3. Analyzing Bundles

Several tools can help analyze bundle composition, including:

1. Webpack Bundle Analyzer
2. Source Map Explorer
3. Rollup Visualizer

Using Webpack Bundle Analyzer

        // Install the plugin
        npm install --save-dev webpack-bundle-analyzer

        // In your webpack.config.js
        const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

        module.exports = {
            // ... other configurations
            plugins: [
                new BundleAnalyzerPlugin()
            ]
        };
        

To run the analyzer, simply build your project, and a report will be generated, usually accessible at http://localhost:8888.
