I want to build a Web App with Rails.... What to use for the Client Layer?

Hello, I'm building a web app that I want to have a feel like GMAIL.

I have Rails 3 setup for all the backend, restful type services... But
I want it to be a web app and not a web page. What are some client-
side type frameworks I should be thinking of? not like a JQUERY but
more like a sproutcore? Is there anything type of framework Rails
developers use to have slick Web APps, so clicking links does not
reload the entire page, etc.. etc...

Thanks!

You can build an entirely non-page-reloading site using just Rails with jQuery.

Sproutcore seems very nice, but is overkill for most of my projects.

Greg, GMAIL like not a GMAIL clone, not anything related to an EMAIL
app.. thxs

What do you people think about Netzke ?

Robert Pankowecki

the only thing prebuild that i have seen that do that , no one uses them in the public part of their site, only in the admin section
check a gem called active_scaffold but i think you cant customize it much

What do you people think about Netzke ?

Netzke is ExtJS right? I'm not a big fan as they learning curve is
insane and the bang isn't worth the time.

I agree. And I want my tools to be more generic than that.

I suppose you're not allowed to use Flash/Flex?

For non-Flash, moderately rich UI, I'm pretty happy with some of the
YUI (Yahoo User Interface) widgets and libraries.

You might also consider GWT. If you know that you're building a big
fat (rich) client, it might be worth having a comprehensive IDE with
debugging goodness that GWT offers.
