What is Webpack bundle analyzer?
Webpack Bundle Analyzer is a tool that visualizes the size and composition of webpack bundles using an interactive zoomable treemap. It helps developers identify which modules contribute most to bundle size, detect accidentally included modules, and optimize their webpack builds for better performance. The tool supports analyzing minified bundles and shows various size metrics including gzip and Brotli compression.
Frontend developers and build engineers working with webpack who need to analyze and optimize their application's bundle size for performance improvements.
Developers choose Webpack Bundle Analyzer because it provides an intuitive visual interface for bundle analysis that's more actionable than raw stats, supports multiple compression algorithms, and integrates seamlessly as both a webpack plugin and standalone CLI tool.
