Latest version

Quickstart

(require '[jsonista.core :as jsonista])

(jsonista/write-value-as-string {:hello 1})
;; => "{\"hello\":1}"

(def +data+ (jsonista/write-value-as-string {:foo "bar"}))

(jsonista/read-value +data+)
;; => {"foo" "bar"}

Performance

• All standard encoders and decoders are written in Java
• Protocol dispatch with read-value & write-value
• Jackson ObjectMapper is used directly
• Small functions to support JVM Inlining

See perf-tests for details.
