Bug#934258: Experimentations on packaging jupyterlab

[Julien Puydt <julien.puydt@gmail.com>]

Hi,

I tried my hand at experimental packaging for jupyterlab.

For the Python part, it lacks nbclassic, it's ITP bug #1000667, this
will be done in no time.

The JavaScript part is another story entirely. I made experiments
compiling by hand a few of the packages in packages/.

Here is how you can get as far as me: you need a trick and a patch,
both at the end of this mail. [And of course the relevant node-*
packages!]

Apply the trick in the coreutils, services and statedb directories.

That will allow you to compile, in that order:  coreutils, statedb,
nbformat, settingregistry, observables, services, translation,
rendermime-interfaces, mathjax2, metapackage and pdf-extension.

For the rest, ui-components is as far as I can tell the main blocker ;
it wants typestyle, which in turn wants csstype and freestyle. Perhaps
those are easy, but I don't know yet.

Cheers,

J.Puydt

PS:
The trick is to do this in the relevant packages/ directory:
  mkdir -p node_modules/@types
  ln -s /usr/share/nodejs/@types/node node_modules/@types/

The patch is:
diff --git a/tsconfigbase.json b/tsconfigbase.json
