Enhance Your Video Conferences with Custom User Attributes: A Step-by-Step Guide to Agora SDK in React

Welcome to the world of interactive video conferences! With Agora SDK, you can create immersive experiences for your users. But, have you ever wondered how to take it to the next level by adding custom user attributes like names and avatars? Look no further! In this comprehensive guide, we’ll show you how to integrate user attributes into your video conferences using Agora SDK in React.

Why User Attributes Matter

Custom user attributes are essential for creating engaging video conferences. By displaying names and avatars, you can:

• Enhance user recognition and engagement
• Foster a sense of community and belonging
• Provide a more personalized experience for your users

Prerequisites

Before we dive into the implementation, make sure you have:

• Agora SDK account and project setup
• React installed in your project
• Basic knowledge of React and JavaScript

Step 1: Set up Your Agora SDK Project

First, create a new Agora SDK project or use an existing one. Make sure you have the App ID, App Certificate, and Channel Name ready.

import { createClient } from 'agora-rtc-react';

const appId = 'YOUR_APP_ID';
const appCertificate = 'YOUR_APP_CERTIFICATE';
const channelName = 'YOUR_CHANNEL_NAME';

const client = createClient({
  mode: 'rtc',
  codec: 'vp8',
});

client.init(appId, appCertificate);

Step 2: Initialize the RtcEngine

Next, initialize the RtcEngine instance, which is responsible for managing the video conference.

import { RtcEngine } from 'agora-rtc-react';

const engine = new RtcEngine(client);

Step 3: Create a User Attribute Manager

To manage user attributes, create a separate manager that will handle the attribute updates.

class UserAttributeManager {
  constructor() {
    this.attributes = {};
  }

  async getUserAttributes(userId) {
    // Implement logic to fetch user attributes from your database or storage
    const attributes = await fetchUserAttributesFromDatabase(userId);
    this.attributes[userId] = attributes;
    return attributes;
  }

  async updateAttribute(userId, key, value) {
    // Update the user attribute in your database or storage
    await updateUserAttributeInDatabase(userId, key, value);
    this.attributes[userId][key] = value;
  }
}

const userManager = new UserAttributeManager();

Step 4: Add User Attributes to the RtcEngine

Now, let’s add the user attribute manager to the RtcEngine instance.

engine.setUserAttributeManager(userManager);

Step 5: Update User Attributes

When a user joins the channel, update their attributes using the `updateAttribute` method.

engine.on('user-joined', (userId) => {
  userManager.updateAttribute(userId, 'name', 'John Doe');
  userManager.updateAttribute(userId, 'avatar', 'https://example.com/avatar.jpg');
});

Step 6: Display User Attributes in the Video Conference

Finally, display the user attributes in the video conference by accessing the `attributes` object.

function renderVideoConference() {
  return (
    <div>
      {engine.getLocalUser().video ? (
        <video></video>
      ) : (
        <img src={userManager.attributes[engine.getLocalUser().uid].avatar} alt="Avatar" />
      )}
      <p>{userManager.attributes[engine.getLocalUser().uid].name}</p>
    </div>
  );
}
