Utilities for nps (npm-package-scripts)

The problem

nps is a great package to empower your scripts and there are some common things you wind up doing to keep your package-scripts.js file clean, useful, and maintainable. So you wind up duplicating utility functions across projects.

This solution

This has several utility functions you'll often want when using nps.

Installation

This module is distributed via [npm][npm] which is bundled with [node][node] and should be installed as one of your project's dependencies:

npm install nps-utils

Usage

You'll most likely use this in your package-scripts.js file:

const npsUtils = require('nps-utils')

module.exports = {
  scripts: {
    validate: npsUtils.concurrentNPS('lint', 'build', 'test --coverage'),
    lint: 'eslint .',
    build: 'webpack --env.production',
    test: 'jest'
  }
}

Available methods:

Series Commands

const npsUtils = require('nps-utils')

module.exports = {
  scripts: {
    validate: npsUtils.series('nps build', 'nps lint', 'nps test'),
    lint: 'eslint .',
    build: 'webpack --env.production',
    test: 'jest'
  }
}

Rimraf Commands

const npsUtils = require('nps-utils')

module.exports = {
  scripts: {
    clean: npsUtils.rimraf('build'),
  }
}

  }
}
