Cheshire is a high-performance JSON encoding and decoding library for Clojure, built atop Jackson to combine fast parsing/generation with advanced support for types like Dates, UUIDs, Sets, Symbols, and the binary JSON SMILE format.

Features

  • Fast JSON encoding and decoding leveraging Jackson for speed
  • Supports rich Clojure data types: Date, UUID, Set, Symbol, with custom encoders
  • Provides SMILE format support for binary JSON serialization
  • Flexible encoding options like pretty-printing, key transformations, and ASCII escaping
  • Streaming-based parsing and generation—support for parse-stream, parsed-seq, and SMILE variants
  • Widely adopted in the ecosystem (e.g. included in Babashka) and praised for both performance and ease of use
