Using Smart NgRX Error Handling

Error Handling

From time to time, SmartNgRX will catch errors and fail gracefully. But, you will probably still want to know they occurred.

For this, we've created a service token that you can use to register your own class which we will use to notify your code of the error.

The token you'll need to import is smartNgRXErrorHandlerToken and you'll want your class to implement SmartNgRXErrorHandler which has one method handleError.

handleError takes two arguments:

  • message: A string that describes where the error originated
  • error: The error that occurred as caught by the exception handler
