Spaceport is a decentralized service registry for nodejs. There is no central server to maintain or register with. Processes communicate peer-to-peer over multicast (similar to zeroconf/mdns).
Spaceport works great when you have any processes that need to talk to one another but you don't want to predefine their locations or ports.
** This module only works with node 0.10+ **
npm install spaceport
To create a new service and announce its presence.
// port can be specified programmically if assigned by the system
var service = spaceport.service('service name', { port: 1234 });
// the service will now announce it is available and capable of responding to requests
service.start();
// to stop the service and announce it should not longer be available
service.stop();To listen to a particular service.
// create a browser to tell us when this service comes online
var browser = spaceport.browser('service name').start();
// service is available
browser.on('up', function(service) {
// unique identifier for the service
service.ident
// hostname of the service box (obtained with os.hostname)
service.host
// custom information for the service
// these details are passed in when the service is created
// { port: 1234 } above is the details
service.details
// the service is offline will trigger a down event
service.once('down', function() {
});
