npm is already in Debian:
https://packages.debian.org/sid/npm

However, just like we can't use CPAN, "pear install", "pip install" and
such when building or installing package, we wont be able to use NPM.
This means every single dependency that isn't in Debian will need to be
packaged.

I have no problem with adding dependencies. That's how things work, for
sure, I just want to make sure it doesn't become hell, with so many
components inter-depending on 100s of them, which would become not
manageable. If we define clear boundaries, then fine! The above seems
reasonable anyway.

Though did you list the dependencies of the above?

Also, if the Horizon project starts using something like NPM (which
again, is already available in Debian, so it has my preference), will we
at least be able to control what version gets in, just like with pip?
Because that's a huge concern for me, and this has been very well and
carefully addressed during the Juno cycle. I would very much appreciate
if the same kind of care was taken again during the Kilo cycle, whatever
path we take. How do I use npm by the way? Any pointer?
