He Guys If you’re like me and never managed to really understand seaside, you should have a look at Cincoms AppeX, which really makes a gréât difference in writing web applications the natural way if that is the bottom line of your concern. 
In AppeX, you only need to know two things, smalltalk and javascript, you write the later directly (with syntax control) in the smalltalk IDE which makes for a real différence. Personally I write on top of jQuery, Bootstrap, Stripe and numerous additional plugins. My only problems remain in really understanding javascript and jquery.

Even though development speed pick's up as soon as you have implemented your basic framework and components I always thought it might be more convenient to use the specialized IDEs for HTML, JS and CSS for the first visualization of your proof of concept.
> Now I stumbled across Polymer and I finally had the impression that one can, just like in Seaside, built small easy to understand components and grow from there. I actually like the separation of JS, HTML and CSS in Polymer as well as the loosely coupling of the application parts via events,.... just like in Smalltalk.

> Unfortunately I was very close to write you anyways that it currently seems to me as if PharoSJ is not really there yet. I understood the concept behind PharoJS but to integrate the needed websocket proxy layer of PharoJS into Polymer is something I still have trouble to wrap my head around.
> I think Noury or Dave will first have to tell me how they would integrate something like jQuery into PharoJS in order to enable me to take what I already have and finish the Polymer parts missing.
> One might be able to use Polymer right now, but the resulting JS code would not be comparable to the one used in the Polymer documentation and that does not really make sense to me. One would implement PharoJS Code that accesses/manipulates an existing polymer object based on http://polymer.github.io/polymer/ <http://polymer.github.io/polymer/> Polymer.Base and not just provide a json specification as a configuration for a Polymer constructor.
> I am not sure yet if PharoJS is the right thing for me. I still feel like writing Amber or Seaside code but this time against a wall of proxy objects (document, window, WebSocket, ... ). I, again, need to know and learn the api of those first class objects and their particular behaviors... 
> But if you would like to implement pure logic, independent from third party libraries then PharoJS is alreay providing a lot to accomplish that.
> The only thing that needs more attention is the layer that takes care of the proxy and web socket live cycles. I have to restart my image too often to have a working JbBridge again...
