Note: Upgrading the UI library is not among the CODAP V3 requirements, but I was curious about Claude's assessment. I was not expecting the upgrade to be this expensive, however, and I find Claude's suggestion that switching to another library would be a similar effort to upgrading to ChakraUI v3 fascinating.

Summary

  • Add comprehensive migration plan document for upgrading from Chakra UI v2.8.2 to v3
  • Document current usage: 83 files importing Chakra components, 45+ unique components
  • Analyze major breaking changes and estimate 15-25 developer days of effort
  • Include detailed comparison of alternative UI libraries

Key Findings

Current Usage:

  • 83 files import Chakra UI components
  • Heavy usage of Menu (14 files), Modal, useDisclosure (16 files), Form components
  • 5 custom theme/style files with extensive customization
  • 12 SCSS files with Chakra class overrides

Major Breaking Changes in v3:

  1. Complete theme rewrite - extendThemecreateSystem with new token format
  2. Compound components - Modal→Dialog, Menu.Item, Checkbox.Root patterns
  3. Boolean props - isOpenopen, isDisableddisabled
  4. Icons removed - Must migrate to lucide-react or react-icons
  5. Hooks changed - useDisclosure API changes, color mode hooks removed
  6. No incremental path - v2 and v3 providers conflict

Effort Comparison:

Path Estimated Effort Risk Level Long-term Maintenance
Chakra v3 15-25 days High (incomplete docs, new patterns) Medium (more rewrites possible)
Radix + Custom 20-30 days Medium (more upfront work) Low (stable primitives)
shadcn/ui 20-30 days Medium (Tailwind adoption) Low (you own the code)
Mantine 15-20 days Low (familiar patterns) Low (stable API history)

Recommendation: Plan a dedicated 3-4 week sprint. Migration cannot be done incrementally. Consider whether Mantine or another library might offer a smoother path with better long-term stability.

Test plan

  • Review the migration plan document for accuracy and completeness
  • Validate effort estimates against team experience
  • Discuss alternative library options with team
  • Confirm the migration strategy aligns with project priorities

🤖 Generated with Claude Code

Document the scope and effort required to upgrade from Chakra UI v2.8.2
to v3. The analysis covers current usage (83 files, 45+ components),
major breaking changes, and provides an estimated 15-25 day effort
for the migration.

Key findings:
- Theme system requires complete rewrite (extendTheme → createSystem)
- Components restructured to compound pattern (Modal → Dialog.Root)
- Boolean props renamed (isOpen → open, isDisabled → disabled)
- @chakra-ui/icons removed, requires migration to lucide-react
- No incremental migration path due to provider conflicts

Also includes detailed comparison of alternative libraries (Mantine,
Radix UI, shadcn/ui) since migration effort may be comparable to
switching libraries entirely.
