Very fast way to patch ReactNative Native libraries

For example, you can change the native code of react-native-firebase

install patch-package from here

yarn add --dev patch-package

make a change inside the native code

eg. code node_modules/react-native-firebase/ios/RNFirebase/notifications/RNFirebaseNotifications.m

make patch

patch-package react-native-firebase

add post-install script

eg. "postinstall": "patch-package && ./scripts/postinstall.sh",

and enjoy your fix :D

probably CircleCI require more love from you, but you can check the package documentation
