Production Haskell Demystified

" summary

Haskell code models produce concrete artifacts automatically: using GHC Generics plus libraries like generic-random and Aeson the compiler derives QuickCheck arbitrary instances, JSON codecs, round‑trip property tests (the demo runs ~100 property tests and uses golden files in VCS) and generates Swagger docs plus a mock API. A ~250-line server produces live random JSON examples and failing tests flag breaking schema changes, so the system both documents and validates formats with little handwritten glue.
