That's more than any other country in the world. China also has the highest percentage of people using these apps, with 21.9% of their population engaging with online learning platforms.

On average, each user spends about $74.59 on these apps. This shows that people are willing to invest in their education and personal growth through digital means.

These numbers paint a clear picture: online learning apps are not just a trend; they're becoming a major part of how people learn worldwide. For anyone thinking about creating an education app, now is an exciting time to enter this rapidly expanding market.

Must-Have Features of a Great Educational App

When creating an educational app, these five features can significantly enhance the learning experience:

• Real-time virtual learning tools: Live video lessons, interactive whiteboards, and screen sharing allow teachers and students to interact in real-time. This gives users a virtual classroom experience, where they can collaborate, ask questions, and get instant feedback. Features like real-time messaging and breakout rooms also help students participate in group activities and discussions, making learning more interactive and engaging.
• Personalized learning paths: Not all users learn the same way. Hence, personalize content to each user's learning style and pace. It starts with an assessment of the user's current knowledge, then creates a custom plan. As the user progresses, the app adjusts difficulty levels to keep learning challenging but not overwhelming.
• **Interactive content: **Great educational apps use various interactive elements like quizzes, puzzles, and simulations. For language apps, this might include speech recognition. For science apps, it could be virtual experiments. These elements help users apply what they've learned, improving retention.
• Progress tracking: This feature shows users their completed lessons, quiz scores, and overall progress towards goals. It might use charts or graphs to display improvement over time. Good progress tracking also highlights areas needing more practice, helping learners stay focused and motivated.
• Offline mode: This allows users to download lessons or quizzes for use without an internet connection. It's crucial for learning on-the-go or in areas with poor connectivity. The app should sync progress when the user goes back online.

Prerequisites

Before we start, let's make sure you have everything you need:

• Sign up for a ZEGOCLOUD developer account.
• Obtain your AppID and Server URL from the ZEGOCLOUD admin dashboard.
• Have Node.js installed on your machine.
• Ensure your project is set up to use npm for dependency management.
• Basic knowledge of JavaScript or TypeScript development.
• A modern browser that supports WebRTC.
• Make sure your device is connected to the internet.

1. Create a New Project

Before integrating the video call and whiteboard functionality, you need to set up your project structure.

Create a project folder with the following structure:

project-folder/
├── index.html
├── index.js

Add HTML and JavaScript Files:

• index.html will contain the basic structure for the video call interface and the whiteboard.
• index.js will hold all the logic for initializing and managing the SDKs.

Example: This code will be used in our index.html to provide basic user interface for your educational app with video and whiteboard integration.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Video Call & Whiteboard Integration</title>
    <style>
        #video-container {
            display: flex;
            justify-content: space-between;
        }
        video {
            width: 48%;
            height: 300px;
            background-color: #000;
        }
        #whiteboard-container {
            margin-top: 20px;
            width: 100%;
            height: 500px;
            border: 2px solid #000;
        }
    </style>
</head>
<body>
    <h1>Video Call with Whiteboard</h1>
    <div id="video-container">
        <video id="localVideo" autoplay muted></video>
        <video id="remoteVideo" autoplay></video>
    </div>
    <div id="whiteboard-container"></div>

    <script src="index.js"></script>
</body>
</html>

2. Install the Required SDKs

Install the necessary SDKs for both video calls and whiteboarding features. Use npm to install the ZegoExpress and ZegoSuperBoard SDKs.

Run the following commands:

npm i zego-express-engine-webrtc
npm i zego-superboard-web

If you encounter permission errors on macOS or Linux, use sudo:

sudo npm i zego-express-engine-webrtc
sudo npm i zego-superboard-web

3. Import the SDKs

In your index.js file, import both the Zego Express Engine (for video calls) and Zego SuperBoard (for whiteboard functionality):

import { ZegoExpressEngine } from 'zego-express-engine-webrtc';
import { ZegoSuperBoardManager } from 'zego-superboard-web';

Alternatively, you can use require if you're working in a non-module environment:

const ZegoExpressEngine = require('zego-express-engine-webrtc').ZegoExpressEngine;
const ZegoSuperBoardManager = require('zego-superboard-web').ZegoSuperBoardManager;

4. Initialize the SDKs

You must initialize both the Zego Express SDK for video calls and the SuperBoard SDK for whiteboards.

4.1 Initialize the Zego Express Engine (Video)

To initialize the Zego Express Engine, create an instance by passing in your AppID and Server URL, which you can obtain from the ZEGOCLOUD Admin Console.

const appID = 123456789; // Replace with your actual AppID
const server = 'wss://your-server-url'; // Replace with your actual server URL

// Initialize the ZegoExpressEngine instance
const zg = new ZegoExpressEngine(appID, server);

4.2 Initialize the Zego SuperBoard SDK (Whiteboard)

To initialize the SuperBoard, call the getInstance method and use the init method to initialize it.

// Initialize the SuperBoard SDK
const zegoSuperBoard = ZegoSuperBoardManager.getInstance();
const result = await zegoSuperBoard.init(zg, {
    parentDomID: 'whiteboard-container', // ID of the parent container
    appID: appID, 
    userID: 'your_user_id', // Replace with your User ID
    token: 'your_token_here' // Replace with your Token
});

Ensure the Zego Express SDK is initialized before calling this initialization method.

5. Set Up Video Call Logic

To enable video calls, you need to set up the logic for local and remote streams.

const localVideo = document.getElementById('localVideo');
const remoteVideo = document.getElementById('remoteVideo');

async function startVideoCall() {
    try {
        const userID = 'user_' + new Date().getTime();
        const token = 'your_token_here'; // Replace with your token

        // Log in to the room
        await zg.loginRoom('demo-room', token, { userID, userName: userID });

        // Create and play the local video stream
        const localStream = await zg.createStream();
        localVideo.srcObject = localStream;

        // Publish the local stream
        zg.startPublishingStream('streamID', localStream);

        // Listen for remote stream updates
        zg.on('roomStreamUpdate', async (roomID, updateType, streamList) => {
            if (updateType === 'ADD') {
                const remoteStream = await zg.startPlayingStream(streamList[0].streamID);
                remoteVideo.srcObject = remoteStream;
            }
        });
    } catch (err) {
        console.error('Error starting video call:', err);
    }
}

// Start video call
startVideoCall();

6. Set Up the Whiteboard

Once the user logs into the room and video streams are active, set up the whiteboard functionality.

async function createWhiteboard() {
    try {
        const whiteboard = await zegoSuperBoard.createWhiteboardView({
            name: 'Class Whiteboard', // Whiteboard name
            perPageWidth: 1600, // Width of each page
            perPageHeight: 900, // Height of each page
            pageCount: 1 // Number of pages
        });
    } catch (err) {
        console.error('Error creating whiteboard:', err);
    }
}

// Initialize whiteboard after login
createWhiteboard();

This code creates a simple whiteboard where users can draw in real-time.

7. Handle Whiteboard Events

You can listen for events such as when the whiteboard is updated or when someone adds a new whiteboard. These callbacks will help you keep the whiteboard in sync across all participants.

zegoSuperBoard.on('remoteSuperBoardSubViewAdded', function(uniqueID) {
    console.log('A new whiteboard was added:', uniqueID);
});

zegoSuperBoard.on('remoteSuperBoardSubViewRemoved', function(uniqueID) {
    console.log('A whiteboard was removed:', uniqueID);
});

8. Log Out and Clean Up

When the session ends, make sure to log out from the room and clean up the resources by deinitializing the SDKs.

// Leave the room
zg.logoutRoom('demo-room');

// Deinitialize the whiteboard SDK
zegoSuperBoard.unInit();

// Destroy the Zego Express Engine
zg.destroyEngine();
