Compatibility changes

SDK structural optimization

The SDK for ReactJS is developed based on the SDK for Web v4.x. To further enhance usability, this version incorporates all Web SDK APIs into the ReactJS SDK, eliminating the need to integrate the Web SDK separately.

Upon upgrading to this version, make the following modifications:

• Reintegrate the React SDK. Taking npm as an example:

  # Remove existing dependencies
  npm uninstall agora-rtc-react agora-rtc-sdk-ng
  # Reinstall dependencies
  npm install agora-rtc-react

• Adjust the import of the AgoraRTC interface from the Web SDK. Taking the combined import of AgoraRTC and AgoraRTCProvider as an example:

  // Before this version
  import AgoraRTC from "agora-rtc-sdk-ng";
  import { AgoraRTCProvider } from "agora-rtc-react";
  // As of this version
  import AgoraRTC, { AgoraRTCProvider } from "agora-rtc-react"

NetworkQuality renaming

To avoid redundancy with the Web SDK's API, this version makes the following changes to the ReactJS SDK's NetworkQuality interface:

• Rename NetworkQuality to NetworkQualityEx and have NetworkQualityEx inherit the NetworkQuality interface from the Web SDK.
• Rename the uplink and downlink properties to uplinkNetworkQuality and downlinkNetworkQuality, respectively.

If you use the NetworkQuality interface from the ReactJS SDK, make the necessary code modifications after upgrading to this version.

Improvements

This version adds the cameraVideoTrackConfig parameter to useLocalCameraTrack, enabling you to set video capture configurations such as capture devices and encoder when creating a camera video track.

Issues fixed

This version fixed the issue that the SDK threw the error CAN_NOT_PUBLISH_MULTIPLE_VIDEO_TRACKS in Firefox's developer mode.
