Working with React Native can sometimes require clearing various caches to resolve issues or replicate bugs that occur on the first run. This guide will provide you with a comprehensive approach to effectively clearing caches in your React Native projects, particularly focusing on Android development.
Common Cache Types in React Native Development
In React Native development, several caches can be involved when building your application:
- React Native Packager Cache
- Emulator Cache
- Java Side Cache (e.g.,
.gradle
folder for Android) - NPM Cache
Step-by-Step Cache Clearing Process
Below are the steps to clear these caches effectively:
1. React Native Cache
For React Native projects, you can reset the cache using the following command:
react-native start --reset-cache
2. NPM Cache
To clear the NPM cache, especially if you are not using Expo, use:
npm start -- --reset-cache
3. Expo Projects
If you are using Expo, the command to clear the cache is:
expo start -c
4. Android Specific Cache
For Android projects, you might also need to clear the Gradle build cache:
cd android && ./gradlew cleanBuildCache
5. Comprehensive Cache Clearing
For a thorough cache clearing process, especially if you face persistent issues, consider executing the following commands:
watchman watch-del-all
rm -rf node_modules/
rm -rf $TMPDIR/react-native-packager-cache-*
rm -rf $TMPDIR/metro-bundler-cache-*
npm cache clean --force
npm install
npm start --reset-cache
Additional Tips
Ensure that you are also cleaning the build folders in your IDEs:
- For iOS, navigate to Xcode and select Product > Clean Build Folder.
- For Android, in Android Studio, go to Build > Clean Project.
