Ep 066: Compose the Codec

Functional Design in Clojure

Each week, we discuss a different topic about Clojure and functional programming.

If you have a question or topic you'd like us to discuss, tweet @clojuredesign, send an email to [email protected], or join the #clojuredesign-podcast channel on the Clojurians Slack.

This week, the topic is: "Making middleware to handle JSON." We reinvent the wheel, and along the way discover a few reasons why you might want to do so as well.

Selected quotes:

• "Ring's choice: all of HTTP is a function."
• "Every concern is a function you compose in."
• "It's like a bucket brigade with the request."
• "Solving JSON encoding and decoding is a cross-cutting concern."
