Integration Steps

Integrating the ZEGOCLOUD Whiteboard SDK is straightforward. Below is a step-by-step guide for Web integration using JavaScript (similar steps apply for other platforms).

Prerequisites

Before starting, ensure you have:

A ZEGOCLOUD account with access to the Admin Console.
AppID and ServerSecret from the ZEGOCLOUD Admin Console.
A development environment with Node.js installed (for Web projects).
A compatible browser (e.g., latest Google Chrome) with SSL support (HTTPS, localhost, or 127.0.0.1).

Step-by-Step Integration

Set Up Your Project:
- Create a new project in your preferred framework (e.g., React, Vue, Angular, or plain JavaScript).
- Install the ZEGOCLOUD Whiteboard SDK via NPM:
```
 npm install @zegocloud/zego-uikit-prebuilt
```

Ensure your project runs on an HTTPS server or localhost.

Generate a Kit Token:

Use your AppID and ServerSecret to generate a token for authentication. Implement this on your server or use ZEGOCLOUD’s token generator.
Example (JavaScript):

 import { ZegoUIKitPrebuilt } from '@zegocloud/zego-uikit-prebuilt';

 function randomID(len) {
   let result = '';
   const chars = '12345qwertyuiopasdfgh67890jklmnbvcxzMNBVCZXASDQWERTYHGFUIOLKJP';
   for (let i = 0; i < len; i++) {
     result += chars.charAt(Math.floor(Math.random() * chars.length));
   }
   return result;
 }

 const appID = YOUR_APP_ID; // Replace with your AppID
 const serverSecret = 'YOUR_SERVER_SECRET'; // Replace with your ServerSecret
 const roomID = randomID(5);
 const kitToken = ZegoUIKitPrebuilt.generateKitTokenForTest(appID, serverSecret, roomID, randomID(5), 'UserName');

Initialize the Whiteboard:

Create a whiteboard instance using the token and attach it to a DOM element.
Example (React):

 import * as React from 'react';
 import { ZegoUIKitPrebuilt } from '@zegocloud/zego-uikit-prebuilt';

 export default function App() {
   const roomID = randomID(5);
   let myMeeting = async (element) => {
     const appID = YOUR_APP_ID;
     const serverSecret = 'YOUR_SERVER_SECRET';
     const kitToken = ZegoUIKitPrebuilt.generateKitTokenForTest(appID, serverSecret, roomID, randomID(5), 'UserName');
     const zp = ZegoUIKitPrebuilt.create(kitToken);
     zp.joinRoom({
       container: element,
       scenario: {
         mode: ZegoUIKitPrebuilt.GroupCall,
       },
       whiteboardConfig: {
         showAddImageButton: true,
         showCreateAndCloseButton: true,
       },
     });
   };

   return <div ref={myMeeting} style={{ width: '100vw', height: '100vh' }} />;
 }

Customize Whiteboard Features:

Configure settings like drawing tools and file uploads via the whiteboardConfig object.
Example:

 whiteboardConfig: {
   showAddImageButton: true,
   showCreateAndCloseButton: true,
   tools: ['pen', 'line', 'rectangle', 'text'],
 }

Test and Deploy:
- Test locally to ensure the whiteboard functions as expected.
- Deploy to an HTTPS server for production, as the SDK requires a secure connection.
- For production, generate tokens on your server instead of using generateKitTokenForTest.

Sample Code

Here’s a simplified React example for integrating the Whiteboard SDK:

import * as React from 'react';
import { ZegoUIKitPrebuilt } from '@zegocloud/zego-uikit-prebuilt';

function randomID(len) {
  let result = '';
  const chars = '12345qwertyuiopasdfgh67890jklmnbvcxzMNBVCZXASDQWERTYHGFUIOLKJP';
  for (let i = 0; i < len; i++) {
    result += chars.charAt(Math.floor(Math.random() * chars.length));
  }
  return result;
}

export default function App() {
  const roomID = randomID(5);
  let myMeeting = async (element) => {
    const appID = YOUR_APP_ID; // Replace with your AppID
    const serverSecret = 'YOUR_SERVER_SECRET'; // Replace with your ServerSecret
    const kitToken = ZegoUIKitPrebuilt.generateKitTokenForTest(appID, serverSecret, roomID, randomID(5), 'UserName');
    const zp = ZegoUIKitPrebuilt.create(kitToken);
    zp.joinRoom({
      container: element,
      scenario: {
        mode: ZegoUIKitPrebuilt.GroupCall,
      },
      whiteboardConfig: {
        showAddImageButton: true,
        showCreateAndCloseButton: true,
      },
    });
  };

  return <div ref={myMeeting} style={{ width: '100vw', height: '100vh' }} />;
}

Best Practices

Optimize for Weak Networks: Use ZEGOCLOUD’s network adaptation for smooth performance in low-bandwidth scenarios.
Test Across Devices: Ensure compatibility across Web, Android, iOS, and other platforms.
Secure Token Generation: Generate tokens on your server for production to enhance security.
Use the Admin Console: Monitor usage and manage AppID/ServerSecret via the ZEGOCLOUD Admin Console.
Leverage Documentation: Refer to the ZEGOCLOUD Developer Center for guides and API references.
