that take a user-suppiled lambda to generate the data needed to render our desired compile-time resource! These are e�ectively templated functions, but we will use the cleaner auto parameter syntax for

effective. Routes based on URI templates RFC REST-inspired mapping of URIs to resources Global, resource, and method hooks Idiomatic HTTP error responses Full Unicode support Intuitive request and response authorize the request, taking into account the user’s role and the requested resource. Why doesn’t Falcon create a new Resource instance for every request? Falcon generally tries to minimize the number second to reduce memory usage. Therefore, when adding a route, Falcon requires an instance of your resource class, rather than the class type. That same instance will be used to serve all requests coming

Tip The Talons project [https://github.com/talons/talons] maintains a collection of auth plugins for the Falcon framework.
