In our stock ticker application, we can modularize our application into two 'concerns'. A better mental model for Blueprints is to think of them as a collection of routes that needs to be 'mounted' to an existing Flask application. Blueprints are well suited for each of these because they allow routes to share a common routing prefix (for example /api) while also being able to modularize the logic and templates.Ĭommon Misunderstanding: Blueprints may look like separate Flask apps that happen to be imported into the server, but they are not. Each part of that application will often have its own URL routing scheme (/user, /admin, /api) and its own templates and logic. For example an application that has an user facing webpage, an administrative dashboard, and an API could have one blueprint for each of those parts of the website.

This is helpful if you are designing multiple separate components of a web application. As our application gets larger, it's going to be harder to continue to do that.īlueprints allow developers to create modules that define routes and are then imported into the main server. So far, we've been putting all of our server logic into one file, server.py.
