text-replace-html-webpack-plugin

This package is intended to be used along with html-webpack-plugin. It can be used to replace text in the html file created by the html-webpack-plugin during the webpack build process. Works only wth webpack@^4

Might be used to import gzipped files (eg. bundle.js.gz) instead of .js (bundle.js) in the index.html generated by HtmlWebpackPlugin.

Installation

Install with npm:

npm install --save-dev text-replace-html-webpack-plugin

Basic Usage

Add plugin to webpack config plugins. And pass the replacementArray.

const HtmlWebPackPlugin = require("html-webpack-plugin");
var CompressionPlugin = require('compression-webpack-plugin');
const TextReplaceHtmlWebpackPlugin = require('text-replace-html-webpack-plugin');
const path = require('path');

const htmlWebpackPlugin = new HtmlWebPackPlugin({
  template: path.resolve(__dirname, 'index.html'),
  filename: "index.html"
});

module.exports = {

    mode : 'production',

    output: {
        path: path.resolve(__dirname, 'output'),
        filename: '[name].js'
    },

  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      },
    ]
  },
  plugins: [
    htmlWebpackPlugin,
    new CompressionPlugin({
        filename: "[path].gz[query]",
        algorithm: "gzip",
        test: /\.js$|\.css$|\.html$/
        }

            replace : 'xyz'
        },
        {
            //Will give warning, not error. (As error would have stopped the webpack build)
            regex : /js/ig,
            searchString : 'def',
            replace : (match) => match + '.gz'

        {
            //Will give warning, not error. (As error would have stopped the webpack build)
            searchString : '/index/ig',
