    spawn-please

    npm version

    Promisified child_process.spawn. *Supports stdin* *Rejects on stderr*

    Install

    $ npm install --save spawn-please

    Usage

    promise = spawn(command, [arguments], [stdin], [options])

    options are passed directly through to child_process.spawn.

    const spawn = require('spawn-please')
     
    spawn('printf', ['please?'])
      .then(output => {
        assert.equal(output, 'please?')
      })

    How is this different than other child_process libraries?

    • Allows you to pass a string to stdin:
    spawn('cat', [], 'test')
      .then(output => {
        assert.equal(output, 'test')
      })
     
    • Rejects on any stderr:
    spawn('some-command-with-stderr')
      .catch(stderr => {
        // do something with stderr 
      })

    Using your own Promise library

    spawn-please uses the global Promise object by default. You may use your own Promise library by overriding the Promise property:

    const spawn = require('spawn-please')
    spawn.Promise = require('bluebird')
