It's a framework similar to Angular, but written entirely in Java. I have a lot of disappointing experience with GWT widgets (but still use it, as it's still 10 times better than maintaining megabytes of JS code), since it's virtually impossible to create good widget-based abstraction over HTML technoligies. A better approach is a thin layer of abstraction, wich allows easy interaction with underlying nature of HTML.
I could take experience of dukescript <https://dukescript.com/> guys (BTW, TeaVM can be used as dukescript backend) and wrap existing libraries like Angular and Knockout. However, I don't think it is a good approach, since I ask myself: what makes me use Java on front-end? My answer is: it's static typing. When I refactor code, I get errors displayed immediately in Eclipse and have a chance to fix them before I even run application. Consider I wrap angular and pass Java method name to ng-click directive. If later I refactor my Java code and this method got renamed, I won't get any feedback from IDE. And so on. I took many cases and figured out that pure Java-based approach is far superior than JavaScript wrappers, except for complexity. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
