Issue: MUI v7 deprecated the old Grid API with 'item', 'xs', 'sm', 'md' props.
Warnings: 'The item prop has been removed', 'The xs/sm/md props have been removed'
Solution: Migrate to Grid2 component with new 'size' prop:
- Changed Grid import to Grid2 (aliased as Grid)
- Removed 'item' prop from all Grid components
- Changed xs={6} sm={4} md={2} to size={{ xs: 6, sm: 4, md: 2 }}
Reference: https://mui.com/material-ui/migration/upgrade-to-grid-v2/
All Grid warnings now resolved.
Issue: After MUI v7 upgrade, Quick Actions and Today's Summary
cards were not evenly sized - they were content-sized instead.
Solution:
- Quick Actions: Added height: '100%' and flexbox layout to ensure
all cards are the same height within each row
- Today's Summary stats: Added minHeight: '120px' with flexbox to
ensure consistent card heights
Result: Both sections now have evenly spaced, consistent layouts
regardless of content length.
Issue: MUI v7 CircularProgress was causing hydration mismatch warnings
due to different CSS class names between server and client renders.
Solution: Only render the MUI loading component on the client side
using isClient state flag. This prevents SSR hydration issues while
maintaining the same functionality.
Changes:
- Added useState to track client-side rendering
- Conditionally render CircularProgress only on client
- Server now renders null for loading state (no hydration mismatch)
- @mui/material: 5.18.0 → 7.3.3
- @mui/icons-material: 5.18.0 → 7.3.3
- @mui/material-nextjs: 7.3.2 → 7.3.3
Server working correctly with MUI v7:
- All pages compile successfully
- HTTP 200 on all routes
- No MUI-related errors
- Next.js upgraded from 14.2.0 to 15.5.4
- React upgraded from 18 to 19.2.0
- react-dom upgraded from 18 to 19.2.0
Frontend server working correctly:
- Dev server starts successfully
- Pages compile without errors
- HTTP 200 responses on all routes
Next steps:
- Fix next.config.js warning (swcMinify is deprecated)
- Upgrade MUI packages
- Upgrade testing libraries
Created new eslint.config.mjs with flat config:
- Migrated from .eslintrc.js to eslint.config.mjs
- Added globals package for Node.js and Jest globals
- Configured TypeScript parser and plugins
- Maintained all existing rules and Prettier integration
ESLint now running successfully with v9 flat config.
Note: 39 unused variable warnings found - these are minor code
quality issues that can be addressed in a separate cleanup PR.
