Bundle Size Increased After Cursor Refactoring
Your application's bundle size has significantly increased after Cursor refactored the code. Load times are now slow, especially on slower networks and mobile devices.
The refactored code may be importing unused dependencies or breaking code splitting.
Error Messages You Might See
Common Causes
- Large library imported entirely instead of specific functions (lodash vs lodash/map)
- Code splitting disabled during refactoring
- Tree shaking not working due to import structure changes
- New heavy dependencies added without considering alternatives
- Asset inlining or image compression removed
How to Fix It
Analyze bundle: webpack-bundle-analyzer. Import specific functions: import {map} from 'lodash' not import lodash. Enable code splitting: splitChunks in webpack. Check for unused packages: npm ls --depth=0. Use lightweight alternatives (lodash-es vs lodash).

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

How do I measure bundle size?
Use webpack-bundle-analyzer plugin or build tools. Check npm package size with bundlephobia.com. Monitor in CI.
What's code splitting?
Splitting bundle into chunks that load on demand. Routes load when accessed. Dynamic imports: import('module').then().
