setLogLevel

• setLogLevel(logLevel: LogLevelString): void

  Set the log level across all modules. Only applies to iOS currently, has no effect on Android. Should be one of 'error', 'warn', 'info', or 'debug'. Logs messages at the configured level or lower (less verbose / more important). Note that if an app is running from AppStore, it will never log above info even if level is set to a higher (more verbose) setting. Note that iOS is missing firebase-js-sdk log levels 'verbose' and 'silent'. 'verbose' if used will map to 'debug', 'silent' has no valid mapping and will return an error if used.

  Parameters

  • logLevel: LogLevelString

  Returns void

setReactNativeAsyncStorage

• setReactNativeAsyncStorage(asyncStorage: ReactNativeAsyncStorage): void

  The AsyncStorage implementation to use for persisting data on 'Other' platforms. If not specified, in memory persistence is used.

  This is required if you want to persist things like Auth sessions, Analytics device IDs, etc.

  Parameters
