How to clear react-native cache?

Question

In react-native development, there are multiple caches used when the app is built:

1. React-native packager cache
2. Emulator cache
3. Java side cache

Answer 1

Clearing the Cache of your React Native Project:

npm < 6.0 and RN < 0.50:

 watchman watch-del-all && rm -rf $TMPDIR/react-* &&
 rm -rf node_modules/ && npm cache clean && npm install && 
 npm start -- --reset-cache

npm >= 6.0 and RN >= 0.50:

 watchman watch-del-all && rm -rf $TMPDIR/react-native-packager-cache-* &&
 rm -rf $TMPDIR/metro-bundler-cache-* && rm -rf node_modules/ && npm cache clean --force &&
 npm install && npm start -- --reset-cache
