How to clear react-native cache?
JavascriptJavaAndroidReactjsReact NativeJavascript Problem Overview
In react-native development, there are multiple caches used when the app is built:
- React-native packager cache
- Emulator cache
- Java side cache (.gradle) folder (only in android)
- npm cache (if relevant?)
Am I missing something also? Because I'm trying to clear cache in react-native, to be able to repeat a bug that only occurs on first usage. But clearing those caches above did not help. This is on android. When the app is building, most of the rows DO NOT say UP-TO-DATE, as expected, because I cleared the cache.
But, there are still many rows where this text is printed. Like:
> app:preBuild UP-TO-DATE > > app:preDebugBuild UP-TO-DATE > > :app:preReleaseBuild UP-TO-DATE
The question is, how can I clear the whole cache related to react-native development?
Javascript Solutions
Solution 1 - Javascript
For React Native Init approach (without expo) use:
npm start -- --reset-cache
Solution 2 - Javascript
Simplest one(react native,npm and expo )
For React Native
react-native start --reset-cache
for npm
npm start -- --reset-cache
for Expo
expo start -c
Solution 3 - Javascript
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
Solution 4 - Javascript
try this
react-native start --reset-cache
Solution 5 - Javascript
For those who are using expo-cli
> expo start -c
Solution 6 - Javascript
Currently, it is built using npx, so it needs to be updated.
Terminal : npx react-native start --reset-cache
IOS : Xcode -> Product -> Clean Build Folder
Android : Android Studio -> Build -> Clean Project
Solution 7 - Javascript
This is what works for me:
watchman watch-del-all && rm -f podfile.lock && rm -rf node_modules && yarn && yarn start --reset-cache
Solution 8 - Javascript
Below commands worked for me for Android and Yarn,
cd android && ./gradlew cleanBuildCache && cd .. &&
watchman watch-del-all && rm -rf node_modules/ &&
rm -rf $TMPDIR/react-native-packager-cache-* &&
rm -rf $TMPDIR/metro-bundler-cache-* &&
yarn cache clean && yarn install &&
yarn start --reset-cache

Here's a great discussion on GitHub which helped me a lot. Clearing the Cache of your React Native Project by Jarret Moses
There are solutions for 4 different instances.
-
RN <0.50 -
watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf node_modules/ && npm cache clean && npm install && npm start -- --reset-cache -
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 && npm install && npm start -- --reset-cache -
NPM >=5 -
watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf node_modules/ && npm cache verify && npm install && npm start -- --reset-cache -
Windows -
del %appdata%\Temp\react-native-* & cd android & gradlew clean & cd .. & del node_modules/ & npm cache clean --force & npm install & npm start -- --reset-cache
The solution is similar to Vikram Biwal's Answer.
And there is a discussion below in the given link, so even if the above 4 cases don't work for you, you can scroll through and find a possible solution.
Solution 10 - Javascript
If you are using WebStorm, press configuration selection drop down button left of the run button and select edit configurations:
Double click on Start React Native Bundler at bottom in Before launch section:
Enter --reset-cache to Arguments section:
Solution 11 - Javascript
Clearing the Cache of your React Native Project: if you are sure the module exists, try this steps:
- Clear watchman watches: npm watchman watch-del-all
- Delete node_modules: rm -rf node_modules and run yarn install
- Reset Metro's cache: yarn start --reset-cache
- Remove the cache: rm -rf /tmp/metro-*
Solution 12 - Javascript
Have you tried gradle cleanBuildCache?
https://developer.android.com/studio/build/build-cache.html#clear_the_build_cache
Solution 13 - Javascript
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.

Well.. i want to share my experience about this issue:
I was facing this problem, and when I opened the task manager I notice many tasks being executed, and they were linked to my project folder.
So I restarted my PC, and when it turned on, I could install all I needed, so the problem got solved itself, it worked to me, hope this help somebody...
Solution 15 - Javascript
I had a similar problem, I tried to clear all the caches possible (tried almost all the solutions above) and the only thing that worked for me was to kill the expo app and to restart it.
Solution 16 - Javascript
I went into this issue today, too. The cause was kinda silly -- vscode auto imported something from express-validator and caused the bug.
Just mentioning this in case anyone has done all the steps to clear cache/ delete modules or what not.
Solution 17 - Javascript
Run in your terminal: expo prebuild --clean
Solution 18 - Javascript
TO Clear cache in IOS/Xcode
Delete folders in
/Users/{YOUR_USERNAME}/Library/Developer/Xcode/DerivedData/
and try again.
rm ~/Library/Developer/Xcode/DerivedData/*
