webpack compression not compressing
<p>I'm using the 'compression-webpack-plugin'.  I get no errors when I run webpack.  However, none of my files are compressed.  Is there something obviously misconfigured here?  Here is my webpack.config.js file. </p>

<pre><code>      var path = require('path');
      var CompressionPlugin = require('compression-webpack-plugin');

        module.exports = {

        entry: path.resolve(__dirname, 'src') + '/app/app.js',
        output: {
            path: path.resolve(__dirname, 'dist') + '/app',
            filename: 'bundle.js',
            publicPath: '/app/'
        },
        module: {
            loaders: [
                {
                    test: /\.js$/,
                    include: path.resolve(__dirname, 'src'),
                    loader: 'babel-loader',
                    query: {
                        presets: ['react', 'es2015']
                    }
                },
                {
                    test: /\.css$/,
                    loader: 'style-loader!css-loader'
                },
                {
                    test: /\.(jpe?g|png|gif|svg)$/i,
                    loader: 'file-loader'
                }
            ],
            plugins: [
                new CompressionPlugin({
                    asset: "[path].gz[query]",
                    algorithm: "gzip",
                    test: /\.js$|\.css$|\.html$/,
                    threshold: 10240,
                    minRatio: 0.8
                })
            ]
        }
        };
