How to read json input in stdin ?

Question

I need to read json line input in stdin

Example INPUT

{ "foo" : "bar" }

{ "foo" : "bar" }

Answer 1

1. Use (read-line) to read single line from *in*
2. Use any json parser to parse this string.

Example using jsonista:

$ clj -Sdeps '{:deps {metosin/jsonista {:mvn/version "0.2.4"}}}'
Clojure 1.10.0
user=> (require '[jsonista.core :as j])
nil
user=> (j/read-value (read-line))
{"foo": "bar"}
{"foo" "bar"}
