Webpack Bundle Analyzer

Webpack Bundle Analyzer is a crucial development tool for visualizing the contents of Webpack output bundles as an interactive, zoomable treemap. It helps developers identify what modules contribute most to bundle size, discover unintentionally included dependencies, and optimize the overall build output. The current stable version, 5.3.0, leverages modern ECMA features and continues to be actively maintained with a regular cadence of minor and patch releases. A key differentiator is its ability to parse minified bundles and display their real, gzipped, Brotli, or Zstandard sizes, providing accurate insights into production build sizes. It functions both as a Webpack plugin and a standalone CLI utility.
