Trying to migrate to JupyterLab from Jupyter Notebook?

Some time ago I noticed that the Jupyter extensions project was more or less frozen => JupyterLab obviously is trying to shift community attention to npm / nodejs plugins.

Again (like 6-12 months ago) I tried to do this.

This time Lab is more mature:

- Now at version >1;

- Now they have built-in package manager;

- They have some of the most necessary extensions (i.e. git, toc, google drive, etc);

- UI got polished a bit, but window in a window still produces a bit of mental friction. Only the most popular file formats are supported. Text editor inherited the best features, but it is still a bit rudimentary;

- Full screen width by default;

- Some useful things (like codefolding) are now turned on in settings json file;

- Using these extensions is a bit of a chore in edge cases (i.e. some user permission problems / you have to re-build an app each time you add an extensions);

But I could not switch mostly for one reason - this one

- github.com/jupyterlab/jupyterlab/issues/2275#issuecomment-498323475

If you have a Jupyter environment it is very easy to switch. For me, before it was:

# 5.6 because otherwise I have a bug with installing extensions
RUN conda install notebook=5.6

RUN pip install git+https://github.com/ipython-contrib/jupyter_contrib_nbextensions && \
jupyter contrib nbextension install --user

CMD jupyter notebook --port=8888 --ip= --no-browser

And it just became:

RUN conda install -c conda-forge jupyterlab

CMD jupyter lab --port=8888 --ip= --no-browser


Support collapsible hierarchy of sections · Issue #2275 · jupyterlab/jupyterlab

Allow users to toggle open/close sections by clicking on some kind of UI element. This helps with navigating and organizing large notebooks.
