fetch-pkgs-info

A tool gets the package info of node modules.

Install

Install from the NPM repository using yarn or npm:

yarn add fetch-pkgs-info

npm install fetch-pkgs-info

Quick Start

Create a js file:

import GetPackageJsonProcess from 'fetch-pkgs-info'

const config = {
  modules: [
    { name: 'react', version: '16.0.0' },
    { name: 'redux', version: '4.0.0' }
  ]
}

new GetPackageJsonProcess(config).run()
  .then(result => {})
  .catch(err => {})

Or you can pass the second parameter to the constructor GetPackageJsonProcess to specify the attributes what need to be returned.

import GetPackageJsonProcess, { retrievePkgs } from 'fetch-pkgs-info'

const config = {
  modules: [
    { name: 'react', version: '16.0.0' },
    { name: 'redux', version: '4.0.0' }
  ],
  attributes: ['name', 'version', 'dependencies'],
  installPkgTool: 'npm'
}

// method 1:
new GetPackageJsonProcess(config).run()
  .then(result => {})
  .catch(err => {})

// method 2:
retrievePkgs(config)
  .then(result => {})
  .catch(err => {})
