`multiaddr`. This small shim will enable libp2p to use other different
transports.
**Note:** This module uses [pull-streams](https://pull-stream.github.io) for all stream based interfaces.
## Example
```js
const TCP = require('libp2p-tcp')
const multiaddr = require('multiaddr')
const pull = require('pull-stream')
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')
const listener = tcp.createListener(mh1, (socket) => {
console.log('new connection opened')
pull(
pull.values(['hello']),
socket
)
})
listener.listen(mh1, function ready () {
console.log('ready')
listener.listen(() => {
console.log('listening')
const client = tcp.dial(mh1)
client.pipe(process.stdout)
client.on('end', () => {
listener.close()
})
pull(
tcp.dial(mh1),
pull.log,
pull.onEnd(() => {
tcp.close()
})
)
})
```
outputs
```
ready
connection
bye
listening
new connection opened
hello
```
