React Native maintenance commands

Generate native projects

npx expo prebuild
npx expo prebuild --platform ios
npx expo prebuild --platform android

Prebuild can regenerate native files. Commit or back up intentional native changes before running destructive regeneration commands.

Clear development caches

watchman watch-del-all
rm -rf $TMPDIR/react-native-packager-cache-*
rm -rf $TMPDIR/metro-cache

Reinstall JavaScript dependencies

rm -rf node_modules package-lock.json
npm cache clean --force
npm install

Clean native projects

cd android && ./gradlew clean && cd ..
cd ios && pod cache clean --all && rm -rf Pods Podfile.lock && pod install && cd ..

Review every removal command before running it and execute it only from the intended project directory.
