Difference between Ext JS and Ext GWT

[Chudomir Delchev]

Hi,

I'm a newbie in the ext toolkits and I'm trying to save some research time :)

My question is - what are the main differences between these two libraries?
I need to develop a small web application with some forms, lists, trees etc.
Is GWT more complex but learning-time wasting?

Thanks in advance for any help.

Best Regards

I would never consider learning time wasted! In fact, i'd say time well spent instead of vegging infront of youtube, etc.

From what i've learned (Thanks Sven and co):

Ext GWT != Ext JS, even if they look the same. What you use depends on what you need to do.

Have a look at the product pages and blog postings on the site..

Ok - my mistake for "learning-wasting" words -
I meant it would be bad to choose the "wrong" library of the two which would take me more time to learn and at the end to produce the same result.
Thanks anyway.

Outline what you need to do, then research each framework and see what would be easier for you to do that in.

Either way, you have a learning curve to overcome.

You should alco consider what you already know. Do you already know java and are planning to write your serverlogic in java?

If so, than Ext GWT could be what you are looking for. With Ext GWT you write your fronted fully in java. You dont have to know javascript.

I agree it you...

So after climbing thouse learning curves, I'll come back here and write what I've found - may be saving time for someone else.

thanks for your reply Sven - I plan to do it by using php on the server site (zend framework actually) and javascript on the client side. So I guess ext JS would be my choice for now

You could also use PHP on the serverside when using Ext GWT.

via quercus (http://www.caucho.com/resin-3.0/quercus/)?
or did you mean something else?

Yes you could, but is there somebody actually doing that? Won't you loose all those nice testing benefits you get when programming both the GUI and the backend in Java?

I assume sven meant writing the GUI in Java and the backend in PHP.

[sven]

No you can have your normal php scripts at the serverside that print out json or xml or whatever, as you would do with normal javascript in the frontend.

i was thinking the same thing.

but that would mean having to both know and maintain a mixed bag of code (java for the frontend, and PHP for the back).

Dont you have to do that also if you use php and javascript? ;)

Yes there are people doing that. It also makes sense to do that. You could have services that you cant change because other apps need them to stay as they are.

Touché :)
