Automated triage (openclaw monitor):

Diagnosis

Current state: No bundle size monitoring or optimization exists. Frontend uses Vite (not webpack), making webpack-bundle-analyzer irrelevant. No automated size tracking, code splitting, lazy loading, tree-shaking configuration, or asset optimization pipeline is implemented.

Possible fix

Frontend (Vite):
- Add vite-plugin-bundle-analyzer or rollup-plugin-visualizer to frontend/vite.config.ts
- Configure buildrollupOptions.output.manualChunks for code splitting
- Add vite-imagetools for image optimization
- Set bundle size limits in CI using size-limit or custom script
Backend:
- Add madge for dependency analysis in backend/package.json
- Create backend/scripts/bundle-analysis.js to track backend bundle size
CI/CD:
- Add GitHub Actions workflow using npm run build -- --analyze and upload artifacts
- Implement performance regression detection comparing bundle sizes across builds
- Add size limits enforcement in frontend/package.json with size-limit

Notes / Questions

Should this be one large PR or multiple focused PRs (monitoring → code splitting → tree-shaking)?
What are the target bundle size budgets for frontend/backend?
Are there specific pages/components causing current bloat that should be prioritized?
Preferred tooling: vite-plugin-bundle-analyzer or rollup-plugin-visualizer?
Should asset optimization include CDN integration or is local optimization sufficient?
