Spawn Promise

Child Process Spawn as a Promise, with simple in/out piping

Install

npm install --only=production --save @ahmadnassri/spawn-promise

API

spawn (command [, args] [, options] [, input])

identical to child_process.spawn in every way, except:

• writes the input value to stdin,
• on success returns a Promise that is fulfilled with a simple object containing both stdin & stdout buffers.
• on failure returns a Promise rejected with a SpawnError error object containing both stdin & stdout buffers.

Usage

import Spawn from '@ahmadnassri/spawn-promise';

const options = {
  env: process.env 
}

// success
spawn('grep', ['f'], options, 'foo')
    .then(streams => console.log(streams.stdout))
