How do I set up parsely with nodejs

Question

For days, I've been working on form validation. I'm trying to validate a form that has multiple steps.

Nodejs, ES6, Express, and PUG are the technologies I'm using. I'm having trouble coming up with something that works. I believe parsley would do the trick for me, but I'm having trouble getting it to work with NodeJS.

In my.js file, I have the following code (where risk-calc is the id of my form):

$('.form-navigation .next').click(function() {
  if ($('#risk-calc').parsley().validate({group: 'block-' + curIndex()}))
    navigateTo(curIndex() + 1);

My console error is '$(...).parsley is not a function.'

I've installed via NPM parselyjs and jquery.

edit.

Attempting to use webpack to add global variables.

Something is still wrong, but how does this look?

plugins: [
    new ExtractTextPlugin('style.css'),
    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery',
      parsley: 'parsleyjs/dist/parsley.js'
    }),
