Google Web Toolkit VS Quartz

But there are frameworks like GWT or Vaadin for Java, but none of them really took off afaik, I've never seen a job posting with either of these.

FYI, in Java there's this old framework called GWT (Google Web Toolkit) which I use daily at my job. It provides a Java frontend solution which compiles Java to Javascript. (absolutely cursed)

I have not much experience with React and other frontend techs, last time I did something in that space I used GWT... (to be honest, I choose flutter because I wanted to avoid touching JS).

The JavaScript library for the project (not on GitHub) is built with the GWT (http://www.gwtproject.org/) toolkit.

Transpiled languages were nothing new to the web dev community. Let’s see - we had CoffeeScript, Flow, Elm, GWT counts? sure why not, and of course TS (and probably more I’ve neglected). So we must ask ourselves why TS won, right? Well, at least I did.

You might want to try GWT (http://www.gwtproject.org) but it's class library is a bit different than usual java.

In java we have found Quartz( Quartz) , Job Runr(Jobrunr) and db-scheduler(db-scheduler) and need to evaluate these for our use case.

Im mit sit what you mean by "not supported", you sure can run MongoDB on Kubernetes. Maybe I'm way off, are you saying that you can't use Quartz (this one: http://www.quartz-scheduler.org/ ?) because it doesn't natively allow you to load from MongoDB and.therefor you can't use it?

Uh this class is even worse, SDF is not a thread safe date formatter, so it never should be `final static`. `releaseDate` and `new Date()` will be ignorant of summer/winter time changes. For such scheduling one should use Quartz https://www.quartz-scheduler.org/

Long time I used http://www.quartz-scheduler.org which worked nicely, I wonder why Scala does not seem to have something standard for this.

If you end up needing to build one. Check out this long running and well respective java project for ideas: https://github.com/quartz-scheduler/quartz
