Function	`wsgi_errors_stream`	Find the most appropriate error stream for the application. If a request is active, log to ``wsgi.errors``, otherwise use ``sys.stderr``.
Variable	`default_handler`	Undocumented

def create_logger(app: Flask) -> logging.Logger: (source) ¶

Get the Flask app's logger and configure it if needed. The logger name will be the same as :attr:`app.import_name <flask.Flask.name>`. When :attr:`~flask.Flask.debug` is enabled, set the logger level to :data:`logging.DEBUG` if it is not set. If there is no handler for the logger's effective level, add a :class:`~logging.StreamHandler` for :func:`~flask.logging.wsgi_errors_stream` with a basic format.

def has_level_handler(logger: logging.Logger) -> bool: (source) ¶

Check if there is a handler in the logging chain that will handle the given logger's :meth:`effective level <~logging.Logger.getEffectiveLevel>`.

@LocalProxy
def wsgi_errors_stream() -> t.TextIO: (source) ¶

Find the most appropriate error stream for the application. If a request is active, log to ``wsgi.errors``, otherwise use ``sys.stderr``. If you configure your own :class:`logging.StreamHandler`, you may want to use this for the stream. If you are using file or dict configuration and can't import this directly, you can refer to it as ``ext://flask.logging.wsgi_errors_stream``.
