It's easy to understand what is happening at first glance: the decorator is telling our that whenever a user visits our app domain ( ) at the given. Return "Hello World!" Flask's "Hello is a Python decorator that Flask provides to assign URLs in our app to functions easily. Views refer to the content to be served at these URLs, whether that be a webpage, an API response, etc.įlask's "Hello world" example defines a route listening at the root our app and executes a view function called home(): from flask import Flask Routes refer to URL patterns of an app (such as /home or / about). Defining Routes & ViewsĮvery web framework begins with the concept of serving content at a given URL. If you have any prior experience with MVC frameworks, you should be able to follow along just fine almost no previous knowledge of Flask is needed to keep up.

Today we're covering the finer details of how to define and build smart routes to accommodate dynamic applications and APIs. This is where we have the chance to be artistic. To build products larger than ourselves, we need to arm them with the ability to grow in ways we can't foresee, which means defining dynamic routing opportunities that can potentially grow endlessly. Apps are a medium for data such as user-generated content such as user profiles or author posts, and routes define the way our users will access data which is always changing. That perspective works fine for small-scale applications, but meaningful applications (or APIs) aren't static one-to-one mappings. As it turns out, I am apparently both and miserable enough to be the kind of person who writes tutorials about routing.Īt first glance, it's hard to imagine routing to be an "art." We'll typically reserve a URL path, such as / or /home, associate this with a page template, and serve said template to the user, perhaps with added business logic. It isn't often you find somebody sad or miserable enough to expand on such an inglorious feature. It's hard to imagine a more critical feature of web frameworks than routing: the humble act of mapping URLs to actions, such as serving pages or data.
