Simple Peer
simple-peer is a JavaScript library that provides a wrapper for WebRTC to simplify the establishment of peer-to-peer networking in the browser. It serves as a tool for creating direct device-to-device connections for the transmission of binary data and real-time media streaming.
The library manages the exchange of strings and binary buffers through a data channel implementation and provides tools for sharing real-time audio and video tracks between peers.
It covers the full lifecycle of peer connectivity, including signaling coordination, session description negotiation, and the gathering of network addresses for NAT traversal. It also includes utilities for media track management and environment support detection.
