By default, Flask will not log anything for us anywhere, except for the errors with their stack traces, which are sent to the logger (we will see more of this in the rest of the chapter). It does create a lot of stack traces while we run the application in the development mode using run.py, but, in production systems, we don't have this luxury. Thankfully, the logging library provides a whole lot of log handlers, which can be used as per requirements. In this recipe, we will understand how the logging library can be leveraged to ensure that effective logs are being captured from Flask applications.

Overview of this book
Flask, the lightweight Python web framework, is popular thanks to its powerful modular design that lets you build scalable web apps. With this recipe-based guide, you’ll explore modern solutions and best practices for Flask web development.
Updated to the latest version of Flask and Python 3, this second edition of Flask Framework Cookbook moves away from some of the old and obsolete libraries and introduces new recipes on cutting-edge technologies. You’ll discover different ways of using Flask to create, deploy, and manage microservices. This Flask Python book starts by covering the different configurations that a Flask application can make use of, and then helps you work with templates and learn about the ORM and view layers. You’ll also be able to write an admin interface and get to grips with debugging and logging errors. Finally, you’ll learn a variety of deployment and post-deployment techniques for platforms such as Apache, Tornado, and Heroku.
By the end of this book, you’ll have gained all the knowledge you need to confidently write Flask applications and scale them using standard industry practices.
