## Installation
```sh
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
```javascript
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
```javascript
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.
