This book is a collection of the best practices for using Flask. There are a lot of pieces to the average Flask application. You’ll often need to interact with a database and authenticate users, for example. In the coming pages I’ll do my best to explain the “right way” to do this sort of stuff. My recommendations aren’t always going to apply, but I’m hoping that they’ll be a good option most of the time.



Explore Flask is a book about best practices and patterns for developing web applications with Flask. The book was funded by 426 backers on Kickstarter in July 2013.



I finally released the book, after spending almost a year working on it. Almost immediately I was tired of managing distribution and limiting the book’s audience by putting it behind a paywall. I didn’t write a book to run a business, I wrote it to put some helpful content out there and help grow the Flask community. An HTML version is at https://exploreflask.com/
