Re: Is it possible to implement a web worker with GWT?

It is, through a linker: http://www.gwtproject.org/doc/latest/DevGuideLinkers.html

It might work with the D8ScriptLinker shipped in GWT (https://github.com/gwtproject/gwt/blob/2.9.0/dev/core/src/com/google/gwt/core/linker/D8ScriptLinker.java); you'll have to declare it in a *.gwt.xml though (define-linker then add-linker).

Or there might be (IIRC, there are) libraries with such a linker specifically for workers.

hi,

I have a GWT web app that I would like to make more reactive by moving some heavy computation code into web workers. This code doesn't need the context of the application to run, I just need to pass it a few input parameters so it should be a good fit for a web worker.

I see how the web app can instantiate web workers using elemental2.dom.Worker.

But as my worker code is in Java, I would like to know if I can use the GWT compiler to generate the worker itself. I expect a js file with a onmessage function as output that I can load from the web app.

Is it possible to do this?
