Spacebro automagically links apps between them. It binds them based on events. It is here to help you connect your apps together. You 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

$ npm i --save spacebro

You can install globally by using :

$ 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

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

You can use the bin :

spacebro --port 8888

or spacebro --port 8888 --servicename woowoo

By default the service name is spacebro

This is useful if you want to use the spacebro-client

Develop

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