API

Event Bus

const {EventBus} = require('event-bus-mini') 

const bus = new EventBus({port: 8000, name: 'MY AWESOME BUS'})

bus.addEvent('event1', ({data, logger, client})=> {
    useData(data)
})

bus.addEvent('event2', ({data, logger, client})=> {
    useData2(data)
})

bus.addEvent('event3', ({data, logger, client})=> {
    useData3(data)
})

bus.start() // Actually start the server

Event Bus Inside Docker Container

To run the Bus inside a docker container,

1. Edit the file dockerConfig.js to specify some events that will occure on the bus
2. Build an image: docker build -t eventbus .
3. Run this command to start a container, providing a port for your server AND mapping that port to a port on the host machine: docker run -e p=9090 -p 8080:9090 eventbus

Bus Subscriber

const {BusSubscriber} = require('event-bus-mini')

let sub = new BusSubscriber({hostname: '127.0.0.1',port: 8000})

sub.addSubscription('event1', (data)=> {
    console.log('got some dataaa!', data)
})

sub.addSubscription('event2', (data)=> {
    console.log('got some other dataaa!', data)
})

sub.addSubscription('event3', (data)=> {
    console.log('got even more awesome dataaa!', data)
})

sub.subscribe() // Start listening to listed events

Bus Publisher

const {BusPublisher} = require('event-bus-mini')

const publisher = new BusPublisher({hostname: '132.11.341',port:8000})

publisher.publish({event: 'event1', data: money})

publisher.publish({event: 'event2', data: {name: 'cedric', age: 22}})

publisher.publish({event: 'event3', data: {awesomeness: 'gold'}})

PS: In order to use the library in the browser, the imports need to be changed from require('event-bus-mini') : to const BusSubscriber = require('event-bus-mini/BusSubscriber') and const BusPublisher = require('event-bus-mini/BusPublisher')
