A [libp2p transport](https://libp2p.io/docs/transports-overview/) based on the TCP networking stack.

## Example

```TypeScript
import { createLibp2p } from 'libp2p'
import { tcp } from '@libp2p/tcp'
import { multiaddr } from '@multiformats/multiaddr'

const node = await createLibp2p({
  transports: [
    tcp()
  ]
})

const ma = multiaddr('/ip4/123.123.123.123/tcp/1234')

// dial a TCP connection, timing out after 10 seconds
const connection = await node.dial(ma, {
  signal: AbortSignal.timeout(10_000)
})

// use connection...
```

# Install

```console
$ npm i @libp2p/tcp
