Introduction to RTCDataChannel

WebRTC is famous for enabling real-time audio and video calls. But did you know it can do much more?

The RTCDataChannel API lets you send any kind of data directly between browsers, creating a versatile and powerful communication link beyond just media.

While media streams are a core part of WebRTC, many real-time applications also need to share other types of data.

Think about things like chat messages, game states, file transfers, or even custom control signals. RTCDataChannel provides this capability, acting as a secure, general-purpose data pipeline.
