I might have expressed myself wrong about XStatic packages. But as you 
say as well, to use XStatic packages, we need to most often create them 
and maintain the correct versions we require in Horizon and they don't 
help to packagers either.  I makes sense to use them in Django 
application as they can be included in requirements.txt and we don't 
have to carry them directly in the code. So I am definitely ok to use 
them for Django dependencies we have.

Similar thing is npm and bower doing on the Angular side except for we 
don't have to create these libraries as they already exist. NPM and 
Bower are taking care of including the right versions of js libs our dev 
env and our application needs. They use similar description files as 
requirements.txt in Django.

It makes no sense not to use them and try to include js libraries using 
XStatic packages and listing them in requirements.txt because this way 
we don't know which version of js lib to use etc. NPM and bower are 
doing this for us.

In both approaches dependencies need to have packages in the end 
regadles of being it XStatic package or js library or Angular module.

It is about using the right tools for the job.


I see relation between Nodejs and js libs/tools and Angular app defining 
it's dependencies using NPM and Bower quite similar as Ruby, Rubygems 
and Rails application defining it's dependencies in Gemfile.lock. 
Rubygems are being packaged in distros, so why shouldn't node packages?
