⛔️ DEPRECATED

As of 1.1.0 the @helia/delegated-routing-v1-http-api-client module supports both the libp2p ContentRouting and PeerRouting interfaces so should be used instead.

This library will not be maintained.

About

This is an implementation of the libp2p content routing interface that uses an IPNI HTTP endpoint.

An alternative is HTTP Routing V1 (previously known as Reframe) but the advantage of IPNI at least as of 2023-05-19 is that it returns results in a streaming fashion which can be faster. Note that this will change with the rollout of IPIP-410, at which point one can use the HTTP Routing V1 interface/implementation directly.

Example

import { createLibp2p } from 'libp2p'
import { ipniContentRouting } from '@libp2p/ipni-content-routing'

const node = await createLibp2p({
  contentRouters: [
    ipniContentRouting('https://cid.contact')
  ]
  //.. other config
})
await node.start()

for await (const provider of node.contentRouting.findProviders('cid')) {
  console.log('provider', provider)
}
