Spacebro

In reference to Spacebrew by Rockwell Lab (http://www.rockwellgroup.com/search/LAB)

Spacebro automagically links apps between them. It binds them based on events. You just define a list of events and make sure your client apps emits and listen to them.

It follow a centralized model where each apps automagically connects thru zeroconf and socket.io to the Spacebro server. Then each of them register a supplementary list of events.

Prerequisites

Space bro use:

• mdns to allow your app to connect seamlessly
• socket.io to broadcast events
• cli-table to display a list of connected clients
• lodash to easily handle array manipulation

Linux

$ sudo apt-get install avahi-daemon avahi-discover libnss-mdns libavahi-compat-libdnssd-dev curl build-essential

Install Spacebro to use it as a module

$ npm i --save spacebro

You can also install globally if you want to run the bin instead of developping your own app:

$ npm i -g --save spacebro

Configure

Spacebro is awaiting a config file that looks like :

{
  "server": {
    "port": 8888,
    "serviceName": "spacebro"
  },
  "events": ["event-1", "event-2", "event-3"]
}

The port define where Spacebro (socket.io) will listen. The serviceName is the name that Spacebro will use over Zeroconf. The events array allows you to define a list of events that you want to register.

Usage as a Module

const config = require('../config.json')
var spacebro = require('spacebro')
spacebro.init(config)

Usage as an app

You just run the bin :

spacebro or spacebro --port 8888 or spacebro --port 8888 --servicename woowoo

By default the service name is spacebro and the port number is 8888

This is useful if you want to use the spacebro-client as is. The spacebro client allow to connect your node application to spacebro server, just by requiring it. See Spacebro Client on github to learn more.

Develop

You can test sending events with the dev/send-events.js script. Run npm run send-events.
