Intro to Decoders
summary
Library bs-decoders decodes JSON into custom Reason/OCaml domain types using composable combinators, not magic deriving. It gives contextual error messages (for example: while decoding a list in the second element expected int got true), supports variant dispatching and try-first decoders for ambiguous layouts, and provides a functor-based backend abstraction so the same decoders work with Yojson, Easy_json, BuckleScript, or native. Repo and npm package are available.
