Bundle size analysis and optimization for Webpack, Vite, and esbuild

Bundle Size Analysis & Optimization

I'll analyze your JavaScript bundle size, identify large dependencies, suggest tree-shaking opportunities, and recommend code splitting strategies.

Supported Build Tools:

  • Webpack (webpack-bundle-analyzer)
  • Vite (rollup-plugin-visualizer)
  • esbuild (esbuild-visualizer)
  • Rollup (rollup-plugin-visualizer)
  • Next.js (@next/bundle-analyzer)

Arguments: $ARGUMENTS - optional: production/development or specific entry point

<think> Bundle optimization requires understanding: - JavaScript bundle composition and size impact - Tree-shaking effectiveness - Code splitting strategies - Lazy loading opportunities - Dependency bloat identification - Framework-specific optimization patterns </think>

Token Optimization

Expected range: 300–2,500 tokens (initial), 200 tokens (cache hit)

Caching: Caches build tool detection in .claude/cache/bundle-analyze/build-tool.json for 7 days. Invalidated when package.json changes.

Early exit: Returns immediately for already-analyzed bundles or if no build output exists.

Patterns used: Grep-before-Read, early exit, Bash for system queries, caching
