node-ssdp

Installation

npm install node-ssdp

There is another package called ssdp which is the original unmaintained version. Make sure to install node-ssdp instead.

Usage - Client

    var Client = require('node-ssdp').Client
      , client = new Client();

    client.on('response', function (headers, statusCode, rinfo) {
      console.log('Got a response to an m-search.');
    });

    // search for a service type
    client.search('urn:schemas-upnp-org:service:ContentDirectory:1');

    // Or get a list of all services on the network

    client.search('ssdp:all');

Usage - Server

    var Server = require('node-ssdp').Server
      , server = new Server()
    ;

    server.addUSN('upnp:rootdevice');
    server.addUSN('urn:schemas-upnp-org:device:MediaServer:1');
    server.addUSN('urn:schemas-upnp-org:service:ContentDirectory:1');
    server.addUSN('urn:schemas-upnp-org:service:ConnectionManager:1');

    server.on('advertise-alive', function (headers) {
      // Expire old devices from your cache.
      // Register advertising device somewhere (as designated in http headers heads)
    });

    server.on('advertise-bye', function (headers) {
      // Remove specified device from cache.
    });

    // start the server
    server.start();

    process.on('exit', function(){
      server.stop() // advertise shutting down and stop listening
    })

Take a look at example directory as well to see examples or client and server.

Configuration

Client

const Client = require('node-ssdp').Client
const client = new Client({...})

• interfaces String[] List of interfaces to explicitly bind. By default, bind to all available interfaces.
• explicitSocketBind Boolean Bind sockets to each discovered interface explicitly instead of relying on the system. Might help with issues with multiple NICs.
• customLogger Function A logger function to use instead of the default. The first argument to the function can contain a format string.
• reuseAddr Boolean When true socket.bind() will reuse the address, even if another process has already bound a socket on it. Default: true

Server

const Server = require('node-ssdp').Server
const server = new Server({...})

• location String URL pointing to description of your service, or a function which returns that URL
• location Object For cases where there are multiple network interfaces or IP of the host isn't known in advance, it's possible to specify location as an object. Host will be set to the IP of the responding interface.
  • location.protocol String Location protocol, defaults to http://
  • location.port Number Location port. No default.
  • location.path String Location path. No default.
• udn String Unique Device Name. Default: uuid:f40c2981-7329-40b7-8b04-27f187aecfb5.
• allowWildcards Boolean Accept wildcards (*) in serviceTypes of M-SEARCH packets, e.g. usn:Belkin:device:**. Default: false
• interfaces String[] List of interfaces to explicitly bind. By default, bind to all available interfaces.
• explicitSocketBind Boolean Bind sockets to each discovered interface explicitly instead of relying on the system. Might help with issues with multiple NICs.
• customLogger Function A logger function to use instead of the default. The first argument to the function can contain a format string.
• suppressRootDeviceAdvertisements Boolean When true the SSDP server will not advertise the root device (i.e. the bare UDN). In some scenarios this advertisement is not needed. Default: false
• reuseAddr Boolean When true socket.bind() will reuse the address, even if another process has already bound a socket on it. Default: true
• adInterval Number advertise event frequency (ms). Default: 10 sec.
• ttl Number Packet TTL. Default: 1800.

SSDP configuration:

• ssdpSig String SSDP signature. Default: node.js/NODE_VERSION UPnP/1.1 node-ssdp/PACKAGE_VERSION
• ssdpIp String SSDP multicast group. Default: 239.255.255.250.
• ssdpPort Number SSDP port. Default: 1900
• ssdpTtl Number Multicast TTL. Default: 4

Logging

You can enable logging via an environment variable DEBUG. Set DEBUG=node-ssdp:* to enable all logs. To enable only client or server logs, use DEBUG=node-ssdp:client or DEBUG=node-ssdp:server respectively.

Alternatively, you can provide your own customLogger function, in which case the DEBUG environment variable will be ignored.
