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

You can clean cache in React Native >= 0.50 and npm > 5 :

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

Apart from cleaning npm cache you might need to reset simulator or clean build etc.
