libp2p-exchange-rendezvous

Data Exchange component that uses other peers to exchange requests/responses

Use-Case

The use case for this exchange component is to allow exchanges between two peers that are not directly connected but share one or more rendezvous peers.

Example

'use strict'

const Exchange = require('libp2p-exchange-direct')

const exchangeA = new Exchange(swarmA)
const exchangeB = new Exchange(swarmB)
const exchangeM = new Exchange(swarmM, {enableServer: true})

exchangeA.start(() => {})
exchangeB.start(() => {})
exchangeM.start(() => {})

exchangeB.listen('example', (data, cb) => {
  return cb(null, data.reverse())
})

swarmA.dial(swarmM.peerInfo, err => {
  if (err) throw err

  swarmB.dial(swarmM.peerInfo, err => {
    if (err) throw err

    exchangeA.request(swarmB.peerInfo.id, 'example', Buffer.from('Hello World!'), console.log)
  })
})
