Spawn Promise

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

Install

npm install @ahmadnassri/spawn-promise

API

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

identical to [child_process.spawn][node-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 stdout & stderr buffers.
• on failure returns a Promise rejected with a SpawnError error object containing both stdout & stderr buffers.

Usage

const spawn = require('@ahmadnassri/spawn-promise')

const options = {
  env: process.env
}

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