Re: Why Don’t You Use Java for Programming the Client-Side Web Apps on Web Browser?

Some tips I could say:
  • GWT is a transpiler / compiler to JavaScript, so the result only runs on Web browser, no server component. Server container or Web server only used for delivering the HTML, JS and CSS. So actually you could just use the result JS from the file system and make a double click on the HTML file to open your web app (JS).
  • The simplest example I build is the Java Calculator from this article: http://bit.ly/WebJavaStory. In this simple Maven example you can see how to run the web app, how to code, transpile and unit test and also to debug the simple calculator all with web browser.
I'm using GWT since 2006 / 2007 and until today I haven't seen any comparable tools which makes your work very productive, especially as a Java developer.

Hope this helps! Have fun!

We also have a Padlet for GWT 😉

I try to collect all the information about GWT / J2CL on one Black Board: https://padlet.com/lofidewanto/gwtintro

There are articles, presentations, groups and other information for a modern GWT / J2CL development...

Hope this helps!

Lofi has some interesting things to look at:  
* GWT Awesome Library List (Gwit a LiLi)
* there is also a boot starter for gwt, but I do not recall the name.

Good starting points are:
*  gwt-maven-archetypes: https://github.com/tbroyer/gwt-maven-archetypes
* There is also are archetype creator from DominoKit
* Nalu project generator: http://www.mvp4g.org/boot-starter-nalu/BootStarterNalu.html (Disclaimer I am the author)

And a good place to ask your questions: https://gitter.im/gwtproject/gwt

Hope that helps.

I am new here, so hello everyone.
I am very interested in this topic. I have gotten tired of the whole javascript ecosystem. I did not know that you could easily have GWT run only on the frontend and used jee/spring/whatever on the backend as you please. I always thought it was a client-server bundle.
Is there a tutorial that shows how it can be done?
How is the compilation speed for code-change/webpage-refresh? I have done scala many years, so I understand how frustrating it can be, even though scala is amazing.

I'm not familiar with React (only Hello World 😉)

Can you integrate React with these GWT React frameworks? So write your components in Java and integrate them back into React JavaScript?

It may be possible in react4j to publish a java component as a react component but not without significant overhead/boilerplate. It is also possible to consume a js react component from within react4j with a little overhead and we built some of our early apps like this. However, react4j's sweet spot is when the majority of the application is written in java.

With gwt-react it is much easier to both consume js components and publish java components ... except for the normal constraints of publishing java to js. My guess is that the sweet spot for gwt-react is for applications that combine js components into a java app but I have never used it in anger.
