Instantiating Audio Service

AloAudio Instantiation Properties

In order to instantiate the AloAudio object you are required to provide a number of properties. See Class Instantiation Properties.

AloAudio Class

Once you have defined the properties you instantiate as shown:

JavaScript

const aloAudio = new AloAudio(props);

Connection Events

Once instantiated, and connected to a channel, the user will be connected to the AloAudio Service. There are a number of event fire that are related to this connection:

Event	Description
onConnectionChange	As the connection to the Audio Service is established events showing the following statuses will be dispatched: AloAudio.CONNECTION_STATUS_ACQUIRING_ACCESS, AloAudio.CONNECTION_STATUS_CONNECTING, AloAudio.CONNECTION_STATUS_CONNECTED, AloAudio.STATUS_NOT_CONNECTED, AloAudio.CONNECTION_STATUS_ERROR, AloAudio.CONNECTION_STATUS_CONNECTED, AloAudio.CONNECTION_STATUS_RECONNECT_PENDING.
onDisconnect	Once disconnected, either intentionally or due to an error, the onDisconnect event will be dispatched.

After you instantiate AloAudio you can add event listeners for the events mentioned above.

Sample Instantiation with Event Listeners:

JavaScript

function connectToAudio() {
    const user = new VideoUser (
      "12345",
      {        
        name: "James Jones",
        deviceId: "abcd-efsg-wqer-qewe"
      }
    );
    
    const props = {   
      userAuthToken: "token generated from Authentication Service",   
      ttsEnabled: true
    };
    aloAudio = new AloAudio(props);
    initializeEventListeners();
}

function initializeEventListeners() {
    aloAudio.events.addEventListener('onDisconnect', e => {
      console.log("onDisconnect:", e.detail);
    })

    aloAudio.events.addEventListener('onConnectionChange', action(e => {
      console.log("onConnectionChange:", e.detail);

      switch (e.detail.state) {
        case AloAudio.CONNECTION_STATUS_CONNECTED:
          console.log("Ālo audio connected");
          break;
        case AloAudio.CONNECTION_STATUS_DISCONNECTED:
          console.log("Ālo audio disconnected");
          break;
        case AloAudio.CONNECTION_STATUS_ERROR:
          console.log("Ālo audio connection error", e.detail);
          break;
        case AloAudio.CONNECTION_STATUS_CONNECTING:
          console.log("Ālo audio connecting");
          break;
        case AloAudio.CONNECTION_STATUS_RECONNECT_PENDING:
          console.log("Ālo audio reconnect pending.  Retrying in ", e.detail.pendingRestartSeconds);
          break;
      }

    }));
}
