# `Membrane.WebRTC.PhoenixSignaling.Socket`
[🔗](https://github.com/membraneframework/membrane_webrtc_plugin/blob/v0.26.7/lib/membrane_webrtc/phoenix_signaling/socket.ex#L2)

Phoenix Socket implementation which redirects all topics to a
Phoenix Channel capable of processing WebRTC signaling messages.

*Note:* This module will be available in your code only if you add `:phoenix`
to the dependencies of of your root project.

To use PhoenixSignaling, you need to:
1. Create Socket in your application endpoint, for instance:
```
  socket "/signaling", Membrane.WebRTC.PhoenixSignaling.Socket,
  websocket: true,
  longpoll: false
```
2. Create a Phoenix signaling channel with desired signaling ID and use it as `Membrane.WebRTC.Signaling.t()`
for `Membrane.WebRTC.Source`, `Membrane.WebRTC.Sink` or [`Boombox`](https://github.com/membraneframework/boombox):
```
signaling = Membrane.WebRTC.PhoenixSignaling.new("<signaling_id>")

# use it with Membrane.WebRTC.Source:
child(:webrtc_source, %Membrane.WebRTC.Source{signaling: signaling})
|> ...

# or with Membrane.WebRTC.Sink:
...
|> child(:webrtc_sink, %Membrane.WebRTC.Sink{signaling: signaling})

# or with Boombox:
Boombox.run(
  input: {:webrtc, signaling},
  output: ...
)
```
2. Create signaling channel with desired signaling ID:
```
  signaling = PhoenixSignaling.new("signaling_id")
```
3. Use the Phoenix Socket to exchange WebRTC signaling data:
```
let socket = new Socket("/singaling", {params: {token: window.userToken}})
socket.connect()
let channel = socket.channel('signaling_id')
channel.join()
  .receive("ok", resp => { console.log("Joined successfully", resp)
    // here you can exchange WebRTC data
  })
  .receive("error", resp => { console.log("Unable to join", resp) })

```
