Usage

import { tcp } from '@libp2p/tcp'
import { multiaddr } from '@multiformats/multiaddr'
import { pipe } from 'it-pipe'
import all from 'it-all'

// A simple upgrader that just returns the MultiaddrConnection
const upgrader = {
  upgradeInbound: async maConn => maConn,
  upgradeOutbound: async maConn => maConn
}

const transport = tcp()()

const listener = transport.createListener({
  upgrader,
  handler: (socket) => {
    console.log('new connection opened')
    pipe(
      ['hello', ' ', 'World!'],
      socket
    )
  }
})

const addr = multiaddr('/ip4/127.0.0.1/tcp/9090')
await listener.listen(addr)
console.log('listening')

const socket = await transport.dial(addr, { upgrader })
const values = await pipe(
  socket,
  all
)
console.log(`Value: ${values.toString()}`)

// Close connection after reading
await listener.close()

Outputs:

listening
new connection opened
Value: hello World!
