RTCPeerConnection: Direct Browser-to-Browser Links
Think of an RTCPeerConnection as a direct phone line between two browsers. It's the core of WebRTC, enabling peer-to-peer video and data streams. The footgun: it doesn't find peers; you must use a separate signaling server to broker the initial handshake.
An RTCPeerConnection is like a direct, private phone line established between two browsers, bypassing central servers for media streaming. It's the foundational API for WebRTC, used in video chat and P2P file sharing. It manages the entire lifecycle: negotiating, maintaining, and closing the connection. The common footgun is assuming it handles discovery; you must implement a separate "signaling" server to help peers exchange the initial connection metadata needed to establish the direct link.
