warning

Skip this part if you are already installed the SDK using NPM.

note

Minimum Requirement Angular version 8.3.29

Step 1: To download the files from the Angular SDKs, click on the Download button.

Download SDK Files

Download

Step 2: Extract the files from the downloaded zip file and copy them into your application.

Step 3: Create a new folder inside your project's Root folder and paste all the copied files into it.

Step 4: Once the file has been copied, include the script file into your index.html

Step 5: Open your angular.json and search for the property by navigating the buttons : build => options => scripts.

Step 6: Here, you can find the array of scripts wherein you can add the relative file paths of respective downloaded SDK JS files.

Step 7: Now, add the below codes in the Root component (before @Component Decorator).

declare var SDK: any;

Step 8: Once you have added the SDK into Root component’s ngOnInit, initialize our SDKs within angular's initialization method.

Initialize Call SDK#

caution

If you already initialized the SDK, you can add the below callback listeners to receive call related events.

To begin with the initialization process of the call SDK you are required to have certain data that responds to the changes in the connection status in the client's app.

Now, paste the license key on the licensekey param and use the below given method to pass these data through the SDK for further processing.

note

When you are in the trial mode, by default the sandbox servers will be used. After purchase it will be upgraded to dedicated server.

const incomingCallListener = (res) => {};
const callStatusListener = (res) => {};
const userTrackListener = (res) => {};
const muteStatusListener = (res) => {};
const missedCallListener = (res) => {};
const callSwitchListener = (res) => {};
const inviteUsersListener = (res) => {};
const mediaErrorListener = (res) => {};
const callSpeakingListener = (res) => {};
const callUsersUpdateListener = (res) => {};
const callUserJoinedListener = (res) => {};
const callUserLeftListener = (res) => {};
const callConnectionQualityListener = (res) => {};
const helper = {}

const initializeObj = {
  licenseKey: "XXXXXXXXXXXXXXXXX",
  callbackListeners: {
    connectionListener,
    incomingCallListener,
    callStatusListener,
    userTrackListener,
    muteStatusListener,

Request Input for registerMetaData#

Arguments	Description	Type
key	Name of the Key	String
value	Name of the value	String or Boolean or Number

caution

If FORCE_REGISTER is false and if it reached the maximum no of multiple-sessions, then registration will not success and it will throw a 405 exception. Either FORCE_REGISTER should be true or one of the existing session need to be logged out to continue registration.

note

If you want to use your own Id, you can use the userJid in the registration response.

Response Params#

Arguments	Description	Type

    username: "123456789",
    password: "987654321",
    isProfileUpdated: true,
    isSandbox: true,
    userJid: "1234567890@xmppdomain"
  }
}

caution

userJid is the unique id that allows you to connect with other users to send or receive messages.

Connect to MirrorFly Server#

Step 1: You can use the credentials that you have obtained while registration to make the connection with the server.

Step 2: Once you have created the connection successfully, you will be responded with an approval message as ‘statusCode of 200’ or else will get an execution error.

Step 3: With this you can also trace the connection status that you receive in connectionListener callback function.

Step 4: If you face any error while making a connection with the server, you will receive an error message with callback.

await SDK.connect(`USERNAME`, `PASSWORD`);

const userJid = SDK.getJid(USER_NAME)

Argument	Description	Type
USER_NAME	unique username which we get from `Register` response.	String

Make a voice call#

Initiate a call by providing the callee’s user JID into the makeVoiceCall method. Once the call initiated successfully, a callStatusListener callback will be triggered and callee user call status will be received here.

caution

If One to one call feature is unavailable for your plan, then it will throw 403 exception

SDK.makeVoiceCall(['USER_JID'], null, metadata, (success, error) => {
  if (error) {
    // Error occured while making the call
  }
  if (success) {
    // Call has been made successfully
  }
});

Request Params#

`USER_JID`	User JID	Array	true
`GROUP_ID`	Group Id - For one to one calls, provide `null`.	String	false
`metadata`	metadata - is an optional parameter to provide Metadata of call. `Maximum size is 3`. Example : {key : value}	Object	false
`callback`	Callback method to handle success and error while making the call	Method	false

note

A metadata object key and value should both be strings.

success#

{
  statusCode: 200, // Number - status code
  message: "", // String - Success/Error Message 
  callType: "", // String - Call Type - "audio"
  roomId: "" // String - Unique room ID 
}

note

To receive the user track, a userTrackListener callback should already be registered in the caller's client app. Whenever you make the call to a user, you will receive your own track and the callee's track in the same callback method. To differentiate the user, You can use the 'localUser' and 'userJid' param. You will receive both Audio and Video track in the same callback method.

Sample Javascript code to play the track#

<html>
  <audio id="audio" autoplay playsinline></audio>
  <video id="video" autoplay playsinline></video>
  <script>
    //let track = TRACK_OBJECT from the callback method
    //let element = ELEMENT_OBJECT in which you need to play the audio/video
    let stream = new MediaStream([track]);
    try {
        element.srcObject = stream;
    } catch (e) {
        try {
          element.src = URL.createObjectURL(stream);
        } catch (e) {
          console.error("Error attaching stream to element", e);
      }
  }
  </script>
</html>

You need to supply the track object which was received in the callback method to the audio/video element based on the track type that you have received.

warning

For the Audio/Video call, you shouldn't play your own Audio track.

Receive incoming call#

To receive an incoming call, a incomingCallListener callback should already be registered in the callee’s client app. Whenever a user make call to a user, the callee user will receive the calling data in this callback.

// Callback Response Argument Structure
{
    allUsers:["USER1_JID", "USER2_JID",...],
    callTime: 1681905421215,
    callType: "audio|video",
    groupId: null|GROUP_ID,
    localUser: BOOLEAN,
    roomId: "wmupbheao",
    roomLink: "ndy-bmkb-eui"
    status: "calling",
    toUsers: ["USER_JID"],
    userDetails: {},
    userJid: "FROM_USER_JID",
    usersStatus: [{}]
}

Response Params#

Arguments	Description
allUsers	JID's of the users in the call.
callTime	Call intiated time in timestamp format.
callType	Describe the audio or video call.
groupId	Contain the group ID If the call is group call. Otherwise, the value will be NULL.
localUser	To determine local user or not
roomId	Call room ID.
roomLink	Call room Link.
status	Status of the call(calling, ringing, connecting, connected).
toUsers	Array of User JID of callee users.
userDetails	User details object of the callee users.
userJid	User JID who intiated the call
usersStatus	Array of users with the details of the call.

Answer a call#

To answer a call use the answerCall method.

SDK.answerCall((success, error) => {
  if (error) {
    // Error occured while answering the call
  }
  if (success) {
    // Call has been answered successfully
  }
});

note

To receive the user track, a userTrackListener callback should already be registered in the caller's client app. Whenever you answer the call, you will receive your own track and the caller's track in the same callback method itself. To differentiate the user, You can use the 'localUser' and 'userJid' param. You will receive both Audio and Video track in the same callback method.

Sample Javascript code to play the track#

<html>
  <audio id="audio" autoplay playsinline></audio>
  <video id="video" autoplay playsinline></video>
  <script>
    //let track = TRACK_OBJECT from the callback method
    //let element = ELEMENT_OBJECT in which you need to play the audio/video
    let stream = new MediaStream([track]);
    try {
        element.srcObject = stream;
    } catch (e) {
        try {
          element.src = URL.createObjectURL(stream);
        } catch (e) {
          console.error("Error attaching stream to element", e);
      }
  }
  </script>
</html>

You need to supply the track object which was received in the callback method to the audio/video element based on the track type that you have received.

warning

For the Audio/Video call, you shouldn't play your own Audio track.

End a call#

To end a call use the endCall method.

SDK.endCall((success, error) => {
  if (error) {
    // Error occured while ending the call
  }
  if (success) {
    // Call has been ended successfully
  }
});
