Technical Details
From a technical perspective, modern web frameworks benefit from widgets built as standalone Web Components. By wrapping the video UI in a Shadow DOM, the widget ensures zero CSS collision with your host framework, whether it's React, Next.js, or Vue. The underlying media transmission relies on WebRTC, offering low-latency peer-to-peer connections optimized for modern browsers.
