object-has-keys v0.2.3

object-has-keys

A JavaScript utility to check if given object has a set of keys.

Getting started

The first step is to add object-has-keys into your project.

$ npm install --save object-has-keys

Usage

Import the package into your package using require or import statements

const { hasKeys, hasAnyKey } = require('object-has-keys'); // CommonJS

import { hasKeys, hasAnyKey } from 'object-has-keys'; // ES2015+

The hasKeys function takes two arguments, the object and the keys. It returns true if all the keys queried exist.

const myObject = {
  key1: 'value',
  key2: 'value',
  key3: 'value'
};

hasKeys(myObject, 'key1'); // true
hasKeys(myObject, ['key1', 'key2']); // true

hasKeys(myObject, 'key5'); // false
hasKeys(myObject, ['key5']); // false
hasKeys(myObject, ['key1', 'key5']); // false

The hasAnyKey function takes two arguments, the object and the keys. It returns true if any key queried exists.

const myObject = {
  key1: 'value',
  key2: 'value',
  key3: 'value'
};

hasAnyKey(myObject, 'key1'); // true
hasAnyKey(myObject, ['key1', 'key5']); // true

hasAnyKey(myObject, 'key5'); // false
hasAnyKey(myObject, ['key6']); // false
