A simple WebRTC wrapper for establishing video, voice, and data channels between browsers and Node.js.
Simple-peer is a JavaScript library that simplifies WebRTC peer-to-peer connections for video, voice, and data channels. It abstracts the complexity of WebRTC signaling and negotiation, allowing developers to establish direct browser-to-browser or browser-to-Node.js communication with minimal code. It solves the problem of implementing real-time, low-latency media and data exchange without relying on heavy frameworks.
Developers building real-time communication features like video chat, file sharing, or collaborative tools that require direct peer connections. It's ideal for those who want a lightweight, unopinionated WebRTC wrapper without the overhead of larger SDKs.
Developers choose simple-peer for its dead-simple API, cross-platform compatibility (browser and Node.js), and flexibility. Unlike heavier WebRTC libraries, it offers a minimal, stream-based interface that's easy to integrate while still supporting advanced features like trickle ICE and dynamic stream management.

Uses a familiar stream-based interface that simplifies WebRTC operations, as shown in data channel examples where peers communicate like Node.js duplex streams.
Works identically in browsers and Node.js with the wrtc package, enabling consistent development for both client and server environments, per the README's node usage guide.
Supports audio/video streams and binary data channels with easy methods like addStream and send, allowing dynamic media management without complex configuration.
Exposes low-level options such as trickle ICE and SDP transforms, giving developers fine-grained control over connection parameters for specialized use cases.
Leaves signaling entirely to the developer, requiring custom websocket or server code to exchange offer/answer data, which adds significant upfront complexity.
For multi-peer connections, it recommends a full-mesh topology that becomes impractical with many peers, as admitted in the documentation with warnings about exponential growth.
Requires the 'wrtc' package for WebRTC support in Node.js, which can be a setup hurdle and adds maintenance overhead for server-side implementations.
