Flask Framework Cookbook - Second Edition

By: Shalabh Aggarwal

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.

Deploying with Apache

In this recipe, we will learn how to deploy a Flask application with Apache, which is, arguably, the most popular HTTP server. For Python web applications, we will use mod_wsgi, which implements a simple Apache module that can host any Python applications that support the WSGI interface.

Remember that mod_wsgi is not the same as Apache and needs to be installed separately.

Getting ready

We will start with our catalog application and make appropriate changes to it to make it deployable using the Apache HTTP server.

First, we should make our application installable so that our application and all its libraries are on the Python load path. This can be done using a setup.py script, as shown in the Making...
