Re: Which AI do people use for GWT, and how do you use it?

Windsurf is incredible!  Their SWE-1 model didn't perform very well in my experience, but when switching to a different model, wow!  Just tell it the bug, and it figures out the solution, and updates the code for you.  Very impressed.  Thanks for recommending it!

Re: Which AI do people use for GWT, and how do you use it?

Just tried out Claude Sonnet in IntelliJ.  Seems to do a pretty good job, thanks for the tip!

I'm not sure what the advantage of running from the terminal is.  From the IDE, I just select the class I need help with, and ask the AI directly (or with copilot, it works with you in the actual code in the IDE).  I guess if you wanted it to create a whole new project, then running from a terminal would be good.

Re: GWT 2.10.0 Content Security Policy issue for *.nocache.js inline JS

I'm not sure what options 2-5 would have to do with loading the initial fragment, so perhaps this is a series of steps that resolves multiple, different CSP violations?

That is, step 1 should solve the nocache.js trying to append its contents - can you then share the other errors you specifically ran into, and how the fixes were applies, and what errors still remained?

Using a newer version of GWT may also serve you well here - https://github.com/gwtproject/gwt/commit/c6b8b0540b2f86304a0b9764f1499f8142aadf3d is in 2.11 and above, and handles a CSP issue with direct_install. Note that 2.12.2 is latest.

Tried the below options - does not work

1. <add-linker name="direct_install" />

2. MutationObserver

3. Also tried overriding window.__installRunAsyncCode and window.__gwt_getInstallScript to append the nonce value.

4. ScriptInjector value to set the nonce.

5. CrossSiteLinkerFramework to override getJsInstallScript()

This works - But only with No code splitting

Does anyone know how this can be implemented to solve the inline JS issue in GWT.

Re: State of GWT?

Very much our experience. We build commercial apps, and having used GWT for years we know it inside out, so we can build things fast. Yes, it's in maintenance mode, but that also means it's very stable and throws us zero curve balls. We've looked at other frameworks, but all seem to end up with way more code for similar sized solutions - and we're not JS experts, so working in a single Java codebase is way way more comfortable for us. We do divert into JSNI at times to wire in some libs (codemirror, gridstack etc). But we create minimal bindings for just the API calls we need.

 Jens is right, GWT is in maintenance mode. After GWT was handed to the community, all work is done by a few people (like Colin, Jens, Thomas, Ahmad, etc) without getting paid. Not sure, but I think, in case more people starts sponsoring the project (https://opencollective.com/gwt-project) this might change.

If you want create a quick and easy webapp prototype, I recommend using https://github.com/NaluKit/gwt-maven-springboot-archetype to generate a framework based off Spring Boot.

IMHO: GWT's ability to shield you from needing to write JavaScript, is as strong as it has ever been in 2025.

My main pain point with GWT today is actually CSS. CSS is moving pretty fast and GWT is stuck on an old Closure Stylesheets library. Beside that if you really just want to make a throw away prototype I think I would learn a different JS framework for making such prototypes because you simply have to type less code as in GWT with Java. But of course it also depends on the complexity of the prototype as well.

1. I remember GWT was in the process of splitting it into many (J2CL-compatible) submodules, but other than searching Maven Central, I can not find any list of them?

Many of them which are considered completed are available on github at https://github.com/orgs/gwtproject/repositories?language=&q=&sort=&type=all

Colin made a google sheet back in the days at https://docs.google.com/spreadsheets/d/1b1D9fEqRh5lZ8cqMJtYoc_25rfTRvsuJkTtS2vjgi3o/edit?gid=0#gid=0 but it might be outdated. I lost track about the status of not yet completed projects.

 

2. Is there any better way of integrating recent JavaScript libraries other than manually writing my own Elemental2 wrappers? I know Elemental2 bindings are auto-generated from Closure, so I'm hoping that there may be some tools that could generate them at least from TypeScript as well. Not that there were not efforts [5]. My prototype would have to work with maps and although I see that gwt-ol [6] is still maintained, I'm wondering what would be my options if I have to integrate with, for example, Windy API?

Personally I just write JsInterop by hand because most of the time you don't need 100% of the API of a third party JS library. Generated code can also be a bit clunky as seen in elemental2 . Beside the generator you mentioned I don't know any other TS -> JsInterop generator. The one of Google is Closure externs -> JsInterop. 

 

 

3. J2CL seems to remain Google's internal toy, right?

Well you can use it but personally I think you are right, it won't be very popular outside google.
