Raudus vs ExtPascal: Delphi web developement alternatives that use ExtJS [closed]

Question

Delphi developers has several tools (several alternatives to ASP.NET) for building web applications.

While No.1 framework is Intraweb, there is a lot of interest around ExtJS, that has 2 incarnations: 1) the opensource ExtPascal 2) the closedsource Raudus

Now the products are different, Raudus never supports the latest ExtJS version (while ExtPascal does because as far as I read it "almost automatically updates itself to the latest ExJS version"), Raudus "seems" much RAD (much similar to Intraweb from the RAD point of view).

Anyway why chose one or the other?

Why Raudus (since it is free) cannot become Open Source? Or does Raudus use ExtPascal behind the scenes?

Comment: uniGUI seems at first sight to combine the good part of Raudus (the RAD part) and ExtPascal (being based on extPascal).

Answer 1

Talking about Raudus, I'd be careful! You can download it for free, indeed. I was about to start using it when I realized there's no single word on its usage license. There's no license in fact, or I was unable to find it under "standard" locations (website? no. installer? no. README / LICENSE file? no.) Thus I'd be careful with using library which doesn't specify it's license. Especially if you're about to start some project which will use it intensely - just imagine what happens when it comes out that you need to pay big amount of money for using it ...

Answer 2

Why use any of them? RAD in the form of Intraweb and tools like it, is not appropriate for web programing. It doens't separate the GUI from bussines logic well. In other words there is no true MVC approach there. Maybe ExtPascal is different here, but the point is elsewhere.

ExtJS is a very well written RAI JS library. It feels almost like putting blocks of code together in a very object oriented way. You can easily build whole GUI with ExtJS without any backend support. This way your whole GUI is in javascript files and no backend is needed. Backend only processes the ajax call and provides data / processes data. This way you have a clear separation of concerns.

This can be easily done without any frameworks. Yes framework would come in handy but it would have to be done in a ASP.NET MVC or Ruby on Rails way. No RAD and no visual designers. New web developers often make those mistakes. But if you program for the web long enough you come to appreciate the separation of GUI and logic and the simplicity of HTML. Web programming is different from desktop programming at least to a degree.

To answer your question. From what I have seen, I like ExtPascal better. It seems a purer web development tool than Raudus. But I admit I have only seen both from the surface and from demo videos, so I cannot judge, only speculate :)
