Large web applications

[bkraut]

I'm wandering if anyone has experience how to minimize the load time in very large applications build with extjs? How all js are incuded (are they included on demand or all at the same time? Load time?)

With google search you might try terms: minify, concatenate

and gzip

Also read Tutorial:Building Ext From Source (covers everything except gzip).

Ok. I know all of this. I found also a pearl script that builds all js that are used into a single js.

Also know how to build my own ext.js. My application uses a lot of functionality of standard ext classes. But I'd like to know how to use extjs when you build a system with 5000 predefined classes. How to load them? Even if this is one file and minified it is big.

Is there an option to load classes dynamically - maybe with help of a central class register and Jaxer?

Well, if you know all that, maybe be more specific so someone can help you more specifically.

Maybe you want Ext.ux.Plugin.RemoteComponent

There are also starting to be some experimental steps taken towards implementing an automated on-demand library loading system. JScout is one, I know I have seen at least one other discussed.

Oh, reminds me, I think Doug had some plans to implement something also. Search his extensions?

Great. RemoteComponent fits just perfect.
Thanks for mentioning.
