I'd like to develop a javascript-heavy widget extension for the jupyter notebook. I managed to install the example widget and it seems to be working. However, I can't seem to make changes to the typescript source code take effect. I tested it using multiple console.log instructions, and also verified the source code loaded in the browser is not showing the changes.

I would appreciate some help how to setup a workflow for extension development. So far, the readme is missing the "npm install" (I think, maybe it's not necessary?). I also tried npm scripts watch and build.

Thank you for your time!
