Getting Started

Installation

npm i -D replace-asset-name-webpack-plugin
# or
yarn add replace-asset-name-webpack-plugin --dev

Usage

// webpack.config.js
const ReplaceAssetNamePlugin = require('replace-asset-name-webpack-plugin');

module.exports = {
  mode: 'production',
  entry: {
    main: 'src/index.js',
    app: 'src/app.js',
  },
  output: {
    filename: 'js/[name]-[contenthash].js',
  },
  plugins: [
    new ReplaceAssetNamePlugin({
      asset: /main(-.*)?.js$/,
      rules: [
        {
          search: '{APP_ENTRY_REF}',
          replace: /app(-.*)?.js$/,
        },
      ],
    }),
  ],
};

This will replace the occurrence of {APP_ENTRY_REF} in main.js with the output chunk name of the app entry.

In development mode. If you use contenthash for testing. Make sure to enable realContentHash so that chunk names will be updated after replace. This is enabled by default in production mode.
