node-ipfs-cluster-api

ipfs-cluster

A zero-dependency client to the IPFS Cluster HTTP API, built for the browser.

Install

Import it from your favourite CDN (e.g. skypack.dev, unpkg.com, jsdelivr.com) or install directly from npm:

npm i @nftstorage/ipfs-cluster

Usage

Example:

import { Cluster } from 'https://cdn.skypack.dev/@nftstorage/ipfs-cluster'

const cluster = new Cluster('https://your-cluster-domain.com')

const file = new File(['foo'], 'foo.txt')
const { cid } = await cluster.add(file)
console.log(cid) // bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu

Using in Node.js

This library is designed to run in the browser or in web workers but it can be run in Node.js if required web APIs are added to the global environment. For exmaple:

import fetch from '@web-std/fetch'
import { FormData } from '@web-std/form-data'
import { File, Blob } from '@web-std/file'

Object.assign(global, { fetch, File, Blob, FormData })

API

This library is WIP and not all cluster HTTP API methods are available yet (PR's welcome!). Please see the typescript types for full parameter and return types.

Constructor

Create a new instance of the cluster client.

import { Cluster } from '@nftstorage/ipfs-cluster'
const cluster = new Cluster('https://your-cluster-domain.com', {
  // optional custom headers for e.g. auth
  headers: { Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==' }
})

add

Import a file to the cluster. First argument must be a File or Blob.

const file = new File(['foo'], 'foo.txt')
const { cid } = await cluster.add(file)

Alternatively you can import data from a CAR (Content Addressable aRchive) file:

const car = new Blob(carFileData, { type: 'application/car' })
const { cid } = await cluster.add(car)

More information on reading and writing CAR files in JS.

addDirectory

Imports multiple files to the cluster. First argument must be an array of File or Blob.

const files = [
  new File(['foo'], 'foo.txt'),
  new File(['bar'], 'bar.txt'),
]
const dir = await cluster.addDirectory(file)

for (const entry of dir) {
  console.log(entry.cid)
  // bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu
  // bafybeidsnna57jpm2ttwaydwak25qpkxafrg4cnrjsfqipbcqxlsfobjje
}

allocation

Returns the current allocation for a given CID.

const cid = 'bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu'
const allocation = await cluster.allocation(cid)

metricNames

Get a list of metric types known to the peer.

const names = await cluster.metricNames()
console.log(names) // [ 'ping', 'freespace' ]

pin

Tracks a CID with the given replication factor and a name for human-friendliness.

const cid = 'bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu'
const { cid } = await cluster.pin(cid)

recover

Re-triggers pin or unpin IPFS operations for a CID in error state.

const cid = 'bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu'
const { cid } = await cluster.recover(cid)

status

Returns the current IPFS state for a given CID.

const cid = 'bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu'
const status = await cluster.status(cid)

for (const [clusterPeerID, pinInfo] of Object.entries(status.peerMap)) {
  console.log(`${clusterPeerID}: ${pinInfo.status}`)
  // e.g.
  // 12D3KooWAjKw14hMUo7wdyEu9KwogrUFCCMiQZApgZ4zMcvtcacj: pinned
  // 12D3KooWKiebn7GqPvjqjKARnm47Xoez6f1civBEWxef3u5G6UdM: pinned
  // 12D3KooWLKdPdFx5UpPNwoVmMXsLULCDegAqXZ7RAgpKuPSMKoSS: pinned
}

unpin

Untracks a CID from cluster.

const cid = 'bafybeigpsl667todjswabhelaxvwmk7amgg3txsv5tkcpbpj5rtrf6g7mu'
await cluster.unpin(cid)
