Heads up! TypeScript types need special attention! 🤔
The TypeScript types upgrade might require code changes due to stricter type checking in React 19.
Consider:
- Running a full TypeScript check after the upgrade
- Testing with
--strictflag enabled - Reviewing deprecated type patterns
28-29:
Yo! Hold up! We need to verify React 19 compatibility with other deps! 🍝
The upgrade to React 19 is major and we gotta make sure our other dependencies can handle it, especially MUI v6.
Before merging:
- Check MUI's React 19 compatibility status
- Review React 19's breaking changes
- Plan a testing strategy for the upgrade
✅ Verification successful
Yo dawg, we're good to go with React 19! 🍝
Looking at the dependencies, everything's lined up perfectly:
- MUI v6.2.0 and its ecosystem are already prepped for React 19
- React ecosystem packages (react-redux 9.2.0, react-router 6.23.x, react-toastify 10.0.5) are all at versions that support React 19
- Dev dependencies are properly aligned with React 19 types
The upgrade's as clean as mom's kitchen after cooking that spaghetti! 🍝
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check package.json files for potential peer dependency conflicts
fd package.json --exec jq -r '.peerDependencies | select(."react" != null) | ."react"' {} \;
# Check for React 19 compatibility issues in package-lock.json
fd package-lock.json --exec jq -r '.. | select(.name? and .peerDependencies?.react?) | {name, react: .peerDependencies.react}' {} \;
Length of output: 235
Script:
#!/bin/bash
# Let's check the actual dependencies in package.json
cat Client/package.json | jq '.dependencies'
# Let's also check devDependencies for any React-related stuff
cat Client/package.json | jq '.devDependencies'
# Search for any React imports in the codebase to understand usage patterns
rg -l "from ['|\"]react" --type ts --type tsx --type jsx
# Look for any MUI imports to verify its usage
rg -l "from ['|\"]@mui/" --type ts --type tsx --type jsx
