checkAppVersionUpgrade({ storage: AsyncStorage, considerInstallAsUpgrade: true }).then(
  ({ wasUpgraded }) => {
    if (wasUpgraded) {
      // for example copy asserts
    }
  },
);

checkAppVersionUpgrade({ storage: AsyncStorage }).then(
  ({ prevBuildNumber, buildNumber }) => {
    if (prevBuildNumber < 10 && buildNumber >= 10) {
      // for example do migrations on app upgrade
    }
  },
);

API

Signature:

checkAppVersionUpgrade({{ storage: object, considerInstallAsUpgrade: bool }}): Promise

storage is required.

considerInstallAsUpgrade is optional. Default is false. true value sets wasUpgraded to true when the app has just been installed.

Returns: Promise with object { wasUpgraded, version, buildNumber, prevVersion, prevBuildNumber}.

wasUpgraded is true on first session after app upgrade.
