Are you tired of generating extra JavaScript files when you only have CSS entries in your webpack builds? Then the webpack-fix-style-only-entries plugin could be the solution you are looking for! This small yet effective plugin allows you to manage style-only entries without the hassle of extra JS files.

Understanding the Problem

Imagine you are putting together a fashion show. Each outfit (your CSS files) needs to shine on its own without unnecessary fluff (the extra JS files that get generated). Just like how a fashion designer would want to showcase each outfit without distractions, you want your CSS styles to be processed without generating an extra JS file.

How It Works

The webpack-fix-style-only-entries plugin works by scanning through your chunks of CSS entries and removing the associated (but essentially empty) JavaScript files from the compilation. It helps keep your build cleaner and more efficient.

Installation

To get started with this plugin, install it using your package manager of choice:

• npm: npm install -D webpack-fix-style-only-entries
• yarn: yarn add -D webpack-fix-style-only-entries

Configuring Webpack

Once you have installed the plugin, you need to add it to your webpack.config.js file:

const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const FixStyleOnlyEntriesPlugin = require('webpack-fix-style-only-entries');

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 FixStyleOnlyEntriesPlugin(), 
        new MiniCssExtractPlugin({
            filename: '[name].[chunkhash:8].css',
        }),
    ],
};

Options

The plugin offers a few configurable options:

• extensions: Array[string] (default: [less, scss, css, styl, sass]) – Specify file extensions for styles.
• silent: boolean (default: false) – Suppress logs to the console.
• ignore: string or RegExp (default: undefined) – Specify resources to ignore.

Example Configurations

If you want to restrict the plugin to identifying only specific extensions (e.g., foo and bar), you can set it up like this:

new FixStyleOnlyEntriesPlugin({ extensions: ['foo', 'bar'] });

Troubleshooting

Although this plugin is quite straightforward, issues may arise. Here are some troubleshooting ideas:

• If you find that the extra JS files are not being removed, ensure that your file extensions are correctly specified in the extensions option.
• Check your webpack version, as the current package version is not compatible with webpack 5. You can use a fork that is compatible here.
• For any unusual behavior, consider checking the relevant issues on GitHub related to extract-text-webpack-plugin and mini-css-extract-plugin.
