ExceptionManager is an utility class who can insert or erase custom error class with
its convertion method to a regular nest.HttpException instance.
If you define an API function through TypedRoute or EncryptedRoute
instead of the basic router decorator functions like nest.Get or
nest.Post and the API function throws a custom error whose class has been
inserted in this EntityManager, the error would be
automatically converted to the regular nest.HttpException instance by the
ExceptionManager.Closure function.
Therefore, with this ExceptionManager and TypedRoute or EncryptedRoute,
you can manage your custom error classes much systemtically. You can avoid 500 internal
server error or hard coding implementation about the custom error classes.
Below error classes are defaultly configured in this ExceptionManager
Exception manager for HTTP server.
