nested-obj is a simple and lightweight JavaScript utility library for safely accessing and modifying nested properties in objects using string paths.

Features

• Has: Check if a specific path exists within an object.

Installation

Usage

Get

Retrieve a nested property value from an object.

import objectPath from 'nested-obj';

const obj = {
  user: {
    name: 'John Doe',
    address: {
      street: '123 Main St',
      city: 'Anytown'
    }
  }
};

const userName = objectPath.get(obj, 'user.name');
console.log(userName); // 'John Doe'

Set

Set a value at a specific path in an object. If any part of the path does not exist, it will be created.

objectPath.set(obj, 'user.address.zip', '12345');
console.log(obj.user.address.zip); // '12345'
