47. Interceptors, part 1, concepts

The Interceptor pattern was originally introduced by Pedestal, but has since been adopted by several other projects in the Clojure world. It’s an extremely useful design tools to be familiar with, and while they may seem a bit strange at first, Interceptors are suprisingly straightforward.

This episode introduces the interceptor concept, including the context map, queue, and stack. Clojure’s persistent queues are explored, and to round off we look at how interceptors deal with error handling.
