Giggle library, implementation of XEP-0166 (Jingle). XMPP audio/video chat in your Web browser!
To be used with JSJaC from Stefan Strigler, available there: sstrigler/JSJaC
Giggle is pluggable to other third-party XMPP libraries, please refer to ./src/giggle.plug.js. We'll happily accept your Pull Requests (PR).
🇫🇷 Crafted in Brest, France.
Only Giggle.js raw sources are provided in this repository. Those are not usable out-of-the-box for production purposes. You first need to build the library components on your local machine.
Important: our automated build system requires that you have NodeJS, NPM, GruntJS, Bower (+ bower-installer) and Java on your machine. UNIX systems (MacOS, Linux) are recommended to proceed build.
If you already have NodeJS and NPM installed, you can simply install GruntJS and Bower:
npm install -g grunt-cli bower bower-installer
Deploy the library in one simple command:
./tools/deploy.sh
Please first clone Giggle on your local environment, and access it over your local HTTP server. Serving example pages over HTTP is a requirement for WebRTC to work.
You can try Giggle.js one-to-one calls using the page: giggle/examples/single_client.html
Open it on 2 separate tabs or 2 different computers, and login with 2 different XMPP accounts. Then, paste the full JID of the other connected account in the call field.
The call should then be initiated, and after a while the video will come.
You can try Giggle.js multiparty calls using the page: giggle/examples/muji_client.html
Open it on 3+ separate tabs or 3+ different computers, and login with 3+ different XMPP accounts. Then, join the same conference room (you can enter any room even if it doesn't exist, on any open MUC server).
The multiparty conference call should take some time to initiate.
Note: depending on how powerful your CPU is and how much bandwidth your network can allocated, performances may degrade with many participants.
Jingle could have been implemented in a dirty-way there, so that "It just works". But it's NOT the case. Giggle.js has been thought as secure on its basis.
We wanted to avoid such possible security exploits: imagine a friend of you wants to disturb your call, and send you a session-terminate with a wrong SID. In a quick-and-dirty implementation, the request would have been dropped because the call is already ongoing, but the client-side handlers would still have been fired, thus modifying the UI.
Giggle.js simply DOES NOT fire the custom event handlers that you may have defined, so that you don't have to check yourself that each incoming packet is safe, thus to ensure your client implementation of Jingle is rock-solid (safe: session is authorized AND stanza sender is authorized AND the Jingle session flow is respected).
Multiparty call can be password-protected, in a completely transparent fashion. Giggle.js can handle the password generation process, and then transmit it to other potential call participants through the Muji call invites you send to them.
The API documentation is available in: ./doc/. You must first build Giggle to view it, please refer to the upper section about building Giggle.
We assume your XMPP Web client is using a supported XMPP library and has an active connection, stored in the GIGGLE_CONNECTION global object.
/*
* Giggle.js Implementation Example
*/
// 1. Ensure you are loading the following libraries:
// > jQuery
// > JSJaC (or any other supported XMPP library)
// > Giggle.js
// 2. Define configuration generators
var single_config_generator = function() {
// Return single configuration object
// Refer to single_client.js source for more
return {};
};
var muji_config_generator = function() {
// Return muji configuration object
// Refer to muji_client.js source for more
return {};
};
// 3. Initiate the listener
// Note: here using 'JSJaCConsoleLogger' from JSJaC as a console wrapper
Giggle.listen({
plug: GIGGLE_PLUG_JSJAC,
connection: GIGGLE_CONNECTION,
debug: (new JSJaCConsoleLogger(4)),
// Receive a one-to-one (Single) call
single_initiate: function(stanza) {
var config = single_config_generator();
// Configuration values
config.to = stanza.from() || null;
config.local_view = $('#video_local')[0];
config.remote_view = $('#video_remote')[0];
// Handle call request
session = Giggle.session(GIGGLE_SESSION_SINGLE, config);
session.handle(stanza);
},
// Receive a multiparty (Muji) call
muji_invite: function(stanza, args) {
// Note: auto-accepting call there
// you should ask the user before accepting like this
var config = muji_config_generator();
// Session values
config.to = args.jid;
config.media = (args.media == GIGGLE_MEDIA_VIDEO) ? GIGGLE_MEDIA_VIDEO : GIGGLE_MEDIA_AUDIO;
config.local_view = $('#video_local')[0];
if(args.password) {
config.password = args.password;
}
// Handle conference invite
session = Giggle.session(GIGGLE_SESSION_MUJI, config);
session.join();
}
});
// 4. Configure our disco#info handler to reply with Giggle.js features
var handle_disco_info = function(iq) {
// Do the parse work there...
// Get my client feature map
var client_map = [ /* Features here... */ ];
// Get the Giggle.js feature map
var Giggle_map = Giggle.disco();
// Concatenate feature maps
var final_map = client_map.concat(Giggle_map);
// Ensure uniqueness of feature map values there...
// Send back your response stanza there...

Here's a sum up on how to use the Giggle/Single API:
/*
* Giggle.Single.js API Example
*/
// Single call launcher
var launch_single_call = function(to, target) {
var config = single_config_generator();
// Session values
config.to = to;
config.media = (target == 'call_audio') ? GIGGLE_MEDIA_AUDIO : GIGGLE_MEDIA_VIDEO;
config.video_source = (target == 'call_screen') ? GIGGLE_VIDEO_SOURCE_SCREEN : GIGGLE_VIDEO_SOURCE_CAMERA;
config.local_view = $('#video_local')[0];
config.remote_view = $('#video_remote')[0];
// Send call request
session = Giggle.session(GIGGLE_SESSION_SINGLE, config);
session.initiate();
};
// Attach form submit event
$('form#launch_single_call').submit(function() {
var to = $(this).find('input[name="to"]').val();
var target = ($(this).find('input[name="target"]').val() || 'call_video');
if(to && target) {
// Launch call...
var session = launch_single_call(to, target);
// Send session info (client ringing & more)...
session.info(GIGGLE_SESSION_INFO_RINGING);
// Mute/Unmute audio in call...
session.mute(GIGGLE_MEDIA_AUDIO);
session.umute(GIGGLE_MEDIA_AUDIO);
// Terminate call...
session.terminate(GIGGLE_REASON_SUCCESS);
}
return false;
});The multiparty demo client source code can be found at the following URL: giggle/examples/muji_client.html
Here's a sum up on how to use the Giggle/Muji API:
/*
* Giggle.Muji.js API Example
*/
// Muji call launcher
var launch_muji_call = function(room, target) {
var config = muji_config_generator();
// Session values
config.to = room;
config.media = (target == 'call_audio') ? GIGGLE_MEDIA_AUDIO : GIGGLE_MEDIA_VIDEO;
config.video_source = GIGGLE_VIDEO_SOURCE_CAMERA;
config.local_view = $('#video_local')[0];
// Join conference room
session = Giggle.session(GIGGLE_SESSION_MUJI, config);
session.join();
return session;
};
// Attach form submit event
$('form#launch_muji_call').submit(function() {
var room = $(this).find('input[name="room"]').val();
var target = ($(this).find('input[name="target"]').val() || 'call_video');
if(room && target) {
// Launch conference...
var session = launch_muji_call(room, target);
// Send a message to conference...
session.send_message('Hello World!');
// Mute/Unmute audio in conference...
session.mute(GIGGLE_MEDIA_AUDIO);
session.umute(GIGGLE_MEDIA_AUDIO);
// Invite people to conference...
session.invite([
'[email protected]/Phone',
'[email protected]/Tablet'
]);
// Leave conference...
session.leave();
}
return false;
});We worked hard on that lib, we would appreciate your feedback and bug reports. Plus, if you are using it in your project, we would be glad if you let @valeriansaliou know.
