JSPM – mdns-discovery@0.2.6

Package Exports

mdns-discovery

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mdns-discovery) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

###mdns Multicast DNS

####Some Examples:

Find all Amazon Fire TV devices on the local network:

var Mdns = require('mdns-discovery');

var mdns = new Mdns({
    timeout: 4,
    returnOnFirstFound: true,
    name: '_amzn-wplay._tcp.local',
    find: 'amzn.dmgr:'
});
mdns.run (function(res) {
    res.forEach(enry) {
       console.log(entry);
    }
});

List all mdns questions and answers for 10 seconds:

var Mdns = require('mdns-discovery');

var mdns = new Mdns({ timeout: 10 });
mdns.on('packet', function (packets, rinfo) {
    if (packets.answers) packets.answers.forEach(function(packet, i) {
        console.log(`A: ${rinfo.address} - packet[${i}]=${packet.name}, type=${packet.type}, class=${packet.class}, ttl=${packet.ttl}}`);
    });
    if (packets.questions) packets.questions.forEach(function(packet, i) {
        console.log(`Q: ${rinfo.address} - packet[${i}]=${packet.name}, type=${packet.type}, class=${packet.class}, ttl=${packet.ttl}}`);
    });
});
mdns.run ();

Presence:

var mdns = require('mdns-discovery')();

mdns.onIP('192.168.1.31', function (packet, rinfo) {
    if (packet.answers.length) {
        console.log(rinfo.address + ' is present');
    }
}).run ();

Filter:

var mdns = require('mdns-discovery')();

var mdns = Mdns({
    timeout: 3,
    name: '_amzn-wplay._tcp.local',
    find: 'amzn.dmgr:'
});

var allreadyUsed = [ {ip: '192.168.1.94'}, {ip: '192.168.1.91'} ];

mdns.setFilter('ip', allreadyUsed).run (function(res) {
    res.forEach(function(v) {
        console.log(v);
    });
});
