.. _how_to_log: Logging ======= Quart has a standard Python logger sharing the same name as the ``app.name``. To use it, simply make use of :attr:`~quart.app.Quart.logger`, for example: .. code-block:: python app.logger.info('Interesting') app.logger.warning('Easy Now') Configuration ------------- The Quart logger is not created until its first usage, which may occur as the app is created. These loggers on creation respect any existing configuration. This allows the loggers to be configured like any other python logger, for example .. code-block:: python from logging.config import dictConfig dictConfig({ 'version': 1, 'loggers': { 'quart.app': { 'level': 'ERROR', }, }, }) Disabling/removing handlers --------------------------- The handler :attr:`~quart.logging.default_handler` attached to the quart logger can be removed like so, .. code-block:: python from logging import getLogger from quart.logging import default_handler getLogger(app.name).removeHandler(default_handler)
