How to set up webpack for Pug, React, and ES6

Question

I’m trying to make a website using React and ES6. I’m using Webpack to transpile my JS using Babel and it works fine. Now I need to know how to write my template in Pug (or HTML for that matter) and add it to the Webpack workflow. I want my build folder to have two files:

1. My bundle.js
2. My index.html file compiled from my index.pug file

An example webpack.config.js file would be helpful but what I really would like is just the general idea of how to do this.

Thanks!

There are few webpack plugins you need to install first to use pug template with webpack.

1. htmlwebpack plugin
2. pug-loader

With htmlwebpack plugin you can specify your pug template file

new HtmlWebpackPlugin({
      template : './index.pug',
      inject   : true
})

pug template file will be loaded by pug-loader.

    {
        test: /\.pug$/,
        include: path.join(__dirname, 'src'),
        loaders: [ 'pug-loader' ]
    },

A sample webpack config file can be like below -

const path              = require('path');
const webpack           = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

const isTest = process.env.NODE_ENV === 'test'

module.exports = {

  devtool: 'eval-source-map',

  entry: {
      app: [
          'webpack-hot-middleware/client',
          './src/app.jsx'
      ]
  },
  output: {
    path       : path.join(__dirname, 'public'),
    pathinfo   : true,
    filename   : 'bundle.js',
    publicPath : '/'
  },

  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new ExtractTextPlugin("style.css", { allChunks:false }),
    isTest ? undefined : new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
    }),
    new HtmlWebpackPlugin({
          template : './index.pug',
          inject   : true
    })
  ].filter(p => !!p),

  resolve: {
    extensions: ['', '.json', '.js', '.jsx']
  },

  module: {
    loaders: [
        {
            test    : /\.jsx?$/,
            loader  : 'babel',
            exclude : /node_modules/,
            include : path.join(__dirname, 'src')
        },
        {
            test    : /\.scss?$/,
            loader  : ExtractTextPlugin.extract("style-loader", "css-loader!autoprefixer-loader!sass-loader"),
            include : path.join(__dirname, 'sass')
        },
        {
            test    : /\.png$/,
            loader  : 'file'
        },
        {
            test    : /\.(ttf|eot|svg|woff(2)?)(\?[a-z0-9]+)?$/,
            loader  : 'file'
        },
        {
            test: /\.pug$/,
            include: path.join(__dirname, 'src'),
            loaders: [ 'pug-loader' ]
        },
        {
            include : /\.json$/,
            loaders : ["json-loader"]
        }
    ]
  }
}
