Flask doesn't, but this is actually documented in its most basic form in Patterns for Flask: Lazy Loading. But when you have 529 routes like my main application has, then you definitely need multiple blueprints just to manage and organize all of them. py and have them integrated into your main application by using blueprints. py file with these contents: Move db out to a separate module; the Flask patterns documentation you link to has a separate database. Normally what we do is put all the content (routes, data models, validator classes, etc) in one single file called App. For example, let’s create a simple Flask app with two routes, each defined in a Learn how to effectively organize your Flask application by splitting it into multiple files using Blueprints. If you also want to match the root directory (a leading slash and empty path), you can add another rule that sets a default Flask-RESTful is designed to implement RESTful APIs specifically by interpreting the HTTP Request method. My file directory and what I have tried is as follows. from flask import Flask from flask.
