upnp-ssdp

UPnP SSDP node module implements the SSDP device discovery as specified in http://www.upnp.org/specs/arch/UPnP-arch-DeviceArchitecture-v1.0-20080424.pdf

The rough idea is for the server to listen for 'M-SEARCH' multicast messages on 239.255.255.250 (port 1900). The server responds to the client with it's location (typically an IP address and a port).

Installation

npm install upnp-ssdp

Usage

Announce your server using announce().

var Ssdp = require('upnp-ssdp');
var server = Ssdp();
server.announce('device:server');

Clients can now discover the server using search().

var Ssdp = require('upnp-ssdp');
var client = Ssdp();
client.on('up', function (address) {
    console.log('server found', address);
});
client.on('down', function (address) {
    console.log('server ' + address + ' not responding anymore');
});
client.on('error', function (err) {
    console.log('error initiating SSDP search', err);
});
client.search('device:server');
