WebGear - Composable, type-safe HTTP APIs with Haskell Arrows

Submitted Sep 11, 2025

You might have heard about functors and monads in Haskell, but not much about arrows. While they are underutilized, arrows can be very handy for the right use-cases. This talk will introduce the concept of arrows and how they are used in the WebGear library to build composable, type-safe HTTP APIs.

Prerequisite: Basic understanding of Functors and Monads in Haskell
