Summary
This was a dense chapter. We overviewed important concepts—such as performance and maintainability, productivity, and quality—had a quick discussion about premature optimization and overengineering, and focused our efforts on learning how to write better code with Flask.
Blueprints, which allow you to create robust large projects with Flask, were discussed with a full-range example; we learned about logging to file and mail and the importance of each, had a lovely time with Flask-DebugToolbar (so handy!) and took the default session setup and usage to heart.
You're now a capable Flask developer. I'm so proud!
As one first learns to drive before trying out drifting, we will begin our Flask drifting next chapter. Our focus will be on using the wide extension ecosystem available to Flask in order to create amazing projects. It will be lots of fun! See you there!
