- Generates Lots of Javascript code. Code splitting solve this problems, but still it generates double(or even more) JS code than that of pure JS app.

Are you basing this on a Hello World example? GWT emulates JDK and so sets up a lot of operational infrastructure upfront. Do you have any specifics on whether all additionally written functionality linearly adds x2 or more JS code? When it comes to comparing applications with scores of screens and hundreds of function points, how do sizes stuck up?

 

- You write code in Java, but you also consider(or Think) how the Javascript will be generated.

You don't need to think much about JS generated from your Java code, but you do have to consider an app in its environment, the browser. In other words, GWT lets you use the Java toolchain but doesn't relieve you from familiarity with HTTP, HTML, CSS, JavaScript and browser behavior.

 

- As far as I know, no new product development uses GWT, lots of company still using it because they can't migrate easily.

 

What about Google Sheets or Inbox, Google's next generation email app? Both started relatively recently and are long term projects. Surely Google leads by example here?

In my opinion, the main problem of GWT is that you are irrelevant for crawlers, and this is a serious commercial drawback, despite I love GWT

Isn't that the case for any webpage generated entirely through JavaScript? (whether that JS has been hand-written, generated from Java code through GWT, or from CoffeeScript, TypeScript, Scala, Closure, you name it)

(and specifically, this applies to AngularJS too, as we're in a "GWT vs AngularJS" thread)

 

If GWT would be able to generate the plain HTML it would beat any pure JS library

Something like http://dev.arcbees.com/gwtp/advanced/crawler-support.html ? (which I don't think is limited to applications using GWTP btw)

See also https://prerender.io/ (independent from the client-side technology, whether GWT, AngularJS, etc.)

But as Vassilis said, Google and Bing execute JS (to some extent) so at least there you're covered without additional work. Things are likely to be different with Baidu and DuckDuckGo (to name a few)
