@edenware/ssdp

A fork of node-ssdp with stability improvements. A node.js SSDP client and server library.

Installation

npm install @edenware/ssdp

This is a maintained fork of the original node-ssdp package. Make sure to install @edenware/ssdp for the latest stable version with bug fixes.

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
• 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 @edenware/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.

Fork Improvements

This fork includes critical stability fixes from node-ssdp v4.0.1 applied to the v3.3.0 codebase:

• Socket availability validation: Throws clear error when no network sockets are available
• Promise-based server startup: Proper Promise handling in server.start()
• Enhanced logging: Better interface discovery logging
• Code cleanup: Removed unused coverage-related code
• Dual module compatibility: Support for both CommonJS and ES Modules

Compatibility

This fork maintains 100% API compatibility with the original node-ssdp package. Existing code will work without changes.

Module System Support

This package supports both CommonJS and ES Module (ESM) systems:

CommonJS (require):

const { Client, Server } = require('@edenware/ssdp');

ES Modules (import):

import { Client, Server } from '@edenware/ssdp';

The package automatically provides the appropriate format based on how it's imported.
