PeerServer is a signaling server for WebRTC peer-to-peer connections established through PeerJS clients.
PeerServer solves the problem of coordinating initial connections between PeerJS clients by acting as a signaling intermediary. It does not proxy data between peers; instead, it facilitates the exchange of connection metadata needed for clients to establish direct peer-to-peer links. The server accepts configuration for port, connection key, path routing, SSL certificates, and connection limits. It can run standalone via CLI, be embedded in an existing Node.js server, or be deployed in Docker or Kubernetes environments.
Developers should choose this tool if they are building applications that use PeerJS for WebRTC communication and need to host their own signaling infrastructure rather than relying on a public server. It suits projects requiring control over connection routing, custom client ID generation, or deployment behind reverse proxies. The tool supports HTTPS, CORS configuration, and connection timeouts to handle broken or stale connections. It also offers an optional peer discovery API that exposes connected client IDs via HTTP GET.
The project maintains active engagement with its codebase through regular updates and responsiveness to issues. Development activity shows consistent attention to bug fixes and feature requests from users. The maintainers demonstrate commitment to supporting multiple deployment patterns, from simple CLI usage to complex infrastructure scenarios involving reverse proxies and Kubernetes orchestration.
