level-blockstore

Blockstore implementation with a level backend for content addressable data in ipfs-car. It follows the ipfs-car Blockstore Interface.

Description

While packing files into Content Addressable aRchives (CAR), ipfs-car imports the given files into unix-fs. All the unix-fs graph needs to be computed, in order to get the root CID to create the resulting CAR file. This blockstore can be used to store the generated unix-fs temporarily, so that we can iterate them afterwards and create large CAR files.

This backend datastore can be used in Node.js, Electron and Browser environments.

Install

# install it as a dependency
$ npm i level-blockstore

Usage with ipfs-car

import { pack } from 'ipfs-car/pack'
import { LevelBlockStore } from 'ipfs-car/blockstore/memory'

const { root, out } = await pack({
  input: [new Uint8Array([21, 31, 41])],
  blockstore: new LevelBlockStore()
})

const carParts = []
for await (const part of out) {
  carParts.push(part)
}
