Cascade Added Large Dependencies - Bundle Bloat

Frontend bundle size increased dramatically after Cascade added new JavaScript dependencies. Page load time increased significantly, negatively impacting user experience and SEO metrics.

Cascade suggested useful libraries without considering bundle size impact or suggesting tree-shaking options.

Error Messages You Might See

Bundle size increased from 200kb to 850kb Load time increased from 2s to 8s Largest bundles detected in analysis
Bundle size increased from 200kb to 850kbLoad time increased from 2s to 8sLargest bundles detected in analysis

Common Causes

  1. Cascade added monolithic library (e.g., lodash) instead of using small utility packages
  2. Added development dependencies to production bundle by mistake
  3. Cascade removed tree-shaking configuration or import optimization
  4. Multiple packages provide similar functionality (polyfills, utilities)

How to Fix It

Analyze bundle with webpack-bundle-analyzer or similar. Identify large dependencies. Consider lighter alternatives (e.g., lodash-es instead of lodash, date-fns instead of moment). Enable tree-shaking in bundler config. Use dynamic imports for code splitting. Lazy load non-critical dependencies.
