    close()

    This handler implements the ClosableHandlerInterface and does internal cleanup work. When closed, it also closes its wrapped handler (if applicable).

    You usually don't want to call this method manually. It is done automatically when a Node.js process exits / a browser page is closed.

    getAcceptedLevels()

    Get an array of accepted log levels.

    processors

    This handler supports processors by implementing the ProcessableHandlerInterface.

    reset()

    This handler implements the ResettableInterface. Resetting it resets all attached processors and the wrapped handler (if applicable).

    You usually don't want to call this method manually on an individual handler. Consider calling it on the logger instead.

    setAcceptedLevels(minLevel, maxLevel)

    Set the range of accepted log levels.
