If you’re a developer who uses Webpack for bundling your assets, you might have encountered the issue of unwanted empty JavaScript files being generated alongside your styles. This can be a nuisance, especially if you aim for a clean output directory. Fortunately, the Webpack Remove Empty Scripts plugin comes to the rescue! In this blog, we will unravel how to install and use this plugin to streamline your development workflow.

Why Empty JavaScript Files Occur

Webpack generates a JavaScript file for each resource defined in your entry options. Let’s consider an analogy: think of Webpack as a cook preparing a meal. If you only order a salad (CSS styles), the cook might still prepare an empty bowl for a soup (JavaScript), even though you did not order it. The Remove Empty Scripts plugin helps ensure that only what you ordered gets served!

Installing the Plugin

To install the Webpack Remove Empty Scripts plugin, open your terminal and run the following command:

npm install webpack-remove-empty-scripts --save-dev

Usage with Mini CSS Extract Plugin

To use the Remove Empty Scripts plugin in your Webpack configuration alongside the Mini CSS Extract Plugin, update your webpack.config.js file as follows:

const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const RemoveEmptyScriptsPlugin = require('webpack-remove-empty-scripts');

module.exports = {
    entry: {
        main: './app/main.js',
        styles: ['./common/styles.css', './app/styles.css'],
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: [
                    MiniCssExtractPlugin.loader,
                    'css-loader',
                ],
            },
        ],
    },
    plugins: [
        new RemoveEmptyScriptsPlugin(),
        new MiniCssExtractPlugin({
            filename: '[name].[chunkhash:8].css',
        }),
    ],
};

Additional Features: Using with HTML Bundler
