Support filtering on host, name and address family (IPv4 vs IPv6)

[wimleers]

First off: THANK YOU! This works great! 🚀 I'm using this in https://github.com/wimleers/homebridge-sma-home-manager.

This is what I have today:

bonjour.find({ type: 'http' }, function () {
  // custom filtering logic
});

finds the result I need:

 {
  addresses: [ '2a02:1812:1416:6f00:240:adff:feb7:e999', '192.168.0.237' ],
  subtypes: [],
  rawTxt: [ <Buffer > ],
  txt: {},
  name: 'Website for SMA-Inverter: SMA3010955555-3',
  fqdn: 'Website for SMA-Inverter: SMA3010955555-3._http._tcp.local',
  host: 'SMA3010955555-3.local',
  referer: { address: '192.168.0.237', family: 'IPv4', port: 5353, size: 177 },
  port: 443,
  type: 'http',
  protocol: 'tcp'
}

But much of that custom filtering logic could easily be done by making .find() and .findOne()'s options argument more powerful, by expanding what src/lib/utils/filter-service.ts does.

IOW:

bonjour.findOne({
  type: 'http',
  host: /SMAd+/,
  name: /^Website for SMA-Inverter .*/
  addressFamily: 'IPv4'
}, function () {
  // no filtering logic needed anymore!
});

That'd result in my getting

 {
  addresses: [ '192.168.0.237' ],
  subtypes: [],
  rawTxt: [ <Buffer > ],
  txt: {},
  name: 'Website for SMA-Inverter: SMA3010955555-3',
  fqdn: 'Website for SMA-Inverter: SMA3010955555-3._http._tcp.local',
  host: 'SMA3010955555-3.local',
  referer: { address: '192.168.0.237', family: 'IPv4', port: 5353, size: 177 },
  port: 443,
  type: 'http',
  protocol: 'tcp'
}

… with less logic needed on my end 😊

@wimleers Not a problem. To confirm, you're looking for RegExr filtering for the browser?

[wimleers]

Yes: a declarative equivalent for a callback, with each of the supported fields allowing a regex 👍
