Anywidget for JavaScript kernel

[MRYingLEE]

Now there is a JavaScript kernel for Jupyterlite, https://github.com/jupyter-xeus/xeus-javascript.

For Anywidget is developed in TypeScript, maybe it is easy to be adapted to run in the JavaScript kernel in an even simpler way.

Of course, there should be some backend work. If no one works on it. I will do it.

Thanks,

Want to have a look at what we've done for the Deno kernel? It's another JS/TS Jupyter kernel that we've already implemented adapters for. I bet there is a lot that can be reused if you'd like to try creating such an integration for the kernel you've shared.

• https://docs.deno.com/runtime/manual/tools/jupyter (info on the Deno kernel)

The main issue for non Python kernels (and connecting with the anywidget front end) is that anywidget's JS code must be installed also in the kernel. This happens automatically when you pip install anywidget, but would need to be emulated for different kernels. You can see the install script in deno package that does this.

It is great that AnyWidget can run on Deno now.

I read all contents on https://anywidget.dev/, but I didn't expect you had worked on JavaScript kernel already. It is worth mentioning in the Readme.md.

Thanks.

Good point! I just haven't advertised widely as it is very experimental. I'll get on adding it to the readme.

FYI. xeus-javascript is working to support Anywidget (jupyter-xeus/xeus-javascript#17).
