Blueprints¶
Even though many basic apps don’t require them I recommend looking into using blueprints to structure your app.
The benefits inclue:
- Easier to follow code with related views kept together
- Code re-usability, blueprints are very self contained (e.g.g templates and behaviour such as authentication)
Creating a blueprint involves:
- Using flask.Blueprint instead of flask.Flask for your blueprint
- Registering it in your app using app.register_blueprint
Code¶
Blueprints let you compose your application from components
-
pythonie.blueprints.blueprints.

For reference here’s the application index (and implied link back to the source). You’ll notice some use of configuration in that code too.
