Hi,
Since NS7 is becoming more adopted (including in my projects), i was wondering if we could get this plugin updated for NS7.

I have had a go at this, and i can create a PR for the changes I've made. But unfortunately i haven't been able to get it to work just yet.

Hello. Thanks for the awesome module. However, it doesn't return an IP address.

Here's what Bonjour returns:

{ addresses:
   [ 'fe80::1067:1df6:2e65:440e',
     '192.168.88.235',
     'fe80::f4ae:26ff:fe41:63fd',
     'fe80::4006:72c4:f4b7:6292',
     'fe80::cd1b:e77e:f9bb:6ae6',
     'fe80::608e:f9b2:c226:272b',
     'fe80::f287:c988:48f9:c88b',
     'fe80::1daf:386d:b81:afc6',
     'fe80::aede:48ff:fe00:1122' ],
  name: 'RoomOS',
  fqdn: 'RoomOS._http._tcp.local',
  host: 'Damilola-10.local',
  referer:
   { address: '192.168.88.235',
     family: 'IPv4',
     port: 5353,
     size: 568 },
  port: 3000,
  type: 'http',
  protocol: 'tcp',
  subtypes: [],
  rawTxt: <Buffer 0e 47 72 65 65 74 69 6e 67 3d 48 45 4c 4c 4f>,
  txt: { greeting: 'HELLO' } }

Here's what the module returns:

{eventName: "propertyChange", object: Zeroconf, propertyName: "serviceFound", value: Object, oldValue: undefined}
serviceFound: {"eventName":"propertyChange","object":{"_observers":{"propertyChange":[{}]},"serviceType":"_http._tcp.","netServiceBrowser":{}},"propertyName":"serviceFound","value":{"name":"RoomOS","type":"_http._tcp.","host":"Damilola-9.local.","port":3000}}

Is there anyway with this plugin, or via other methods that i can resolve a hostname.

This plugin returns the hostname, eg. serviceFound: {"name":"FX DocuPrint M225 dw","type":"_printer._tcp.","host":"BRN3000000000.local.","port":515,"address":"{}"}'

Is there a reason for only returning the hostname, and not an IP address?

Long story short, i need an IP address, and not a hostname - it just wont work for my case. Using multiple tools, i am able to see the IP address through the mDNS/zeroconf service discovery.

I have had a look around in the plugin to get an understanding on what is going on. What is interesting is that the addresses property comes back with an empty object.

Any help would be appreciated.

I've used the example code to try and find services but nothing is returned. I'm using avahi-browse on another computer to verify that my services are in fact discoverable.

I see in the log that service discovery has started:

10-28 19:21:15.555  1456  2267 D NsdService: Discover services
10-28 19:21:15.555  1456  2267 D NsdService: mdnssd [discover, 78, _http._tcp.]
10-28 19:21:15.558  1456  2267 D NsdService: Discover 6 78_http._tcp.

Is there any code involved?

• provide a code example to recreate the problem
• (EVEN BETTER) provide a .zip with application or refer to a repository with application where the problem is reproducible.

    this.zeroconf = new Zeroconf('_http._tcp.', 'local.'); // param 1 = service type, param 2 = domain
    this.zeroconf.on(
        Observable.propertyChangeEvent, 
        (data) => {
            switch(data.propertyName.toString()) {
                case 'serviceFound': {
                  console.log(`serviceFound: ${JSON.stringify(data.value)}`);
                  break;
                }
                case 'serviceLost': {
                  console.log(`serviceLost: ${JSON.stringify(data.value)}`);
                  break;
                }
            }
        }
    );
    this.zeroconf.startServiceDiscovery();
