console_log
This module provides a WSGI middleware that allows you to log to the browser console from Python:
import logging
from flask import Flask
from console_log import ConsoleLog
console = logging.getLogger('console')
console.setLevel(logging.DEBUG)
app = Flask(__name__)
@app.route('/')
def hello():
logger.error('Error logged from Python')
logger.warning('Warning logged from Python')
logger.info('Info logged from Python')
logger.debug('Debug logged from Python')
logger.debug({'foo': ['bar', 'baz']})
return "Hello World!"
app.wsgi_app = ConsoleLog(app.wsgi_app, console)The logged messages will then show up in the browser console:
How it works
The new WSGI app does two things:
- Creates a websocket backchannel.
- Injects Javascript code into HTML responses, fetching data from the websocket channel and logging them to console.
