[Pkg-javascript-devel] Bug#892227: node-backbone: dependencies fail to resolve when jQuery not installed

[Ben Finney]

Package: node-backbone
Version: 1.3.3~dfsg-3
Severity: normal

The dependencies for ‘node-backbone’ do not allow a Backbone
application to be built with Webpack.

=====
$ dpkg --list webpack
[…]
ii  webpack        3.5.6-1      all          Packs CommonJs/AMD modules for the browser

$ webpack --version
3.5.6

$ cat ./webpack.config.js
"use strict";
const path = require('path');
module.exports = {
    entry: './source/foo.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'app.js',
    },
    resolve: {
        modules: ['/usr/lib/nodejs', '.'],
    },
    resolveLoader: {
        modules: ['/usr/lib/nodejs'],
    },
};

$ cat ./source/foo.js
"use strict";
import 'backbone';

$ webpack --config webpack.config.js
Hash: a9597112585b9ca5fb40
Version: webpack 3.5.6
Time: 209ms

ERROR in /usr/share/javascript/backbone/backbone.js
Module not found: Error: Can't resolve 'jquery' in '/usr/share/javascript/backbone'

 @ ./source/foo.js
=====

So the Debian package dependencies are all satisfied, but these are
not sufficient for Webpack to resolve the Backbone dependencies.
