Webpack: how to make angular auto-detect jQuery and use it as angular.element instead of jqLite?

Got this answer from john-reilly:
The mysterious case of webpack angular and jquery

bob-sponge’s answer is not quite right – the Provide plugin is actually doing a text replacement on modules it processes, so we need to provide window.jQuery (which is what angular is looking for) and not just jQuery.

In your webpack.config.js you need to add
the following entry to your plugins:

new webpack.ProvidePlugin({
    "window.jQuery": "jquery"
}),

This uses the webpack ProvidePlugin and, at the point of
webpackification (© 2016 John Reilly) all references in the code to
window.jQuery will be replaced with a reference to the webpack module
that contains jQuery. So when you look at the bundled file you’ll see
that the code that checks the window object for jQuery has become
this:

jQuery = isUndefined(jqName) ?
  __webpack_provided_window_dot_jQuery : // use jQuery (if present)
    !jqName ? undefined : // use jqLite
    window[jqName]; // use jQuery specified by `ngJq`

That’s right; webpack is providing Angular with jQuery whilst still
not placing a jQuery variable onto the window. Neat huh?
