I can confirm that the upstream instructions do work to regenerate widgetsnbextension/static/extension.js from https://pypi.python.org/pypi/widgetsnbextension/1.2.6

However we're going to have a hard time recreating it in Debian. I went through this file and saw the "real dependencies". scriptjs seems to not be needed, but the others are.

There are 56 modules (0-55) that webpack concatenates together, they are:

External:
2: underscore
3: backbone 1.3.3
4: jquery
7: jquery-ui
8: commonjs/grunt magic, easy to recreate manually
9-20: bootstrap 3.3.6 (transition, alert, button, carousel, collapse, dropdown, modal, tooltip, popover, scrollspy, tab, affix; all in Debian as v3.3.7)
24: backbone 1.2.0, LOL
25: node-semver
*26: stub file from node-process, "shim for using process in browser"
*38: d3format
*45: html2canvas
52: possibly node-style-loader, not sure
*54: node-css-loader
*55: node-style-loader

*not in Debian

Local, part of juypter-js-widgets / nbwidgetsextension:
0: local code
1: local code
5: local code
6: local code
21-23: -- local code 
27: jupyter-js-widgets's package.json
28-37: local code
39-44: local code
46-48: local code
49: widgetsnbextension's package.json
50, 51: local code
53: local code, minified version of widgets.css

    + 49 hidden modules

There is also ipywidgets.git/jupyter-js-widgets/dist/embed.js which is 74 modules, which I haven't yet analysed. We don't strictly need that for widgetsnbextension; for SageMath we could just omit the jupyter-js-widgets binary package.
