STUN (Session Traversal Utilities for NAT) is a simple protocol. A STUN implementation should be simple too.

ministun is a zero dependency STUN server for Node.js. It implements "Basic Server Behavior" as defined by section 13 of RFC 5389, including backwards compatibility with RFC 3489.

Node.js >= 12.14.0

npm i ministun 

const Ministun = require("ministun"); const config = { udp4: true, udp6: true, port: 3478, log: console.log, err: console.err, sw: true }; const server = new Ministun(config); async function startServer() { await server.start(); } async function stopServer() { await server.stop(); }

• udp4: bool (Default: true)
  Support UDP over IPv4?

• udp6: bool (Default: true)
  Support UDP over IPv6?

• port: number (Default: 3478)
  Port number

• log: function || null (Default: console.log)
  Log messages will be passed to this function as arg 0, null = no message logging

• err: function || null (Default: console.err)
  Error messages will be passed to this function as arg 0, null = no error logging

• sw: bool (Default: true)
  Send the SOFTWARE attribute with response messages?
