# cluster-eventdispatcher
Small and simple EventDispatcher, which executes events in **all processes**.
## Install
```
npm i --save cluster-eventdispatcher
```
## How to use
1. Create an instance of Eventdispatcher (whether in the master or in a worker):
```js
const EventDispatcher = require('cluster-eventdispatcher')
/* ... */
const dispatcher = new EventDispatcher()
```
2. Listen to events:
```js
dispatcher.on('eventname', eventdata => {
/* Do what you want*/
})
/* OR */
dispatcher.once('eventname', eventdata => {
/* Do what you want*/
})
```
3. Dispatch Events:
```js
dispatcher.dispatch('eventname', {
/* your data here */
})
```
## Documentation
Documentation is either available online at [Github Pages](chickendevlab.github.io/cluster-eventdispatcher) or can be generated using:
```
npm i
npm run doc
```
## Full Example
File is also available in the `example` directory
```js
const EventDispatcher = require('cluster-eventdispatcher')
const cluster = require('cluster')
const express = require('express')
const app = express()
if(cluster.isMaster){
const dispatcher = new EventDispatcher()
for(let i = 0; i < require('os').cpus().length; i++){
const worker = cluster.fork()
dispatcher.initWorker(worker)
}
dispatcher.on('call', data => {
console.log('/ was called: ', data)
dispatcher.dispatch('response', 'hello')
})
} else {
const dispatcher = new EventDispatcher()
dispatcher.on('response', data => console.log(data))
app.get('/', (req, res) => {
res.send('cluster-eventdispatcher example')
dispatcher.dispatch('call', {
someData: 'data'
})
})
app.listen(8080)
}
