💡 What:
Refactored the PDF_TOOLS constant in src/modules/pdf-forge/constants/tools.ts to explicitly import individual lucide-react icons (e.g., FileStack, Scissors) instead of mapping them by string keys. Changed the icon type in PdfToolDef from string to LucideIcon. In src/modules/pdf-forge/components/PdfForgeDashboard.tsx, removed the dynamic wildcard import import * as Icons from 'lucide-react' which bypassed tree-shaking, and updated the mapping to use the directly provided React component.

🎯 Why:
Using import * as Icons combined with dynamic property lookups (like Icons[tool.icon]) defeats Next.js/Webpack tree-shaking mechanisms. This forces the browser to download the entire lucide-react library (~160 KB of extra First Load JS), even though only about 30 icons are actually used on the dashboard. This significantly degraded the initial page load performance of the PDF Forge dashboard.

📊 Impact:
Expected reduction in the First Load JS size for the /pdf route by approximately 150-160 KB uncompressed, resulting in faster parsing, execution, and rendering of the dashboard page.

🔬 Measurement:
You can verify the improvement by running pnpm build before and after this PR and observing the Route (app) First Load JS size for the /pdf route in the Next.js build output. Visually verified that all icons render identically via Playwright.

Summary by CodeRabbit

  • Refactor
    • Enhanced icon handling in the PDF Forge module by transitioning from string-based references to direct component imports. This improves type safety and code consistency across the module.

Refactored `src/modules/pdf-forge/constants/tools.ts` to directly import React components from `lucide-react` and updated the `PdfToolDef` interface. Removed the dynamic wildcard import `import * as Icons from 'lucide-react'` from `PdfForgeDashboard.tsx`. This change allows Next.js/Webpack to effectively tree-shake unused icons, reducing the client-side bundle size.

📝 Walkthrough

Walkthrough

Refactored icon handling in the PDF Forge module by replacing string-based icon names with direct lucide-react icon component imports. Updated the PdfToolDef.icon type from string to LucideIcon, modified tool definitions to reference imported icon components, and simplified icon resolution logic in the dashboard component.

Changes

Cohort / File(s) Summary
Icon Type & Tool Definitions
src/modules/pdf-forge/constants/tools.ts
Changed PdfToolDef.icon type from string to LucideIcon. Added lucide-react icon imports and updated all tool entries to use icon component references (e.g., FileStack) instead of string names. Applied alias ImageIcon for the to-image tool's Image icon.
Icon Resolution
src/modules/pdf-forge/components/PdfForgeDashboard.tsx
Replaced wildcard lucide-react import with named FileText import. Simplified icon component selection to directly use tool.icon with FileText as fallback.
