Web Real-Time Communication (WebRTC) is a collection of standards, protocols, and JavaScript APIs, the combination of which enables peer-to-peer audio, video, and data sharing between browsers (peers). Instead of relying on third-party plug-ins or proprietary software, WebRTC turns real-time communication into a standard feature that any web application can leverage via a simple JavaScript API.
Delivering rich, high-quality, RTC applications such as audio and video teleconferencing and peer-to-peer data exchange requires a lot of new functionality in the browser: audio and video processing capabilities, new application APIs, and support for half a dozen new network protocols.
There are several open source WebRTC projects. One famous project is https://github.com/muaz-khan/RTCMultiConnection
It provides variety of audio/video/text chat, screen/file sharing functionalities.
