Major version upgrade from TailwindCSS v3 to v4 may introduce breaking changes

Category
Correctness
Code Snippet
package.json lines 32 and pnpm-lock.yaml dependencies:

  • "tailwindcss": "^3.4.16",
  • "tailwindcss": "^4.1.11",
    Recommendation
    Before merging, verify that:
  1. All TailwindCSS configurations are compatible with v4
  2. Custom CSS classes and @apply directives still work
  3. Build process and PostCSS plugins are compatible
  4. Run comprehensive testing on all UI components
  5. Check if any TailwindCSS plugins need updates for v4 compatibility
    Reasoning
    TailwindCSS v4 introduced significant architectural changes and potential breaking changes that could break existing styling and build processes
Missing documentation for major dependency upgrade impact

Category
Maintainability
Code Snippet
The PR only contains automated dependency bump without migration notes
Recommendation
Add documentation or migration notes covering:

  1. Key breaking changes from v3 to v4
  2. Any configuration files that need updating
  3. Testing checklist for UI regression
  4. Rollback plan if issues are discovered
    Reasoning
    Major version upgrades should be accompanied by proper documentation to help team members understand the impact and potential issues
Verify build performance impact of TailwindCSS v4 upgrade

Category
Performance
Code Snippet
Package upgrade from [email protected] to [email protected]
Recommendation
Benchmark build times and bundle sizes before and after the upgrade:

  1. Measure CSS compilation time
  2. Compare final CSS bundle size
  3. Test hot reload performance in development
  4. Verify production build optimization still works as expected
    Reasoning
    TailwindCSS v4 includes a new engine that may have different performance characteristics, and build performance regressions could impact developer experience
