Aeson Combinators

Build Status built with nix

Low overhead value space Decoder on top of Aeson's Parser for combinator style decoding.

This library is compatible with GHC as well as recent versions of GHCJS.

Performance

Decoder a type is a function Value -> Parser a the same as parseJSON member function of FromJSON class. This means there should be near zero overhead. Aeson types and functions are reused where possible. Similarly Encoder a type follow toJSON from ToJSON type class.

Simple benchmark shows that implementation using aeson-combinators performs better than equivalent derived instance and on par (actually even slightly better though with difference in noise range) with manually implemented instance.
