How do I configure webpack to run bootstrap and sass?
<p>I am not great at webpack. I have not really 'learned it', I have a template/boilerplate I pull from a repo I made that gives me an environment to build in React. I am struggling to add bootstrap functionality to my projects because I am not great with webpack and understanding how loaders etc. work. Can someone give me a hand? And maybe a simple explanation about webpack loaders? (It is on my list to learn it, but just not a priority).</p>

<p>I get strange errors like: </p>

<p>ERROR in ./~/bootstrap-sass/assets/fonts/bootstrap/glyphicons-halflings-regular.woff2</p>

<p>Here is my webpack.config.js</p>

<pre><code>var webpack = require('webpack');
var path = require('path');


var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

var config = {
  entry: APP_DIR + '/index.jsx',
  output: {
    path: BUILD_DIR,
    filename: 'bundle.js'
  },
  module : {
    loaders : [
      {
        test : /\.jsx?/,
        include : APP_DIR,
        loader : 'babel'
      },
      {
        test: /\.scss$/,
        loaders: ["style", "css", "sass"]
      }
    ]
  }
};

module.exports = config;
