How to modify Webpack config to load modules from folder name

Question

I'd like to load modules using just a folder name, without specifying file name in that specific folder. Like it's done here in react-starter-kit:

I imagine that this is needed to be done in Webpack configuration, but I cannot wrap my head around that yet (I'm fresh to javascript).

My app is structured this way atm and I have to reference both folder and file name in order to import it.

That's my current webpack.config.js:

const webpack = require('webpack');
const path = require('path');
const autoprefixer = require('autoprefixer');
const htmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  devtool: '#cheap-module-eval-source-map',
  entry: [
    'webpack-hot-middleware/client',
    'tether',
    'font-awesome-loader',
    'bootstrap-loader',
    './app/App',
  ],
  output: {
    path: path.join(__dirname, 'public'),
    filename: 'app.js',
    publicPath: '/',
  },
  resolve: {
    extensions: ['', '.js', '.jsx']
  },
  module: {
    loaders: [{
      test: /\.jsx?$/,
      loader: 'babel-loader',
      exclude: /node_modules/,
      query: {
        presets: ['es2015', 'react', 'stage-0']
      }
    }, {
      test: /\.css$/,
      loaders: [
        'style',
        'css?modules&importLoaders=1&localIdentName=[name]__[local]__[hash:base64:5]',
        'postcss'
      ]
    }, {
      test: /\.scss$/,
      loaders: [
        'style',
        'css?modules&importLoaders=2&localIdentName=[name]__[local]__[hash:base64:5]',
        'postcss',
        'sass'
      ]
    }, {
      test: /\.woff2?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
      loader: "url?limit=10000"
    }, {
      test: /\.(ttf|eot|svg)(\?[\s\S]+)?$/,
      loader: 'file'
    }]
  },
  postcss: [autoprefixer],
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new htmlWebpackPlugin({
      title: 'MoiApp'
    }),
    new webpack.ProvidePlugin({
      "window.Tether": "tether"
    })
  ]
};

However I could not find anything useful on Google. Perhaps I'm making my query not correct enough. Please advice on how to achieve that.

There are different ways to achieve this. Without using some special plugins, you can get this behaviour by putting a pretty small package.json file into the folder with an entry main pointing to the file to be used like it is done in the react starter kit.

{
  "name": "Header",
  "version": "0.0.0",
  "private": true,
  "main": "./Header.js"
}

Another option is to rename the main in every folder to index.js. For details and resolving orders please see the docs at:

https://webpack.github.io/docs/resolving.html

There is also a plugin that helps you avoiding to rename all your files to index.js. I don't have experience with that:

https://www.npmjs.com/package/directory-named-webpack-plugin
