Simple library for communicating different processes. 

I developed the library for communicating different cluster processes. It also connects different machines in the same local network to share clusters and distribute the work.

```bash

$ npm install cluster-eventbus --save

```



Sample working on a Node cluster:

```js

const numCPUs = require('os').cpus().length;

const cluster = require('cluster');

const EventBus = require('cluster-eventbus');

let eventBus = new EventBus({

    core: `MacBook Pro (914)`,

    debug: true

}).cluster(cluster);

if (cluster.isMaster) {

    for (let i = 1; i < numCPUs + 1; i++) {

        cluster.fork();

    }

} else {

    eventBus.prepareWorker(cluster, (params) => {

        

            // do something with params

            // and return something

        

            return {

                "message": `hello ${params.id}, I'm worker_${cluster.worker.id}`,

                "params_received": params

            };

        }

    );

}

```

### Ask

Ask something to a worker:

```js

let response = await eventBus.event(`MacBook Pro (914)`,`worker_1`, {

  "message": `hello worker 1`,

  "id": `test_worker`

})

```

Response model:

```json

{

    "response": {},

    "error": true,

    "error_message": ""

}

```

### Ask To All

Ask the same to all workers:

```js

let response = await eventBus.eventAll({

  "message": `hello workers`,

  "id": `test_worker`,

  "data": {

      "method": "get_name"

  }

})

```

Response model:

```json

{

    "responses": [{}, {}],

    "error": true,

    "error_messages": ["", ""]

}

```

### Close Process

Close everything by calling:

```bash

await eventBus.closeAll();

```

### Machine Name

```js

EventBus.MACHINE_NAME

```

Response:

```

MacBook Pro (914)

```
