How to Build an Angular Video Chat App in 2026

Summarize this article in:

I’ve built over 9+ video calling apps in different programming languages. Of all, building in Angular seemed to offer cross-platform benefits truly better. In this guide, I’ve created a simple tutorial explaining how to build a video calling app in Angular in 13 easy steps.

Steps To Build A Video Calling App: TL;DR

To develop an app with video calling capabilities in Angular. In this guide we will use MirrorFly’s Angular video calling solution.

Get SDK license key: Obtain the credentials for MirrorFly Angular SDK
Add NPM package: Install the Angular video SDK package
Integrate call SDK: Add the video calling features to your Angular app
Initialize call SDK: Configure and initialize the SDK
Register User: Add a user with the SDK
Connect to MirrorFly server: Connect the SDK with the server
Prepare user JID: Format the user’s JID
Make a voice call: Start audio call
Make a video call: Start video call
Receive incoming call: Listen for incoming call events
Answer a call: Accept and join the call
End a call: Disconnect the active call
Decline a call: Reject the incoming call

What You’ll Need To Build The App

To build an Angular app, you will need the following:

Supported browser versions:
- Edge: 13+

Pre-built video call solution

Why Angular for Video Calls?

Angular is capable of handling multi-user streams without falling into callback loops, by natively integrating RxJS.
In a group call setting with multiple participants, Angular’s feature ‘Signal’ takes care of updating only the specific user’s tile UI who mutes, speaks, or disconnects.
Angular uses XSS scripting and HTML sanitization to prevent injection of malicious code into video tile overlays and text-chat payloads.
It’s easy to maintain the server integrations and WebRTC media setups in Angular.

How To Create A Video Chat App In Angular (Complete Guide)

The ideal process to create a fully functional chat app is to begin with MVP development. You’ll focus only on building the basics first, test it out and then move ahead with developing other parts of the platform as per your business needs.

Step 1: Get SDK license key

Contact MirrorFly’s sales team
Get a MirrorFly developer account
Login to your account
Navigate to the ‘Application Info’ section
Get the license key

Step 2: Add NPM package

Install the MirrorFly Angular video chat SDK


npm i mirrorfly-sdk

Inside your chat app, choose where you want to import the SDK and import it.

import * as SDK from "mirrorfly-sdk";

Step 3: Integrate Angular Call SDK

Go to your MirrorFly account dashboard, and click on the Download button or use the Angular video SDK package.

Download

Extract the files from the ZIP folder, and import them into the app’s root folder.
After copying the file, include the script file into the index.html
Open angular.json. Navigate the buttons build > options > scripts and then search the property. This is where you will find the array of scripts.
Here, add the relative file paths of respective downloaded SDK JS files.
Now, add the @ Component before the Decorator in the Root component.

declare var SDK: any;

After adding the SDK into Root component’s ngOnInit, initialize the Angular SDK within the angular’s initialization method.

Step 4: Initialize call SDK

For the SDK initialization process to start, you will need the client app’s connection status data.
Use the below method, and add the license key in the licensekey param to process the initialization further.

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,
    missedCallListener,
    callSwitchListener,
    inviteUsersListener,
    mediaErrorListener,
    callSpeakingListener,
    callUsersUpdateListener,
    callUserJoinedListener,
    callUserLeftListener,
    callConnectionQualityListener,
    helper
  },
};

await SDK.initializeSDK(initializeObj);

Step 5: Register User

Use the below method to register a new user to the application.
After registering, you will have a username and password. Use these credentials in the connect method to start the connection with the server.

await SDK.register(`USER_IDENTIFIER`);

Step 6: Connect to MirrorFly server

After establishing the server connection, you will receive an approval message as ‘statusCode of 200’ if successful. Otherwise, the SDK will return an execution error.
Use the connectionListener callback function to trace the status of the connection.

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

Step 7: Prepare user JID

Use the below code to generate a JID for any user:

const userJid = SDK.getJid(USER_NAME)

Step 8: Make a voice call

To start a call, use the callee’s user JID in the makeVoiceCall method. As the call starts, the SDK triggers a callStatusListener callback. This will listen to the status of the call connection.

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

Step 9: Make a video call

Now, to make a video call, use the callee’s user JID into the makeVideoCall method. Similar to the above step, the callStatusListener callback will track the status of the video call connection.

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

Step 10: Receive incoming call

Now to start receiving incoming calls, the callee’s client app will need an incomingCallListener callback. In this callback, the callee user will receive the data related to the call whenever an user makes a call to another user.

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

Step 11: Answer a call

Use the answerCall method to answer the call.

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

Step 12: End a call

To end ongoing calls, use the endCall method.

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

Step 13: Decline a call

To decline the call, use the declineCall method.

SDK.declineCall((success, error) => {
  if (error) {
    // Error occured while declining the call
  }
  if (success) {
    // Call has been declined successfully
  }
});
