Jitsi Meet API

You can use Jitsi Meet API to create Jitsi Meet video conferences with custom GUI.

Installation

To embed Jitsi Meet API in your application you need to add Jitsi Meet API library

<script src="https://meet.jit.si/lib-jitsi-meet.js"></script>

Now you can access Jitsi Meet API trough the JitsiMeetJS global object.

Components

Jitsi Meet API has the following components:

JitsiMeetJS
JitsiConnection
JitsiConference
JitsiTrack

Usage

JitsiMeetJS

You can access the following methods and objects trough JitsiMeetJS object.

JitsiMeetJS.init(options) - this method initialized Jitsi Meet API. The options parameter is JS object with the following properties:
1. useIPv6 - boolean property
2. desktopSharingChromeMethod - Desktop sharing method. Can be set to ‘ext’, ‘webrtc’ or false to disable.
3. desktopSharingChromeExtId - The ID of the jidesha extension for Chrome or Firefox. Example: ‘mbocklcggfhnbahlnepmldehdhpjfcjp’ desktopSharingChromeSources - Array of strings with the media sources to use when using screen sharing with the Chrome extension. Example: [‘screen’, ‘window’]
4. desktopSharingChromeMinExtVersion - Required version of Chrome extension. Example: ‘0.1’
5. desktopSharingFirefoxExtId - The ID of the jidesha extension for Firefox. If null, we assume that no extension is required.
6. desktopSharingFirefoxDisabled - Boolean. Whether desktop sharing should be disabled on Firefox. Example: false.
7. desktopSharingFirefoxMaxVersionExtRequired - The maximum version of Firefox which requires a jidesha extension. Example: if set to 41, we will require the extension for Firefox versions up to and including 41. On Firefox 42 and higher, we will run without the extension. If set to -1, an extension will be required for all versions of Firefox.
8. desktopSharingFirefoxExtensionURL - The URL to the Firefox extension for desktop sharing. “null” if no extension is required.
JitsiMeetJS.JitsiConnection - the JitsiConnection constructor. You can use that to create new server connection.
JitsiMeetJS.setLogLevel(JitsiMeetJS.logLevels.ERROR); ```
JitsiMeetJS.createLocalTracks(options) - Creates the media tracks and returns them trough Promise object.
- options - JS object with configuration options for the local media tracks. You can change the following properties there:
  1. devices - array with the devices - “desktop”, “video” and “audio” that will be passed to GUM. If that property is not set GUM will try to get all available devices.
  2. resolution - the prefered resolution for the local video.
  3. cameraDeviceId - the deviceID for the video device that is going to be used
  4. micDeviceId - the deviceID for the audio device that is going to be used
JitsiMeetJS.enumerateDevices(callback) - returns list of the available devices as a parameter to the callback function. Every device is a object with the following format:
- label - the name of the device
- kind - “audioinput” or “videoinput”
- deviceId - the id of the device.
JitsiMeetJS.isDeviceListAvailable()- returns true if retrieving the device list is support and false - otherwise.
JitsiMeetJS.isDesktopSharingEnabled() - returns true if desktop sharing is supported and false otherwise. NOTE: that method can be used after JitsiMeetJS.init(options) is completed otherwise the result will be always null.
JitsiMeetJS.events - JS object that contains all events used by the API. You will need that JS object when you try to subscribe for connection or conference events. We have two event types - connection and conference. You can access the events with the following code JitsiMeetJS.events.<event_type>.<event_name>. For example if you want to use the conference event that is fired when somebody leave conference you can use the following code - JitsiMeetJS.events.conference.USER_LEFT. We support the following events:
1. conference
  - TRACK_ADDED - stream received. (parameters - JitsiTrack)
  - TRACK_REMOVED - stream removed. (parameters - JitsiTrack)

  - KICKED - notifies that user has been kicked from the conference.
  - START_MUTED - notifies that all new participants will join with muted audio/video stream (parameters - audioMuted(boolean), videoMuted(boolean))
2. connection
  - CONNECTION_FAILED - indicates that the server connection failed.
  - CONNECTION_ESTABLISHED - indicates that we have successfully established server connection.
  - CONNECTION_DISCONNECTED - indicates that we are disconnected.
  - WRONG_STATE - indicates that the user has performed action that can’t be executed because the connection is in wrong state.
JitsiMeetJS.errors - JS object that contains all errors used by the API. You can use that object to check the reported errors from the API We have two error types - connection and conference. You can access the events with the following code JitsiMeetJS.errors.<error_type>.<error_name>. For example if you want to use the conference event that is fired when somebody leave conference you can use the following code - JitsiMeetJS.errors.conference.PASSWORD_REQUIRED. We support the following events:
1. conference
  - CONNECTION_ERROR - the connection with the conference is lost.
  - SETUP_FAILED - conference setup failed
  - AUTHENTICATION_REQUIRED - user must be authenticated to create this conference

1. TRACE
2. DEBUG
3. INFO

        attributes: {},// map with keys the name of the attribute and values - the values of the attributes.


        children: [] // array with JS object with the same structure.
    }
```
NOTE: When you use that method the passed object will be added in every system message that is sent to the other participants. It might be sent more than once.

Getting Started

The first thing you must do in order to use Jitsi Meet API is to initialize JitsiMeetJS object:

JitsiMeetJS.init();

Then you must create the connection object:

var connection = new JitsiMeetJS.JitsiConnection(null, null, options);

Now we can attach some listeners to the connection object and establish the server connection:

connection.addEventListener(JitsiMeetJS.events.connection.CONNECTION_ESTABLISHED, onConnectionSuccess);
connection.addEventListener(JitsiMeetJS.events.connection.CONNECTION_FAILED, onConnectionFailed);
connection.addEventListener(JitsiMeetJS.events.connection.CONNECTION_DISCONNECTED, disconnect);

connection.connect();

After you receive the CONNECTION_ESTABLISHED event you are to create the JitsiConference object and also you may want to attach listeners for conference events (we are going to add handlers for remote track, conference joined, etc. ):


room = connection.initJitsiConference("conference1", confOptions);
room.on(JitsiMeetJS.events.conference.TRACK_ADDED, onRemoteTrack);
room.on(JitsiMeetJS.events.conference.CONFERENCE_JOINED, onConferenceJoined);

You also may want to get your local tracks from the camera and microphone: javascript JitsiMeetJS.createLocalTracks().then(onLocalTracks);

NOTE: Adding listeners and creating local streams are not mandatory steps.

Then you are ready to create / join a conference :

room.join();

After that step you are in the conference. Now you can continue with adding some code that will handle the events and manage the conference.
