cross-spawn-promise v0.10.2

cross-spawn-promise

Promisified cross-spawn.

Usage

import spawn from 'cross-spawn-promise'

const command = 'ls'
const args = ['-al', '/etc']
const options = {}
spawn(command, args, options)
  .then((stdout) => {
    console.info('Success!')
    console.info('stdout:', stdout.toString())
  })
  .catch((error) => {
    console.error('Failed!')
    console.error('exit status:', error.exitStatus)
    console.error('stderr:', error.stderr.toString())
  })

API

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

The returned Promise will resolve to the process's standard output. Depending on the value of the encoding option (see below), it will either be a Buffer or a string.

The promise also exposes the created child process via its childProcess property.

Upon rejection, the following properties provide additional information on the Error object:

• exitSignal
• exitStatus
• stdout
• stderr

Options

All options are passed on to cross-spawn, with the exception of the additional encoding option. If you pass a string (e.g., 'utf8'), it will be used as the default character encoding.
