DAGService - The DAGService offers an interface to interact directly with a MerkleDAG object (composed by one or more DAGNodes that are linked), using the BlockService to store and fetch the DAGNodes as it needs them

BlockService - The BlockService uses IPFS Repo as the local datastore for blocks and an IPFS Exchange compliant implementation to fetch blocks from the network.

A DAGNode and a Block are data structures made available by this module.

Usage

$ npm i ipfs-merkle-dag

const ipfsMDAG = require('ipfs-merkle-dag')

// then, to access each of the components
ipfsMDAG.DAGService
ipfsMDAG.DAGNode
ipfsMDAG.BlockService
ipfsMDAG.Block
