As far as I understand, you have to write code targeting nodejs, ie, use node-backbone installed in /usr/lib/nodejs (I don't know if that binary package already exist, else you need to create it).

import Backbone from backbone

Webpack will use nodejs dependency resolution and bundle everything into an output file which you can serve to browser.

But this is nothing specific to Debian and you might get a better answer searching for node+backbone. Or in general developing front end in JavaScript. You can also refer to gitlab package and see how it uses webpack.

Since node version in Debian does not support es6 imports yet (it is planned for nodejs 10), you have to use node-babel-loader as well. Check node-d3-zoom for an example.

BTW rollup is also available in Debian now, so you have a choice of rollup or webpack.
