dag_json

The native JSON IPLD format is called DAG-JSON to disambiguate it from regular JSON. Most simple JSON objects are valid DAG-JSON. The primary differences are:

• Bytes and Links are supported with special use of single-key (“/”) map.
• In limited cases, maps with the key “/” other than those used to encode Bytes and Links, are disallowed.
• Maps are sorted by key.

gleam add dag_json@1

DAG-JSON is a specification of a binary format so dag_json.encode returns a BitArray DAG-JSON is a valid JSON document so decode using the json library. This library includes two decode helpers to return BitArray and Cid data types.

import dag_json

pub fn encode() {
  dag_json.binary(<<1, 2>>)
  |> dag_json.encode
}

pub fn decoder() {
  use bytes <- decode.field("foo", dag_json.decode_bytes)
  use ref <- decode.field("link",dag_json.decode_cid)
  todo
}
