@aofl/object-utils

A small collection of Object utility functions designed to have a small footprint (20b gz) and be performant.

Api Documentation

Why?

Libraries like Lodash have a high overhead and come with more functionality than most projects need. Also, with es6 features fewer of these "utility" functions are needed.

In Lodash's case, even if you only import the needed features you still get the 4kb gzipped Core build + additional functionality.

---

Installation

npm i -S @aofl/object-utils

---

Usage

import {deepAssign} from '@aofl/object-utils';

deepAssign(leftSource, 'nested.path.to.assign', rightSource);

---

Methods

deepAssign

Recursively calls Object.assign along the specified path.

Arguments

Name	Type	Description
leftSource	Object	Left source
path	String	Path to target
rightSource	Object	Right source

Example

const user = {
  name: 'Alan',
  account: {
    active: true,
    products: {
      1: true,
      2: true,
      3: true
    }
  },
  preferences: {
   locale: 'en-US'
 }
};

const user2 = deepAssign(user, 'account.products', {
  2: false
});

// { // new ref
//   name: 'Alan',
//   account: { // new ref
//     active: true,
//     products: { // new ref
//       1: true,
//       2: false, // updated value
//       3: true
//     }
//   },
//   preferences: { // same ref
//     locale: 'en-US'
//   }
// };

console.log(user2 === user); // expected result: false
console.log(user2.account === user.account); // expected result: false
console.log(user2.preferences === user.preferences); // expected result: true

deepFreeze

Recursively calls Object.freeze on objects properties.

Note: this method should only be used in development environments and disabled in production

Arguments

Name	Type	Description

Example

let user = deepFreeze({
  name: 'Alan',
  account: {
    active: true,
    products: {
      1: true,
      2: true,
      3: true
    }
  },
  preferences: {
   locale: 'en-US'
 }
});

user.account.active = false; // Throws an error in strict mode
console.log(user.account.active); // expected output: true
