ExtPascal has serious licensing issues, you can only develop open source projects with it. We wanted to integrate ExtPascal but Sencha demanded royalty payments because you are not allowed to use/distribute Sencha in anyway closed without source. Thus even if you create a web-module and distribute the javascript part Sencha will ask for royalty OR to also open your pascal side code.
I personally really like ExtPascal and I tried hard to negotiate with Sencha for a reasonable royalty but no success. In the end we had to drop ExtPascal and moved on to XUL which has royalty free licensing model.
The problem is not the JavaScript part that you kind of have to distribute with your solution the problem with Sencha is that you also have to open your pascal side code and this is the only reason why such a good solution like ExtPascal is not widely used.
Oh Lord, sad news for me.

Do you know the similar "packages" for web developments, like ExtPascal had?
I mean, extpascal provide "desktop-programming"-like, Is there another package like extpascal had? (we can build web "just" drag and drop the component, e.g. button).
Well, thank you so much for your information, Mr. PlusPlus.
