libp2p-tcp

js-libp2p-tcp

Node.js implementation of the TCP module that libp2p uses, which implements the interface-connection interface for dial/listen.

Description

libp2p-tcp in Node.js is a very thin shim that adds support for dialing to a multiaddr. This small shim will enable libp2p to use other different transports.

Example

const TCP = require('libp2p-tcp')
const multiaddr = require('multiaddr')

const mh1 = multiaddr('/ip4/127.0.0.1/tcp/9090')
const mh2 = multiaddr('/ip6/::/tcp/9092')

const tcp = new Tcp()

var listener = tcp.createListener(mh1, function handler (socket) {
  console.log('connection')
  socket.end('bye')
})

var listener.listen(function ready () {
  console.log('ready')

  const client = tcp.dial(mh1)
  client.pipe(process.stdout)
  client.on('end', () => {
    tcp.close()
  })
})

outputs

ready
connection
bye

Installation

npm

> npm i libp2p-tcp

API

libp2p-tcp accepts TCP addresses both IPFS and non IPFS encapsulated addresses, i.e:

/ip4/127.0.0.1/tcp/4001 /ip4/127.0.0.1/tcp/4001/ipfs/QmHash

Both for dialing and listening.
