ipfs-blob-store

An abstract-blob-store compatible implementation built using IPFS as the storage backend

Implements the abstract-blob-store, using IPFS for storage.

Install

npm install ipfs-blob-store

Usage

ipfs-blob-store uses the IPFS Files API to create the abstraction of a mutable filesystem over snapshots of Merkle DAGs (per mutation). You'll need to use the Files API directly to get the /ipfs/Qm... address of the filesystem root so that other IPFS nodes can retrieve it.

It requires an IPFS node to run - you can either specify a host/port combination to connect to a remote daemon, pass an instance of ipfs or nothing at all to have the blob store manage it's own IPFS node.

Self-managed IPFS node

const ipfsBlobStore = require('ipfs-blob-store')

const store = await ipfsBlobStore()

store.exists('/my-file.txt', (error, exists) => {
  // ...
})

Pre-configured IPFS node

const ipfsBlobStore = require('ipfs-blob-store')
const IPFS = require('ipfs')

const node = new IPFS({
  // some config here
})

node.once('ready', () => {
  const store = await ipfsBlobStore({
    ipfs: node
  })

  store.exists('/my-file.txt', (error, exists) => {
    // ...
  })
})

Remote IPFS daemon

const ipfsBlobStore = require('ipfs-blob-store')

const store = await ipfsBlobStore({
  host: '127.0.0.1',
  port: 5001
})

store.exists('/my-file.txt', (error, exists) => {
  // ...
})

Options

var options = {
  ipfs: null, // an instance of ipfs or ipfs-api
  port: 5001,   // default value
  host: '127.0.0.1', // default value
  baseDir: '/', // default value
  flush: true  // default value
}

const store = await ipfsBlobStore(options)

API

See abstract-blob-store for the blob store API.
