I am working on a complex and demanding Angular 2 project for marketing
analytics, and I can tell that with Typescript the development process is
First we need to understand that the Angular project came from the GWT
project. The Google devs realized at that time that they could speed up the
was not something that they could do in the past because the web platform
was not evolved to support complex frontend applications. Now they can
leverage all the js tools, like npm and typescript, web components, etc. So
Google put a lot of workforce in Angular. Now they are dropping GWT
applications like Google analytics in favor of Angular.
The next thing they are planning is Angular Universal, they already have
versions for PHP and .Net Core and a version for Java will be available
Angular server side will enable the pre rendering of pages in the server
and the client router will communicate with the server side router enabling
a faster startup time.
I am using wicket by 4 years now. Indeed components based apps are a good
choice to go. Maybe Wicket should evolve with the web components
specification. In wicket the view (html) is logic less. But this is the
wicket approach. With Angular you put all the view logic in html using the
crazy Angular attributes and components tags. This can be messy but it
greatly speeds up things, as you also don't have to follow an hierarchy
which is required by Wicket. And I know this is a Wicket solution for the
view, and can enabled better testing of components.
I believe that the browser it self became a real platform for applications.
Would be nice to have a material design implemented also in Wicket, like
the React version,
there is also Angular 1
and Angular 2
And some investigation in the reactive streams program model. I think this
can be applied to many aspects of component hierarchy and models. In
Angular 2 supports rxjs for form validation and many other things.
Wicket is a very good framework letting you choose between stateless or
statefull or both! You can't use just Angular, you also need a server
counterpart and for this wicket is a good choice because it is simple and
intuitive to maintain, but if you need performance that the servlet can't
deliver. You need to go for Netty/Akka based frameworks.
