Jitsi Meet API

You can use the Jitsi Meet API to embed Jitsi Meet in to your application. You are also welcome to use it for embedding the globally distributed and highly available deployment on meet.jit.si itself. The only thing we ask for in that case is that you please DO NOT remove the jitsi.org logo from the top left corner.

Installation

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

<script src='https://meet.jit.si/external_api.js'></script>

API

api = new JitsiMeetExternalAPI(domain, options)

The next step for embedding Jitsi Meet is to create the Jitsi Meet API object. Its constructor gets a number of options:

• domain: domain used to build the conference URL, 'meet.jit.si' for example.
• options: object with properties - the optional arguments:
  • roomName: (optional) name of the room to join.
  • width: (optional) width for the iframe which will be created. If a number is specified it's treated as pixel units. If a string is specified the format is number followed by 'px', 'em', 'pt' or '%'.
  • height: (optional) height for the iframe which will be created. If a number is specified it's treated as pixel units. If a string is specified the format is number followed by 'px', 'em', 'pt' or '%'.
  • parentNode: (optional) HTML DOM Element where the iframe will be added as a child.
  • configOverwrite: (optional) JS object with overrides for options defined in config.js.
  • interfaceConfigOverwrite: (optional) JS object with overrides for options defined in interface_config.js.
  • noSSL: (optional, defaults to true) Boolean indicating if the server should be contacted using HTTP or HTTPS.
  • jwt: (optional) JWT token.
  • onload: (optional) handler for the iframe onload event.
  • invitees: (optional) Array of objects containing information about new participants that will be invited in the call.
  • devices: (optional) A map containing information about the initial devices that will be used in the call.

Example:

const domain = 'meet.jit.si';
const options = {
    roomName: 'JitsiMeetAPIExample',
    width: 700,
    height: 700,
    parentNode: document.querySelector('#meet')
};
const api = new JitsiMeetExternalAPI(domain, options);

You can set the initial media devices for the call:

const domain = 'meet.jit.si';
const options = {
    ...
    devices: {
        audioInput: '<deviceLabel>',
        audioOutput: '<deviceLabel>',
        videoInput: '<deviceLabel>'
    },
    ...
};
const api = new JitsiMeetExternalAPI(domain, options);

You can overwrite options set in config.js and interface_config.js. For example, to enable the filmstrip-only interface mode, you can use:

const options = {
    ...
    interfaceConfigOverwrite: { filmStripOnly: true },
    ...
};
const api = new JitsiMeetExternalAPI(domain, options);

You can also pass a jwt token to Jitsi Meet:

const options = {
   ...
   jwt: '<jwt_token>',
   noSsl: false,
   ...
};
const api = new JitsiMeetExternalAPI(domain, options);

Controlling the embedded Jitsi Meet Conference

Device management JitsiMeetExternalAPI methods:

• getAvailableDevices - Retrieve a list of available devices.

api.getAvailableDevices().then(devices => {
    // devices = {
    //     audioInput: [{
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'audioinput'
    //         label: 'label'
    //     },....],
    //     audioOutput: [{
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'audioOutput'
    //         label: 'label'
    //     },....],
    //     videoInput: [{
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'videoInput'
    //         label: 'label'
    //     },....]
    // }
    ...
});

• getCurrentDevices - Retrieve a list with the devices that are currently selected.

api.getCurrentDevices().then(devices => {
    // devices = {
    //     audioInput: {
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'videoInput'
    //         label: 'label'
    //     },
    //     audioOutput: {
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'videoInput'
    //         label: 'label'
    //     },
    //     videoInput: {
    //         deviceId: 'ID'
    //         groupId: 'grpID'
    //         kind: 'videoInput'
    //         label: 'label'
    //     }
    // }
    ...
});

• isDeviceChangeAvailable - Resolves with true if the device change is available and with false if not.

// The accepted deviceType values are - 'output', 'input' or undefined.
api.isDeviceChangeAvailable(deviceType).then(isDeviceChangeAvailable => {
    ...
});

• isDeviceListAvailable - Resolves with true if the device list is available and with false if not.

api.isDeviceListAvailable().then(isDeviceListAvailable => {
    ...
});

You can also add multiple event listeners by using addEventListeners. This method requires one argument of type Object. The object argument must have the names of the events as keys and the listeners of the events as values. NOTE: This method still exists but it is deprecated. JitsiMeetExternalAPI class extends EventEmitter. Use EventEmitter methods.

function incomingMessageListener(object)
{
// ...
}

function outgoingMessageListener(object)
{
// ...
}

api.addEventListeners({
    incomingMessage: incomingMessageListener,
    outgoingMessage: outgoingMessageListener
});

If you want to remove a listener you can use removeEventListener method with argument the name of the event. NOTE: This method still exists but it is deprecated. JitsiMeetExternalAPI class extends EventEmitter. Use EventEmitter methods( removeListener).

api.removeEventListener('incomingMessage');

If you want to remove more than one event you can use removeEventListeners method with an Array with the names of the events as an argument. NOTE: This method still exists but it is deprecated. JitsiMeetExternalAPI class extends EventEmitter. Use EventEmitter methods.

api.removeEventListeners([ 'incomingMessage', 'outgoingMessageListener' ]);

You can get the number of participants in the conference with the following API function:

const numberOfParticipants = api.getNumberOfParticipants();

}).catch(() => {
    // failure
});

NOTE: The format of the invitees in the array depends on the invite service used for the deployment.

You can remove the embedded Jitsi Meet Conference with the following API function:

api.dispose();

NOTE: It's a good practice to remove the conference before the page is unloaded.
