bundle-optimizer

Reduce webpack bundle size by analyzing large dependencies, applying tree shaking to eliminate unused code, and implementing code splitting via dynamic imports to decrease initial JavaScript payload and improve page load speed.

Tree shaking optimizes web application bundle size by statically analyzing code to detect and remove unused exports and dead code, ensuring inefficient resource utilization is eliminated from the final build.

Yes, the bundle-optimizer Skill works with Vite code splitting. It provides guidance on implementing dynamic imports and dependency management strategies specifically tailored for Vite to optimize bundle size.

The best way to analyze JavaScript bundle size is using bundle analysis tools to inspect build output. This identifies which third-party libraries and modules contribute most to large bundles, enabling targeted dependency optimization.

Your webpack bundle remains large after code splitting if third-party dependency management is inefficient or tree shaking is misconfigured. Analyze the build to identify heavy libraries and ensure unused code is actively stripped.
