Elevating Microsoft Teams: The Impact of Migrating from Electron to WebView2

INTRODUCTION
''In the rapidly evolving landscape of desktop application development, Microsoft Teams have recently made a significant shift in their underlying technology. Both applications, which were initially built on the Electron framework, have transitioned to using Microsoft’s WebView2 control. This move marks a pivotal change, offering notable improvements in performance, integration, and user experience. In this blog, we’ll explore why this migration matters and what it means for developers and users alike.

Direct Insight from Rish Tandon

In a tweet, Rish Tandon, CEO of Microsoft Teams, highlighted the significance of this transition:
"With this change, we are taking a major step in #MicrosoftTeams architecture. We are moving away from Electron to Edge WebView2. Teams will continue to remain a hybrid app but now it will be powered by #MicrosoftEdge. Also, Angular is gone. We are now 100% on WebView2."

Architecture Overview

ElectronJS Process Model:

Electron is a framework that allows you to create cross-platform desktop applications by wrapping a web application. It serves as a bridge between the web application and the desktop environment, handling interactions like showing popups or responding to device connections. While Electron manages the interface with the desktop, the core functionality of the application is implemented in JavaScript.

WebView2 Based Application Process Model:

WebView2 is a versatile control similar to a text box or button, but designed for rendering web page experiences using the Chromium engine integrated into Edge. It replaces the older WebView control, which itself replaced the Web Browser control from the Win32 era. While WebView used the original Edge (Trident) rendering engine and was limited to Windows 10, WebView2 utilizes the updated Edge engine and is compatible with a broader range of Windows platforms.

Quick Summary:

Why the Shift from Electron JS to WebView2?

Transition Reasons

Performance Improvements: WebView2 is more lightweight and faster than Electron, leading to reduced memory usage and quicker load times.
Better Integration with Windows: WebView2 integrates seamlessly with Windows, enhancing performance and user experience.
Reduced Overhead: WebView2 is less resource-intensive, avoiding the need to bundle a full Chromium browser instance, which lowers the application's footprint.
Enhanced Security: WebView2 benefits from ongoing security updates for Microsoft Edge, offering a more secure environment than Electron.

Transition Results

Performance:
Memory Usage: WebView2 significantly reduces memory consumption, leading to smoother performance.
Load Times: Faster load times and quicker response rates due to optimized rendering and reduced overhead.

User Experience:
Stability: Improved stability with fewer crashes and bugs.
User Interface: More responsive interface and smoother interactions.

Integration and Compatibility:
Windows Features: Enhanced integration with Windows features like notifications and file handling.
Application Updates: Simplified updates through Edge’s update mechanism.

Developer Impact:
Development Efficiency: Streamlined framework and better debugging tools.
Code Maintenance: Easier maintenance with standardized web content handling.

Security:
Enhanced Security: Improved protection from vulnerabilities with Edge’s security features.

What This Means for Developers and Users

개발자용:
전환 복잡성: Electron에서 WebView2로 마이그레이션하려면 애플리케이션 아키텍처를 재작업해야 합니다. 개발자는 Electron 관련 기능을 WebView2와 동등한 기능으로 대체해야 하며, 종종 웹 콘텐츠 처리 방법과 네이티브 코드와 웹 콘텐츠 간의 통신 관리 방법에 상당한 변경이 필요합니다.
새로운 기회: WebView2는 기본 Windows 기능과 통합하고 최신 웹 표준을 활용할 수 있는 새로운 가능성을 열어줍니다. 개발자는 이러한 기회를 탐색하여 애플리케이션을 더욱 강화하고 더욱 강력한 기능을 제공할 수 있습니다.

사용자의 경우:
향상된 성능: 사용자는 더 빠르고 응답성이 뛰어난 애플리케이션을 경험할 수 있습니다. 이는 복잡한 디자인 작업을 처리하는 실시간 커뮤니케이션에 의존하는 Microsoft Teams와 같은 수요가 높은 애플리케이션에 특히 유용합니다.
원활한 경험: Windows 환경에 대한 더 나은 통합을 통해 사용자는 더욱 응집력 있고 유동적인 경험을 기대할 수 있습니다. 여기에는 운영 체제와의 보다 원활한 상호 작용과 Windows 관련 기능에 대한 향상된 지원이 포함됩니다.

결론

Microsoft Teams의 Electron JS에서 WebView2로의 마이그레이션은 더 나은 성능, 통합 및 최신 웹 표준 준수를 향한 중요한 변화를 의미합니다. 이러한 변화는 사용자 경험과 보안을 향상시키기 위해 데스크톱 애플리케이션을 최적화하는 추세를 강조합니다. 기술이 발전함에 따라 더 많은 애플리케이션이 유사한 발전을 채택하여 전략적 업데이트가 혁신을 주도하고 일상적인 도구를 개선할 수 있는 방법을 보여줄 것으로 예상됩니다.
