j2cl VS j2clmavenplugin

There are many open source projects like, https://github.com/google/j2cl/tree/master/samples/wasm

This was a grand stroll down memory lane; having hacked Java since JDK 1.0, I've seen a lot of improvement.

An idle thought: he favors server-side rendering whereas the javascripts seem to favor client-side rendering. Along the way doing servlets, there came to be "view first" rendering, where you use serverside to paint a minimal page which, itself, uses ajax calls to fill in the blanks. I used that a lot.

It's true also that I migrated from servlets to node. But, in all of this, clojurescript erupted on the scene. And, for me, that's where the piece gets interesting: he introduces us to a java to clojurescript transpiler and tells us it was used to craft the google app suite. Now it's time to go play [1]

So it looks like we have pretty much everything except for the most important part: three.js that we can use from Java. And it’s a little bit of a complex part. To interop with JavaScript we should use J2CL JsInterop API, but there is a little problem: Closure Compiler must be able to recognize types of (most of the) three.js objects. Here we have two options:

You mean https://github.com/google/j2cl ? You understand though that these are trying to solve multiplatform in very different ways. I don't think this approach has a bright future.

Initially J2CL was developed to be used in the Bazel environment. After several years of hard work the community, led by Colin Alworth, released the first public J2CL version for Maven – J2CL Maven plugin.

In the previous article I described how to create and run a simple Java application in a web browser using j2cl-maven-plugin, so if you aren’t familiar with J2CL or Google Closure Compiler I’d recommend taking a look at that article first.

Google loves Bazel (yeah, a monorepo, reproducible and stable builds and so on), we usually use Maven or Gradle for our projects. Luckily, we can try j2cl-maven-plugin that is developed by Colin Alworth from Vertispan, but for now let’s try the Bazel way.
