setUp

yarn add react-native-ota-hot-update && react-native-blob-util

IOS

Open AppDelegate.m and add this:

#import "RNhotupdate.h"
...
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
  return [RNhotupdate getBundle]; ## add this line
#endif
}

Android

Open MainApplication.java and add these codes bellow:

import com.rnhotupdate.OtaHotUpdate;
...
  @Override
         public String getJSBundleFile() {
             return OtaHotUpdate.getBundleJS();
         }

1.Add these script into your package.json to export bundlejs file:

"scripts": {
  "export-android": "mkdir -p android/output && react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/output/index.android.bundle --assets-dest android/output  && cd android && find output -type f | zip index.android.bundle.zip -@ && cd .. && rm -rf android/output",
  "export-ios": "mkdir -p ios/output && react-native bundle --platform ios --dev false --entry-file index.js --bundle-output ios/output/main.jsbundle --assets-dest ios/output && cd ios && find output -type f | zip main.jsbundle.zip -@ && cd .. && rm -rf ios/output"
}

These commands are export bundle file and compress it as a zip file, one for android and one for ios. You can create your own script that export and auto upload to your server.

Then create an json file: update.json like that:

{
  "version": 1,
  "downloadAndroidUrl": "",
  "downloadIosUrl": ""
}
