nt-backend-wrtc

Rendezvous + WebSocket signaling backend for WebRTC.

Note: Currently everything is under heavy development and in a very early alpha stage. APIs are thus unstable and can change without notice.

A simple rendezvous + WebSocket signaling backend for WebRTC, designed for NoisyTransfer-style workflows. It mints short‑lived numeric codes for pairing and relays SDP/ICE between two peers over WebSockets.

Features

• Rendezvous service: short‑lived numerical 4‑digit codes, single‑use redeem, reclaimed on expiry.
• WebSocket signaling for SDP/ICE exchange between two sides (A/B).
• Mailbox frames: lightweight message queue (hello, send, delivered) in addition to offer/answer/ice; optional telemetry events.
• Rate limiting (per‑IP, fixed window) for HTTP and WS upgrades.
• Observability: Prometheus /metrics, /healthz (liveness), /readyz (readiness).
• TLS: optional, with sensible defaults.
• Janitor: background sweeper that prunes expired codes.
