Quick Start

Suppose you wanted to monitor the temperature of a bunch of remote gauges so things don't blow up.

A typical setup for this would be to run a monitor Node and a gauge Node.

This would look like:

// Gauges server 
var gossip = require('gossip');
// Nodes are the building block of gossip. You should run one node per process. 
// They can send and receive messages to / from a cluster of nodes. 
var node = new gossip.Node('ipc://temp-gauges');
// You can subscribe to messages you are interested in. 
// Any node can check your temperature by sending you a `check-temp` message. Yay! 
node.on('check-temp', function (message, reply) {
  var gauge = gauges[];
  // read the temperature 
  var temp = gauge.readTemp();
  // send a response back 
  var response = {
    temp: temp,
  node.reply(message, response);
// Monitor server 
var gossip = require('gossip');
var node = new gossip.Node('ipc://temp-monitor');
// Join the monitor to the gauges. This will allows the node to send messages to any nodes that are known 
// by the node you are connecting to. 
setInterval(function () {
  // check temperature 
  node.send('check-temp', { gauge: 'main' }, function (err, response) {
    if ( > 600) {
      // sound the alarm 
  }, 100);
