Webpack plugin: replace-hash-in-file-webpack-plugin

This is a webpack plugin that can replace content in file(s) after compilation is done. This is useful when you want to replace content in any kind of files(html, css, js etc) which are not processed by loaders.
Use \[hash to insert the compilation hash into the search and replace when it is a string or a method returning a string i.e. not a regex.
This is heavily based off replace-in-file-webpack-plugin
Install the plugin with npm:
$ npm install replace-hash-in-file-webpack-plugin --save-dev
Basic Usage
Add the plugin to your webpack and config as follows:
const ReplaceHashInFileWebpackPlugin = require('replace-hash-in-file-webpack-plugin');
const webpackConfig = {
    entry: 'index.js',
    output: {
        path: __dirname + '/dist',
        filename: 'index_bundle.js'
    plugins: [
        new ReplaceHashInFileWebpackPlugin([{
            dir: 'dist',
            files: ['index.html', 'main.html'],
            rules: [{
                search: /js\/bundle\.*[a-zA-Z0-9]*\.js/,
                replace: 'js/bundle.[hash].js'
                search: /@title/,
                replace: 'page title!'
        }, {
            dir: 'dist/style',
            test: /\.html$/,
            rules: [{
                search: /version/ig,
                replace: '1.0.0'
                search: '@title',
                replace: function(match){

            dir: 'dist/style',
