Create web services that are lightweight, maintainable, scalable, and secure using the best tools and techniques designed for Python

About This Book

• Develop RESTful Web Services using the most popular frameworks in Python
• Configure and fine-tune your APIs using the best tools and techniques available
• This practical guide will help you to implement complete REST-based APIs from scratch

Who This Book Is For

This book is for web developers who have working knowledge of Python and would like to build amazing web services by taking advantage of the various frameworks of Python. You should have some knowledge of RESTful APIs.

What You Will Learn

• Develop complex RESTful APIs from scratch with Python combined with and without data sources
• Choose the most appropriate (micro) framework based on the specific requirements of a RESTful API / web service
• Debug, test, and profile RESTful APIs with each of the frameworks
• Develop a complex RESTful API that interacts with a PostgreSQL database
• Add authentication and permissions to a RESTful API built in each of the frameworks
• Map URL patterns to request handlers and check how the API works
• Profile an existing API and refactor it to take advantage of asynchronous code

In Detail

Python is the language of choice for millions of developers worldwide, due to its gentle learning curve as well as its vast applications in day-to-day programming. It serves the purpose of building great web services in the RESTful architecture. This book will show you the best tools you can use to build your own web services.

Learn how to develop RESTful APIs using the popular Python frameworks and all the necessary stacks with Python, Django, Flask, and Tornado, combined with related libraries and tools. We will dive deep into each of these frameworks to build various web services, and will provide use cases and best practices on when to use a particular framework to get the best results.

We will show you everything required to successfully develop RESTful APIs with the four frameworks such as request handling, URL mapping, serialization, validation, authentication, authorization, versioning, ORMs, databases, custom code for models and views, and asynchronous callbacks. At the end of each framework, we will add authentication and security to the RESTful APIs and prepare tests for it.

By the end of the book, you will have a deep understanding of the stacks needed to build RESTful web services.

Style and approach

The book takes a straightforward approach, not spending time getting you started with RESTful APIs and web services. It will give you the best use cases for each framework to build great web services in Python.

Acknowledgments

At the time of writing this book, I was fortunate to work with an excellent team at Packt Publishing , whose contributions vastly improved the presentation of this book. Reshma Raman and Aaron Lazar allowed me to provide them ideas to develop this book and I jumped into the exciting project of teaching how to use many popular web frameworks to develop RESTful Web Services with Python 3.5. Divij Kotian helped me realize my vision for this book and provided many sensible suggestions regarding the text, the format and the flow. The reader will notice his great work. It was great working with Divij in another book. In fact, it is the third book in which I was able to work with Reshma and Divij. It’s been great working with them in another project and I can’t wait to work with them again. I would like to thank my technical reviewers and proofreaders, for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. This book was possible because they gave valuable feedback.

Gebin George did a wonderful job when the book moved into the production stage. He has made all the necessary adjustments to generate the final version of the book with an outstanding layout. Gebin made the book easy to read in its different versions and made sure I was happy with the results. A book like this one with so many tables, figures, pieces of code, commands and sample outputs requires skilled people with eye for detail during all the stages. I was fortunate to have Gebin onboard. I would like to thank my technical reviewers and proofreaders, for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. This book was possible because they gave valuable feedback.

I usually start writing notes about ideas for a book when I spend time at software development conferences and events. I wrote the initial idea for this book in San Francisco, California, at Intel Developer Forum 2015. One year later, at Intel Developer Forum 2016, I had the chance to discuss with many software engineers the book I was finishing and incorporate their suggestions in the final drafts.

The entire process of writing a book requires a huge amount of lonely hours. I wouldn’t be able to write an entire book without dedicating some time to play soccer against my sons Kevin and Brandon, and my nephew, Nicolas. Of course, I never won a match. However, I did score a few goals.

About the Reviewer

Elmer Thomas completed a B.S. in Computer Engineering and a M.S. in Electrical Engineering at the University of California, Riverside. His focus was on Control Systems, specifically GPS navigation systems, spending several years serving as a research assistant, building software and hardware for self driving cars at U.C. Riverside and Berkeley, resulting in 2 co-publications: Aided Integer Ambiguity Resolution Algorithm and Data Fusion via Kalman Filter: GPS & INS. During the final years of his Masters program, he added a few mentors, partners and some business skills through the Tuck Executive Program at Dartmouth to his repertoire and co-founded several companies with varying degrees of success over the next 7 years. During this time he helped hundreds of business profit while achieving over 50 awards from local and state government for service in the community.
