WebRTC

WebRTC (Web Real-Time Communication) is an {{Glossary("API")}}  that can be used by video-chat, voice-calling, and P2P-file-sharing Web apps.

WebRTC consists mainly of these parts:

• {{domxref("MediaDevices.getUserMedia", "getUserMedia()")}} 
  • : Grants access to a device’s camera and/or microphone, and can plug in their signals to a RTC connection.
• {{domxref("RTCPeerConnection")}} 
  • : An interface to configure video chat or voice calls.
• {{domxref("RTCDataChannel")}} 
  • : Provides a method to set up a {{Glossary("P2P", "peer-to-peer")}}  data pathway between browsers.
