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

Answer 1

After using Raudus it seems that it is not practical for large scale of applications. According to their documentation and I have also sampled, it serializes all client request into single main thread. However it process client request and response generation part in multi-threaded enviornment.

But main thread issue is quite important as it directly impact the response time if one action is taking more time in the main thread, others will keep waiting.

Any suggestions to resolve this issue?

user193655 --> Depending on what you do be carefull with both approaches. I am really a big fan on Delphi or Freepascal/Lazarus - I am not very certain if the approach of bringing 3GL bindings to the Javascript stuff is wise.

MVC - depending on what you do - in PHP you have the Yii Framwork or Prado. Maybe the second has some ideas from .net built in which are very easy to understand by Delphi developers. PRADO is an event driven approach while YII Framework is absolutely cool and unix like.

Answer 3

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 :)

Answer 4

The Raudus developer put up a new blog post in late October and claims, well I'll let you read the snippet for yourself:

"Raudus license is freeware as written in license.txt. You CAN use Raudus in commercial projects. Raudus sources are not available yet."

Answer 5

Raudus:

• Relies upon Delphi, in which:
  • Is verbose;
  • Relies upon Microsoft Windows;
  • High-cost to adapt to or to maintain;
• Quote from raudus.com: "Raudus is freeware. You can freely use Raudus for commercial purposes. Raudus sources are not available yet." — This, to me, will be never a license. On the homepage, simply there is no documentation about Terms of Service or something like that. Hence I won't deal with their services.

Edit: There is a license statement at the bottom of the http://www.raudus.com/ page.

"License

Raudus is freeware. You can freely use Raudus for commercial purposes."
