## Description ## Description
`libp2p-tcp` in Node.js is a very thin shim that adds support for dialing to a `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.
`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 ## Example
```js ```js
const TCP = require('libp2p-tcp') const TCP = require('libp2p-tcp')
const multiaddr = require('multiaddr') const multiaddr = require('multiaddr')
const pull = require('pull-stream')
const mh1 = multiaddr('/ip4/127.0.0.1/tcp/9090') const mh1 = multiaddr('/ip4/127.0.0.1/tcp/9090')
const mh2 = multiaddr('/ip6/::/tcp/9092') const mh2 = multiaddr('/ip6/::/tcp/9092')
const tcp = new TCP() const tcp = new TCP()
var listener = tcp.createListener(mh1, function handler (socket) { const listener = tcp.createListener(mh1, (socket) => {
console.log('connection') console.log('new connection opened')
socket.end('bye') pull(
pull.values(['hello']),
socket
)
}) })
listener.listen(mh1, function ready () { listener.listen(() => {
console.log('ready') console.log('listening')
const client = tcp.dial(mh1) pull(
client.pipe(process.stdout) tcp.dial(mh1),
client.on('end', () => { pull.log,
listener.close() pull.onEnd(() => {
tcp.close()
}) })
)
}) })
``` ```
outputs outputs
``` ```
ready listening
connection new connection opened
bye hello
``` ```

## This module uses `pull-streams`
We expose a streaming interface based on `pull-streams`, rather then on the Node.js core streams implementation (aka Node.js streams). `pull-streams` offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about what took us to make this migration, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).
You can learn more about pull-streams at:
- [The history of Node.js streams, nodebp April 2014](https://www.youtube.com/watch?v=g5ewQEuXjsQ)
- [The history of streams, 2016](http://dominictarr.com/post/145135293917/history-of-streams)
- [pull-streams, the simple streaming primitive](http://dominictarr.com/post/149248845122/pull-streams-pull-streams-are-a-very-simple)
- [pull-streams documentation](https://pull-stream.github.io/)
### Converting `pull-streams` to Node.js Streams
If you are a Node.js streams user, you can convert a pull-stream to Node.js Stream using the module `pull-stream-to-stream`, giving you an instance of a Node.js stream that is linked to the pull-stream. Example:
```
const pullToStream = require('pull-stream-to-stream')
const nodeStreamInstance = pullToStream(pullStreamInstance)
// nodeStreamInstance is an instance of a Node.js Stream
```
