Move to the jupyter-resource-usage repo

[jtpio]

The lab extensions provided in this repo should eventually be moved to https://github.com/jupyter-server/jupyter-resource-usage.

This will avoid having an external dependency on nbresuse / jupyter-resource-usage.

And using the new distribution system for federated / pre-built extensions in JupyterLab 3.0, it will be easier to have everything installed and working with a single pip install jupyter-resource-usage.

There is on-going work to move the status bar item from core lab to jupyter-resource-usage: jupyter-server/jupyter-resource-usage#69

Regarding the dependency on the topbar plugin, this could be made optional. With https://github.com/jtpio/jupyterlab-topbar staying as-is and providing the token. For example:

• Check jupyterlab-topbar is installed and the ITopBar token is available. If so, add the indicators to the topbar just like now.
• If not available, add the indicators to the top area instead with app.shell(widget, 'top')

This way users will only get the functionality if they ask for it with pip install jupyterlab-topbar.

The issue jupyter-server/jupyter-resource-usage#69 has been merged. Does it mean that jupyter-resource-usage is preferred over jupyterab-system-monitor now?

Does it mean that jupyter-resource-usage is preferred over jupyterab-system-monitor now?

Not yet. For now jupyter-resource-usage only adds the status bar indicator for JupyterLab.

With this issue the idea would be to move the visual top bar indicator to jupyter-resource-usage:

Then when it's done users could do a single pip install jupyter-resource-usage to insall everything at once.

Closing as jupyterlab-system-monitor has now been integrated in jupyter-resource-usage: jupyter-server/jupyter-resource-usage#191
