• send(text: string, to?: Endpoint): Promise<string>
• on(event: DataChannelEvent, handler: DataChannelEventHandlers): void

send(text, to)

Description

Sends text to a specific endpoint in the call.

Arguments

• text - The data to be sent through the data channel.
• to - Optional Endpoint that should receive the text. If not specified, text is broadcast to all endpoints in the data channel.

Example

let infobipRTC = createInfobipRtc('2e29c3a0-730a-4526-93ce-cda44556dab5', {debug: true});
infobipRTC.connect();

let roomCall = infobipRTC.joinRoom('test_room', RoomCallOptions.builder().setDataChannel(true).build());
roomCall.dataChannel()
        .send("Hello world!")
        .then(id => console.log(`Sent text with id: ${id}`));

on(event, handler)

Description

Configures the event handler for data channel events.

Arguments

• event: DataChannelEvent - Name of the data channel event. Allowed values are a subset of DataChannelEvent.

• handler: DataChannelEventHandlers - Function that will be called when specified event occurs, with exactly one parameter being passed to the function containing event information. Depending on the event, the passed parameter will contain a set of fields that will describe the event, namely:

  • TEXT_DELIVERED_EVENT - The data received in this event includes: the ID associated with the text, the date, and a boolean representing whether the text was delivered successfully or not.

    event = {id: string, date: Date, delivered: boolean}

  • TEXT_RECEIVED_EVENT - The data received in this event includes: the text, the Endpoint representing the sender, a boolean which represents whether the text is sent directly to its recipient or not, and the date.

    event = {text: string, from: Endpoint, isDirect: boolean, date: Date}

Example

let infobipRTC = createInfobipRtc('2e29c3a0-730a-4526-93ce-cda44556dab5', {debug: true});
infobipRTC.connect();

let roomCall = infobipRTC.joinRoom('test_room', RoomCallOptions.builder().setDataChannel(true).build());
let dataChannel = roomCall.dataChannel();

dataChannel.on(DataChannelEvent.TEXT_DELIVERED_EVENT, (event) => {
    let delivered = event.delivered ? "delivered" : "not delivered";
    console.log(`Text with id ${event.id} was ${delivered}.`);
})

dataChannel.on(DataChannelEvent.TEXT_RECEIVED_EVENT, (event) => {
    console.log(`Received text ${event.text} from ${event.from.identifier}.`)
});
