Does webpack not write to disc?

I'm trying to get webpack bundle working with my node.js application, but I cant seem to find the physical webpack bundle. Is there even one? I'm familiar with gulp where it outputs a bundle into a folder you specifically choose, but I cant get it to work with webpack. docs aren't that helpful either

Care to post your Webpack config?

Generally speaking, your Webpack config will specify, at minimum, an 'entry' and an 'output'; it will start with your entry (typically an app.js file), do all the bundling and output the resulting bundle where you tell it via 'output' (usually a file that lives in a 'dist' folder that is then run inside of your index.html to produce your app!).

If you're using hot-reloading, then the bundle is in memory only and that's why it's typical to have a 'dev' webpack config and a 'production' config with only the latter writing to disk.

For example, just a basic config with no hot reloading:

module.exports = {
  entry: __dirname + '/src/js/app.js',
  output: {
    filename: __dirname + '/src/js/app-bundle.js'
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        loader: 'babel',
        exclude: /node_modules/
      }
    ]
  },
  devtool: 'sourcemap'
}

output can take a number of options: https://webpack.github.io/docs/configuration.html

hope that helps!
