udpfindme

udpfindme is a client and server library for finding other services on a network. There for it uses upd4 broadcast datagrams for find services. All you have to do is to set one port number for communication.

Usage

On the server side set up the message that tells something about your service.

var Server = require('udpfindme').Server;
var server = new Server(1234);
server.setMessage({
  name: 'myservice',
  port: 9999,
  address: '127.0.0.1'
});
server.on('message',function(msg,remote){
  console.log('server',msg,remote);
})

All your clients can search the service information with:

var Client = require('udpfindme').Client;
var client = new Client(1234);
client.on('found',function(data){
  console.log(data);
});
client.discover();

If you want to find all running services on all interfaces:

var Discovery = require('udpfindme').Discovery;
var discovery = new Discovery(1234);
var serviceList = [];
discovery.on('found',function(data){
  serviceList.push(data);
});
discovery.on('timeout',function(data){
  console.log(serviceList);
});
discovery.discover();
