[Flask Framework Cookbook](https://www.packtpub.com/web-development/flask-framework-cookbook-second-edition?utm_source=github&utm_medium=repository&utm_campaign=9781789951295), published by Packt. 9 | 10 | **Over 80 proven recipes and techniques for Python web development with Flask** 11 | 12 | ## What is this book about? 13 | Flask, the lightweight Python web framework, is popular due 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. 14 | 15 | This book covers the following exciting features: 16 | * Explore web application development in Flask, right from installation to post-deployment stages 17 | * Make use of advanced templating and data modeling techniques 18 | * Discover effective debugging, logging, and error handling techniques in Flask 19 | * Integrate Flask with different technologies such as Redis, Sentry, and MongoDB 20 | * Deploy and package Flask applications with Docker and Kubernetes 21 | 22 | If you feel this book is for you, get your [copy](https://www.amazon.com/dp/1789951291) today! 23 | 24 | https://www.packtpub.com/ 26 | 27 | 28 | ## Instructions and Navigations 29 | All of the code is organized into folders. For example, Chapter02. 30 | 31 | The code will look like the following: 32 | ``` 33 | from flask import Flask 34 | app = Flask(__name__) 35 | 36 | @app.route('/') 37 | def hello_world(): 38 | return 'Hello to the World of Flask!' 39 | 40 | if __name__ == '__main__': 41 | app.run() 42 | ``` 43 | 44 | **Following is what you need for this book:** 45 | 46 | If you are a web developer who wants to learn more about developing scalable and production-ready applications in Flask, this is the book for you. You’ll also find this book useful if you are already aware of Flask's major extensions and want to use them for better application development. Basic Python programming experience along with basic understanding of Flask is assumed. 47 | 48 | With the following software and hardware list you can run all code files present in the book (Chapter 1-13). 49 | 50 | ### Software and Hardware List 51 | 52 | | Chapter | Software required | OS required | 53 | | -------- | ------------------------------------ | -----------------------------------| 54 | | 1 | Flask, Virtualenv, virtualenvwrapper | Windows, Mac OS X, and Linux (Any) | 55 | | 2 | Twitter Bootstrap, ccy, Moment.js | Windows, Mac OS X, and Linux (Any) | 56 | | 3 | Flask-sqlalchemy, requests, | Windows, Mac OS X, and Linux (Any) | 57 | | | Redis, Flask-Migrate, Flask-mongoengine, | | 58 | | 4 | - | - | 59 | | 5 | Wtforms, Flask-WTF | Windows, Mac OS X, and Linux (Any) | 60 | | 6 | Flask-Login, pyOpenSSL, Flask-Dance, | Windows, Mac OS X, and Linux (Any) | 61 | | | python-ldap | | 62 | | 7 | Flask-Restful, requests | Windows, Mac OS X, and Linux (Any) | 63 | | 8 | Flask-Admin, CKEditor.js | Windows, Mac OS X, and Linux (Any) | 64 | | 9 | Flask-Babel | Windows, Mac OS X, and Linux (Any) | 65 | | 10 | sentry-sdk, Nose, geoip2, Coverage | Windows, Mac OS X, and Linux (Any) | 66 | | 11 | mod_wsgi, Nginx, uwsgi, gunicorn, | Windows, Mac OS X, and Linux (Any) | 67 | | | supervisor, Tornado, boto3, newrelic, | | 68 | | | Heroku CLI, AWS Elastic Beanstalk setup | | 69 | | 12 | Docker, Minikube, zappa | Windows, Mac OS X, and Linux (Any) | 70 | | 13 | Flask-WhooshAlchemy, elasticsearch python | Windows, Mac OS X, and Linux (Any) | 71 | | | library, Elasticsearch, Flask-Caching, | | 72 | | | Flask-Mail, Celery | | 73 | 74 | We also provide a PDF file that has color images of the screenshots/diagrams used in this book.
