First application working as both J2CL and gwt2 at the same time

[Ahmad Bawaneh]

Hi
I am happy to announce that i was able to build and deploy one of my
applications using both J2CL and gwt2 at the same time.
you can browse both versions here

J2CL : https://dominokit.github.io/dominodoj2cl/index.html

GWT2 : https://dominokit.github.io/dominodo/index.html

for those who wants to to dig in and build the app i have prepared a github
repository, find it here

https://github.com/DominoKit/dominodo

happy J2CLing.. :-)

Cool! :-)

Any numbers about the app sizes, compile and runtime speed (compared between j2cl snd gwt)?

[foal]

Hmm... Looks like GWT wins. Yet.

What i dont understand from the screenshots is why the load of the static
resources should be so different?!

Thanks for posting this.

Not sure if I read this correctly.

Assuming all other being equal (can't really be sure):

GWT: Loading of *.cache.js takes 433ms for 75.8KB - there is also
app.nocache.js 95ms for 3.3KB
J2CL: Loading of app.js takes 490ms for 70.5KB

The difference in timing is of course a network artifact since j2cl has
less code to transmit.

Does j2cl has something equivalent of *.nocache.js. How it is linked? Does
it use an iframe as GWT or is directly loaded in the document window?

I could see a lot of GWT programs breaking if the link model changes...

I agree, if you compare GWT vs J2CL program, then it is fair to switch GWT to single permutation single-script linker before to measure.
And even more fair is to compare all if the compilers [GWT, J2CL, TeaVM], in terms of script size (compressed) and in terms of code performance (not DOM performance).

[Ahmad Bawaneh]

The GWT version already compiled with all properties collapsed

I mean different. Not collapsed, but single perm with sso linker.

[Ahmad Bawaneh]

I was waiting for next weekend to start running some experiments, such notes are really helpful..

[Alina Grynenko]

Thanks a lot. I will try it. One more question: Why j2cl is working with
maven in your application, I thought it works only with bazel?

even though j2cl inside google works with bazel and not maven, since j2cl
was still private there was a work done to make it work with maven, @Colin
built a tool that can run j2cl in a development which uses an old version
of the closure compiler to allow incremental compilation, and now as j2cl
is public the work has already started to make an actual maven plugin for
j2cl, the initial work started based on Colin devmode, you can see the
first version of the maven plugin in dominodo j2cl-maven-plugin, the master
branch is simply running using that simple devmode.. thanks to Colin.
