Why JS-Get

• Fast
• Lightweight, well-documented source code bundled as CJS, EM and UMD
• 100% test coverage
• Supports objects and arrays

Installation

To install JS-Get, just run the following:

$ npm install @hypefactors/js-get

Note: This package was only tested on Node.js versions 9 and 8 or higher.

Usage

Import the module via import get from '@hypefactors/js-get' or if you're not using a bundler use require instead (Node environment).

Given that there is an object with the following structure:

const profile = {
  age: 15,
  name: {
    first: 'John'
  },
  activities: [
    'sports',
    {
      name: 'fishing',
      frequency: 'weekly'
    }
  ]
}

The properties can be accessed using dot notation:

get(profile, 'age') // 15
get(profile, 'name.first') // 'John'
get(profile, 'activities.0') // 'sports'
get(profile, 'activities.1.frequency') // 'weekly'
get(profile, 'foobar', 'not-found') // 'not-found'

Or using array syntax:

get(profile, ['age']) // 15
get(profile, ['name', 'first']) // 'John'
get(profile, ['activities', '0']) // 'sports'
get(profile, ['activities', '1', 'frequency']) // 'weekly'
get(profile, ['foobar'], 'not-found') // 'not-found'
