## The purpose
smartipc makes it easy to spawn tasks into subprocesses without loosing control over what those processes do.
You can transparently call functions and expect returned data using promises.

## Usage

Server:
```typescript
import {Ipcserver} from 'smartipc'
import * as q from 'q'

let myIpcserver = new Ipcserver({
    appspace: 'mymodule'
})

// The subprocess js file cannot have any cli arguments
// since this mechanism is used by IpcServer to setup the connection
myIpcServer.spawnProcess('./myFile','mySubProcessNameAlias') // nameAlias identifies the subprocess and will prefix any logs from child Process

let someData = {
    key1: 'value1',
    key2: 'value2'
}

myIpcServer.call('mySubProcessNameAlias','myAwesomeFunction',someData).then(someAnswerData => {
    console.log(someAnswerData.key1)
})

```

Client:
```
import { Ipcclient } from './smartipc'
import * as q from 'q'

let localIpc = new Ipcclient() // gets its connection information automatically using CLI args internally

let myAwesomeFunction = (dataArg) => {
    let done = plugins.q.defer()
    console.log('awesome') // this will log transparently in the same console stream as the host process
    let someAnswerData = {key1: 'this is an answer'}
    done.resolve(someAnswerData)
    return done.promise
}

localIpc.register([myAwesomeFunction])
```
