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.

Logging

Aside from logLevel configuration option you can set the level via an environment variable LOG_LEVEL, which overrides configuration.

At log levels DEBUG and TRACE module will print call source location.

Use bunyan CLI tool to pretty-print JSON logs; running the module with pretty-print enabled is not recommended.
