javascript_include_tag :all?

Thanks,
Gustavo

I don’t think you can.

It’s normally bad practice to use :all anyway. Just include the JS you
need on that particular page.

Thanks,

But in this Scalling Rails tutorial
(http://railslab.newrelic.com/2009/01/22/page-responsiveness), they
recommend to use :all in production systems to reduce page
responsiveness. They said that in production enviroments when you use
“javascript_include_tag :all”, Rails automatically wraps all
javascript files in just one minified file, reducing the total
javascript size and the overhead of multiples GET request.

Apparently you don’t need :all for that. Look at the third syntax.

You don’t usually need all your JS on every page.
