Analyzes and optimizes JavaScript bundle sizes to improve web application performance and loading speeds.
The Bundle Analyzer skill empowers developers to diagnose and reduce JavaScript bundle bloat across modern build systems including Webpack, Vite, Rollup, and Next.js. It automates the process of installing analysis tools, identifying heavy dependencies like Moment.js or Lodash, detecting duplicate packages, and implementing advanced optimization strategies such as route-based code splitting and tree shaking. By providing actionable insights and automated configurations, it helps engineering teams maintain high performance and fast 'Time to Interactive' for their web applications.
