Sample

this code initialise connection between client and server side and send an "hello world" message

var Telepathy = require('telepathymq');

// initialise the server side
// the constructor take a string argument for the instance identity
// used to send data from other node.
// it must be uniq on connected nodes.
var server = new Telepathy('server');
server.listen(8060, function() {
  console.log('server is listening on port 8060');
});
server.on('register', function(identity) {
  console.log(identity + ' has registered on server');
});
server.on('message', function(msg) {
  console.log('message: ' + msg);
});

// initialise the client side
var client = new Telepathy('client');
client.register('server', 'tcp://localhost:8060');
client.on('register', function(identity) {
  console.log(identity + ' has registered on client');
  // emit an event called 'message' on 'server' with a string 'hello world' as data
  client.emit('server', 'message', 'hello world');
});

Methods

server.listen()

Start a server listening for connections. Possible signatures:

  • listen(port, [ip,] callback)
  • listen(url, options, callback)

server.listen(port, [ip,] callback)

port: integer tcp port number ip: string ip address (optional, default: '0.0.0.0') callback: function

server.listen(connectString, [options,] callback)

connectString: string {tcp | tls}://{ip | hostname}:{port} options: object see node tls.createServer options only use in tls protocol callback: function

client.register(identity, connectString, [options,] callback)

immediately initiates connection. When the connection is established, a 'register' event will be emitted on the client.

identity: string identity of server node connectString: string {tcp | tls}://{ip | hostname}:{port} options: object see node tls.connect options only use in tls protocol callback: function

node.emit(identity, eventName, data)

emit an event on identity node.

identity: string identity of the other side node. eventName: string the name of the event being emited data: string,object data being sent over event

node.on(eventName, listener)

Adds the listener function to the end of the listeners array for the event named eventName.

eventName: string the name of the event. listener: function

node.defer(identity, eventName[, data])

return an asynk promise and send an asynk deferred.

identity: string identity of the other side node. eventName: string the name of the event being emited data: string,object data being sent over event

server.on('myDefer', function(defer, data) {
  if (data.val === 1) {
    defer.notify('some data');
  }
});

var promise = client.defer('server', 'myDefer', {val: 1});
promise.progress(function(data) {
  console.log(data);
});
