# webrtc-swarm
> Create a swarm of p2p connections using webrtc and a
[signalhub](https://github.com/mafintosh/signalhub).
```
npm install webrtc-swarm
```
## Usage
``` js
var swarm = require('webrtc-swarm')
var signalhub = require('signalhub')
var hub = signalhub('swarm-example', ['http://yourdomain.com'])
var sw = swarm(hub, {
wrtc: require('wrtc') // don't need this if used in the browser
})
sw.on('peer', function (peer, id) {
console.log('connected to a new peer:', id)
console.log('total peers:', sw.peers.length)
})
sw.on('disconnect', function (peer, id) {
console.log('disconnected from a peer:', id)
console.log('total peers:', sw.peers.length)
})
```
## API
```js
var swarm = require('webrtc-swarm')
```
### var sw = swarm(hub, opts)
Creates a new webrtc swarm using
[signalhub](https://github.com/mafintosh/signalhub) `hub` for discovery and
connection brokering.
Valid keys for `opts` include:
- `wrtc` - (optional) a reference to the `wrtc` library, if using Node.
- `uuid` - (optional) a unique identifier for this peer. One is generated for
you if not supplied.
- `maxPeers` - (optional) the maximum number of peers you wish to connect to.
Defaults to unlimited.
- `wrap` - (optional) a function that can modify the WebRTC signaling data
before it gets send out. It's called with `wrap(outgoingSignalingData,
destinationSignalhubChannel)` and must return the wrapped signaling data.
- `unwrap` - (optional) a function that can modify the WebRTC signaling data
before it gets processed. It's called with `unwrap(incomingData,
sourceSignalhubChannel)` and must return the raw signaling data.
Additional optional keys can be passed through to the underlying
[simple-peer](https://www.npmjs.com/package/simple-peer) instances:
- `channelConfig` - custom webrtc data channel configuration (used by
`createDataChannel`)
- `config` - custom webrtc configuration (used by `RTCPeerConnection`
constructor)
- `stream` - if video/voice is desired, pass stream returned from
`getUserMedia`
### sw.close()
Disconnect from swarm
### sw.on('peer|connect', peer, id)
`peer` and `connect` are interchangeable. Fires when a connection has been
established to a new peer `peer`, with unique id `id`.
### sw.on('disconnect', peer, id)
Fires when an existing peer connection is lost.
`peer` is a [simple-peer](https://www.npmjs.com/package/simple-peer) instance.
### sw.on('close')
Fires when all peer and signalhub connections are closed
### sw.peers
A list of peers that `sw` is currently connected to.
### swarm.WEBRTC_SUPPORT
Detect native WebRTC support in the javascript environment.
```js
var swarm = require('webrtc-swarm')
if (swarm.WEBRTC_SUPPORT) {
// webrtc support!
} else {
// fallback
}
```
