@helia/http

A lightweight implementation of IPFS over HTTP in JavaScript

About

Exports a createHeliaHTTP function that returns an object that implements a lightweight version of the Helia API that functions only over HTTP.

By default, content and peer routing are requests are resolved using the Delegated HTTP Routing API and blocks are fetched from Trustless Gateways.

Pass it to other modules like @helia/unixfs to fetch files from the distributed web.

Example

import { createHeliaHTTP } from '@helia/http'
import { unixfs } from '@helia/unixfs'
import { CID } from 'multiformats/cid'

const helia = await createHeliaHTTP()

const fs = unixfs(helia)
fs.cat(CID.parse('bafyFoo'))

Example - with custom gateways and delegated routing endpoints

import { createHeliaHTTP } from '@helia/http'
import { trustlessGateway } from '@helia/block-brokers'
import { delegatedHTTPRouting, httpGatewayRouting } from '@helia/routers'
import { unixfs } from '@helia/unixfs'
import { CID } from 'multiformats/cid'

const helia = await createHeliaHTTP({
  blockBrokers: [
    trustlessGateway()
  ],
  routers: [
    delegatedHTTPRouting('https://delegated-ipfs.dev'),
    httpGatewayRouting({
      gateways: ['https://cloudflare-ipfs.com', 'https://ipfs.io']
    })
  ]
})

const fs = unixfs(helia)
fs.cat(CID.parse('bafyFoo'))

Install
