  • Easy to read, fast to parse
  • Simple specifications

Specifications

Specification document: SPEC.md

Usage

Add the dependency to your shard.yml:

dependencies:
  con:
    github: j8r/con

This object is a convenient container.

A CON::Any can be converted back to either a CON or JSON serialized String

require "con"

con_any = CON.parse con_data
con_any.to_con

require "json"
con_any.to_json

CON::PullParser can be used to parse more efficiently, if the mapping is known in advance.

See spec for more test examples.

Benchmarks

There are benchmarks comparing CON and the stdlib's JSON implementation

crystal run --release benchmark/*
