peerConnectionConfig
- Set this to specify your own STUN and TURN servers. By
default, SimpleWebRTC uses Google's public STUN server
(stun.l.google.com:19302
), which is intended for public use according to:
https://twitter.com/HenrikJoreteg/status/354105684591251456
Note that you will most likely also need to run your own TURN servers. See http://www.html5rocks.com/en/tutorials/webrtc/infrastructure/ for a basic tutorial.
Sending files between individual participants is supported. See http://simplewebrtc.com/filetransfer.html for a demo.
Note that this is not file sharing between a group which requires a completely different approach.
Sometimes you need to do more advanced stuff. See http://simplewebrtc.com/notsosimple.html for some examples.

new SimpleWebRTC(options)
object options
- options object provided to constructor consisting of:string url
- required url for signaling server. Defaults to signaling server URL which can be used for development. You must use your own signaling server for production.object socketio
- optional object to be passed as options to the signaling server connection.Connection connection
- optional connection object for signaling. SeeConnection
below. Defaults to a new SocketIoConnectionbool debug
- optional flag to set the instance to debug mode[string|DomElement] locaVidelEl
- ID or Element to contain the local video element[string|DomElement] remoteVideosEl
- ID or Element to contain the remote video elementsbool autoRequestMedia
- optional(=false) option to automatically request user media. Usetrue
to request automatically, orfalse
to request media later withstartLocalVideo
bool enableDataChannels
optional(=true) option to enable/disable data channels (used for volume levels or direct messaging)bool autoRemoveVideos
- optional(=true) option to automatically remove video elements when streams are stopped.bool adjustPeerVolume
- optional(=false) option to reduce peer volume when the local participant is speakingnumber peerVolumeWhenSpeaking
- optional(=.0.25) value used in conjunction withadjustPeerVolume
. Uses values between 0 and 1.object media
- media options to be passed togetUserMedia
. Defaults to{ video: true, audio: true }
. Valid configurations described on MDN with official spec at w3c.object receiveMedia
- optional RTCPeerConnection options. Defaults to{ offerToReceiveAudio: 1, offerToReceiveVideo: 1 }
.object localVideo
- optional options for attaching the local video stream to the page. Defaults to
{ autoplay: true, // automatically play the video stream on the page mirror: true, // flip the local video to mirror mode (for UX) muted: true // mute local video stream to prevent echo }
object logger
- optional alternate logger for the instance; any object that implementslog
,warn
, anderror
methods.
capabilities
- the
webrtcSupport
object that
describes browser capabilities, for convenience
config
- the configuration options extended from options passed to the
constructor
connection
- the socket (or alternate) signaling connection
webrtc
- the underlying WebRTC session manager
To set up event listeners, use the SimpleWebRTC instance created with the constructor. Example:
var webrtc = new SimpleWebRTC(options);
webrtc.on('connectionReady', function (sessionId) {
})
'connectionReady', sessionId
- emitted when the signaling connection emits the
connect
event, with the unique id for the session.
'createdPeer', peer
- emitted three times:
-
when joining a room with existing peers, once for each peer
-
when a new peer joins a joined room
-
when sharing screen, once for each peer
-
peer
- the object representing the peer and underlying peer connection
'stunservers', [...args]
- emitted when the signaling connection emits the
same event
'turnservers', [...args]
- emitted when the signaling connection emits the
same event
'localScreenAdded', el
- emitted after triggering the start of screen sharing
el
the element that contains the local screen stream
leftRoom, roomName
- emitted after successfully leaving the current room,
ending all peers, and stopping the local screen stream
videoAdded, videoEl, peer
- emitted when a peer stream is added
videoEl
- the video element associated with the stream that was addedpeer
- the peer associated with the stream that was added
videoRemoved, videoEl, peer
- emitted when a peer stream is removed
videoEl
- the video element associated with the stream that was removedpeer
- the peer associated with the stream that was removed
leaveRoom()
- leaves the currently joined room and stops local screen share
disconnect()
- calls disconnect
on the signaling connection and deletes it
shareScreen(callback)
- initiates screen capture request to browser, then
adds the stream to the conference
getLocalScreen()
- returns the local screen stream
stopScreenShare()
- stops the screen share stream and removes it from the room
testReadiness()
- tests that the connection is ready and that (if media is
enabled) streams have started
createRoom(name, callback)
- emits the create
event on the connection with
name
and (if provided) invokes callback
on response
joinRoom(name, callback)
- joins the conference in room name
. Callback is
invoked with callback(err, roomDescription)
where roomDescription
is yielded
by the connection on the join
event. See signalmaster for more details.
startLocalVideo()
- starts the local media with the media
options provided
in the config passed to the constructor
stopLocalVideo()
- stops all local media streams
setVolumeForAll(volume)
- used to set the volume level for all peers
volume
- the volume level, between 0 and 1
handlePeerStreamAdded(peer)
- used internally to attach media stream to the
DOM and perform other setup
handlePeerStreamRemoved(peer)
- used internally to remove the video container
from the DOM and emit videoRemoved
getDomId(peer)
- used internally to get the DOM id associated with a peer
getEl(idOrEl)
- helper used internally to get an element where idOrEl
is
either an element, or an id of an element
getLocalVideoContainer()
- used internally to get the container that will hold
the local video element
getRemoteVideoContainer()
- used internally to get the container that holds
the remote video elements
By default, SimpleWebRTC uses a socket.io connection to communicate with the signaling server. However, you can provide an alternate connection object to use. All that your alternate connection need provide are four methods:
on(ev, fn)
- A method to invokefn
when eventev
is triggeredemit()
- A method to send/emit arbitrary arguments on the connectiongetSessionId()
- A method to get a unique session Id for the connectiondisconnect()
- A method to disconnect the connection
