@ipld/dag-cbor

JS implementation of dag-cbor.

This is the new interface meant for use by itself or with multiformats and @ipld/block. It is not used by js-ipld-format which is currently used in IPFS. That library is here.

Usage:

import { encode, decode } from '@ipld/dag-cbor'
import { CID } from 'multiformats'

const obj = {
  x: 1,
  /* CID instances are encoded as links */
  y: [2, 3, CID.parse('QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4')],
  z: {
    a: CID.parse('QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4'),
    b: null,
    c: 'string'
  }
}

let data = encode(obj)
let decoded = decode(data)
decoded.y[0] // 2
CID.asCID(decoded.z.a) // cid instance

Spec

The dag-cbor specification is in the IPLD specs repo.
