Can I replace the kernel.js file with my own?

[ans...@broadinstitute.org]

Hi,

I would like to replace (or modify) this kernel.js file: https://github.com/jupyter/notebook/blob/master/notebook/static/services/kernels/kernel.js

I want to do this because restarting or switching my kernel within a notebook sets up an infinite loop of the websocket trying to connect failing and retrying. I want to modify the kernel.js as a workaround so that it just reloading the page after killing the session and creating a new session. 

 

Is there a way for me to do modify the kernel.js to do that? 

I know that you can define a kernel.js per kernel, but I don't think that will work in my case, as I believe the custom kernel.js runs after the kernel.js linked above, so we'd be stuck there and the custom kernel.js would never run. (please correct me if I'm wrong in that assumption)

Thank you!

The JS files aren't loaded directly, rather they're bundled into a big file called main.min.js. There's information on how to rebuild that here:
http://jupyter-notebook.readthedocs.io/en/stable/contributing.html#setting-up-a-development-environment

If you can see what you need to do, you're free to change any of the code in Jupyter. But if something's going wrong, it might be best to file an issue and try to work out a fix that we can incorporate into the project - that way it's also solved for anyone else with the same problem.
