Webpack File Preprocessor Plugin

A lightweight yet generic webpack plugin for pre-processing assets before emitting.

Installation

# Using npm
$ npm install webpack-file-preprocessor-plugin --save-dev

# Using Yarn
$ yarn add webpack-file-preprocessor-plugin --dev

Usage

This example demonstrates how to use this plugin to minify the html assets loaded using file-loader.

const WebpackFilePreprocessorPlugin = require('webpack-file-preprocessor-plugin');
const minifyHtml = require('html-minifier').minify;

module.exports = {
  entry: {
    app: './index.js'
  },
  output: {
    path: './public/dist',
    publicPath: '/dist/',
    filename: '[name].bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.html$/,
        use: {
          loader: 'file-loader',
          options: {
            name: 'tmpl/[hash].html'
          }
        }
      }
    ]
  },
  plugins: [
    new WebpackFilePreprocessorPlugin({
      // Prints processed assets if set to true (default: false)
      debug: true,
      // RegExp pattern to filter assets for pre-processing.
      pattern: /\.html$/,
      // Do your processing in this process function.
      process: source => minifyHtml(source.toString())
    })
  ]
};

Examples
