Node.js is a JavaScript runtime built on Chrome’s V8 engine that enables running JavaScript on the server side.
Node.js in WebRTC
Node.js is commonly used in WebRTC application stacks for:
- Signaling servers: Node.js with WebSocket libraries (ws, Socket.IO) is the most popular choice for WebRTC signaling servers due to its event-driven, non-blocking architecture
- TURN server management: Generating time-limited TURN credentials
- Room management: Handling room creation, participant tracking, and session coordination
- Recording orchestration: Coordinating server-side recording workflows
Node.js and WebRTC media
While Node.js handles signaling well, it does not natively include libWebRTC for media processing. Projects like node-webrtc and wrtc provide native bindings for server-side WebRTC in Node.js, enabling use cases like server-side recording or media processing bots.
For media-heavy server-side work, dedicated media server frameworks (mediasoup for Node.js, Janus, Pion) are preferred over raw libWebRTC bindings.
