js-unixfsv2

This library is a full implementation of unixfs-v2 for JavaScript.

encoder(path, options={})

Async generator that yields blocks for every file and and directory in the path.

Last block is the root block.

Runs recursively through directories. Accepts any valid file or directory string path.

const { encoder } = require('unixfsv2')
const storage = require('any-key-value-store')

const putBlock = async b => storage.put((await b.cid()).toString(), b.encode())

const storeDirectory = async path => {
  for await (const { block, root } of encoder(__dirname)) {
    await storage.putBlock(block || root.block())
    if (root) return root.block().cid()
  }
}

reader(rootBlock, getBlock)

Returns a new Reader instance for the root block.

const { reader } = require('unixfsv2')
const storage = require('any-key-value-store')
const Block = require('@ipld/block')

const getBlock = async cid => Block.create(await storage.get(cid.toString()), cid)

/* rootBlock would be the same as the last block in
/  encode example.
*/
const r = reader(rootBlock, getBlock)
