Not clear what I need to do to get this to work

I've added the following to my setup:

// package.json
    "css-loader": "^0.23.1",
    "file-loader": "^0.8.5",
    "foundation-sites": "^6.2.1",
    "foundation-sites-loader": "^1.0.1",
    "json-loader": "^0.5.4",
    "node-sass": "^3.6.0",
    "sass-loader": "^3.2.0",
    "style-loader": "^0.13.1",
    "transform-loader": "^0.2.3",
    "url-loader": "^0.5.7",
// main.js
require("foundation-sites-loader");

But when I run webpack it doesn't add anything to my output. Here's my webpack.config:

'use strict';
let path = require('path');

module.exports = {
  entry: './app/main.js',
  output: {
    path: path.resolve(__dirname, 'public/build'),
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: /aws-sdk/,
        loaders: [
          'transform?aws-sdk/dist-tools/transform'
        ]
      },
      {
        test: /\.json$/, loaders: ['json']
      },
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader'
      },
    ]
  },
  node: {
    fs: 'empty'
  },
  devtool: 'source-map'
};
