Logging

Quart has a standard Python logger sharing the same name as the app.name. To use it, simply make use of logger, for example:

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

from logging.config import dictConfig

dictConfig({
    'version': 1,
    'loggers': {
        'quart.app': {
            'level': 'ERROR',
        },
    },
})

Disabling/removing handlers

The handler default_handler attached to the quart logger can be removed like so,

from logging import getLogger
from quart.logging import default_handler

getLogger(app.name).removeHandler(default_handler)
