Workflow to update JupyterLab dependencies automatically

[itsmevichu]

Issue- #7271

Description:
This workflow can be used to update all the jupyterlab dependecies to the latest release. This can also be manually triggered, which takes the JupyterLab version as an input.

Things to re-visit:

• Github secrets, user, email - to create branch and raise PR.
• Executing "yarn install" post dependency updates results in a substantial amount of modifications, with over 15,000 additions and 15,000 deletions. - Done
• Scheduling time for cron job.

The created PR looks like - Sample pull-request

Feel free to adapt the workflow based on your requirements.

Thanks @itsmevichu for looking into this!

Executing "yarn install" post dependency updates results in a substantial amount of modifications, with over 15,000 additions and 15,000 deletions.

Maybe it's because it's using the default yarn (version 1), while the repo here uses yarn 3 via jlpm. So we would probably need to install jupyterlab and use jlpm.

Thanks @itsmevichu.

Looks like this needs a lint pass.

[itsmevichu]

@jtpio The lint check is failing because of the coverage for the scripts. Is it possible for us to exclude the "scripts" folder from coverage checks?

[itsmevichu]

@jtpio I am fetching the latest versions of the lab dependencies from the below URL - https://raw.githubusercontent.com/jupyterlab/jupyterlab/v4.1.4/jupyterlab/staging/package.json.

The package "@jupyterlab/testutils" is not present in the above package.json. As a result, only that specific package won't get updated by this workflow.

Yes I think so. An alternative could be to write the scripts in TypeScript and put them alongside other scripts here: https://github.com/jupyter/notebook/tree/main/buildutils/src

Right it's fine, we only need to update the packages used here in the notebook repo.

@jtpio I have converted the scripts to typescript and included them in the buildutils.
