacts" Javascript and CSS by stripping things like comments and whitespace - and it still works on Rails 1.2 of course.
Huh. Wow!
