Class up Your Config

Explore the intricacies of configuring production applications with Case Classy, a small but powerful library designed to simplify the process of loading and decoding configuration data. Dive into this 38-minute conference talk from Scala Days Copenhagen 2017, where Andy Scott demonstrates how Case Classy prevents all-or-nothing runtime errors and provides comprehensive error handling. Learn about the functional programming foundations that enable the assembly and combination of decoders for error accumulation. Discover how Shapeless and generic programming can automatically generate decoders, saving developers from extensive boilerplate. The presentation covers the project overview, goals, problems addressed, mathematical key concepts, arrows and decoders, decoding techniques, loading nested paths, and concludes with a Q&A session.
