Usage

importer(parts)

This method returns @ipld/block] instances for only the dag-pb nodes the UnixFSv1 importer creates. Since you are passing in the lengths and lengths of the raw blocks those are not returned.

const importer = require('unixfsv1-part-importer')
const CID = require('cids')
const raw = new CID('mAVUSIO7K3sMLqZPsJ/6SYMa5HiHBaj81xjniNYRUXbpKl/Ac') // CID of a raw node
const parts = [
  { cidVersion: 1, size: 138102, cid: raw }
]
const blocks = await importer(parts) // contains only the dag-pb nodes for unixfs
