WebRTC
WebRTC (Web Real-Time Communication) is an open-source project and set of APIs that enables real-time audio, video, and data communication directly between web browsers and mobile applications without requiring plugins or additional software. It provides peer-to-peer connectivity with built-in security and is widely used for video conferencing, voice calls, and screen sharing applications. The technology handles media capture, encoding, network traversal, and secure transmission.
Developers should learn WebRTC when building applications that require real-time communication features like video calls, live streaming, or peer-to-peer data transfer, as it eliminates the need for third-party plugins and provides native browser support. It's particularly valuable for creating telehealth platforms, remote collaboration tools, online education systems, and customer support chat with video capabilities where low-latency communication is critical.
