node-ssdp

Simple Service Discovery for Node 0.12, handling Upnp NOTIFY and M-SEARCH requests.

This is pretty much a rewrite of a library I forked https://github.com/bazwilliams/node-upnp-client the fork of which stopped working when I upgraded to Node 12. I decided to pare the library right down to the parts I was using, i.e. SSDP and rewrite those portions.

Installation

npm install node-upnp-ssdp

Examples

In the examples folder there are some example applications one of which shows a simple service discovery with a preset mSearch for Openhome Devices; the other shows simple service discover if the parameter is left unset, the search request is for all devices ssdp:all.

If a device is found a DeviceFound event is emitted.

Whenever the module is first used, it starts listening for SSDP broadcasts from other devices on your network, it will announce the following events:

• DeviceAvailable - emitted when a NOTIFY message received with ssdp:alive
• DeviceUnavailable - emitted when a NOTIFY message received with ssdp:byebye
• DeviceUpdate - emitted when a NOTIFY message received with ssdp:update

In addition, the above events also emit events categorised by their notfication type. I.e. if you are only interested in Openhome playlist services with type urn:av-openhome-org:service:Playlist:1. Then add the notification type after the event name you are interested in. For example:

ssdp.on('DeviceAvailable:urn:av-openhome-org:service:Playlist:1', console.log);
