FAQPage Schema
How do I analyze my Webpack or Vite bundle size to find bloat?▼

To analyze bundle size, the tool parses package.json, lockfile, and build config files to break down bundle composition. It identifies large dependencies and unused code to show exactly why your bundle grew.

What is tree-shaking and how do I enable it for my frontend dependencies?▼

Tree-shaking eliminates unused code from dependencies. The tool analyzes build configuration to identify potential tree-shaking opportunities and recommends specific config tweaks to enable it.

Does this bundle analysis work with Next.js or Rollup configurations?▼

Yes, bundle analysis works with Next.js and Rollup. The tool requires standard build config files like next.config.js or rollup.config.js alongside package.json and a lockfile to generate precise recommendations.

How do I find lighter alternatives for large dependencies in my project?▼

To find lighter alternatives, the tool evaluates your largest dependencies against actual usage. It generates actionable recommendations for lighter replacements to trim unused code and reduce bloating.

What files do I need to run a bundle optimization report?▼

You need package.json, a lockfile, and standard build config files like webpack.config.js or vite.config.js. Providing these files allows the tool to generate precise AI-driven bundle optimization recommendations.
