Usage

import { get, set, has, clone, merge } from '@nixat/nexus';

// Get a nested property safely
const user = { profile: { name: 'John', address: { city: 'New York' } } };
const city = get(user, 'profile.address.city'); // 'New York'
const country = get(user, 'profile.address.country', 'USA'); // 'USA' (default value)

// Set a nested property safely
set(user, 'profile.address.zipCode', '10001');
// user is now { profile: { name: 'John', address: { city: 'New York', zipCode: '10001' } } }

// Check if a property exists
const hasCity = has(user, 'profile.address.city'); // true
const hasCountry = has(user, 'profile.address.country'); // false

// Clone an object
const userCopy = clone(user);

// Merge objects
const defaults = { theme: 'light', notifications: true };
const userSettings = { theme: 'dark' };
const settings = merge(defaults, userSettings);
// settings is { theme: 'dark', notifications: true }

API

Object Access

• get(obj, path, defaultValue) - Gets the value at path of object
• set(obj, path, value) - Sets the value at path of object
• has(obj, path) - Checks if path is a direct property of object

Object Manipulation

• clone(value) - Creates a deep clone of value
• merge(...objects) - Recursively merges objects
• pick(obj, paths) - Creates an object with picked object properties
• omit(obj, paths) - Creates an object without specified properties

Object Transformation

• mapKeys(obj, mapper) - Creates an object with the same values and mapped keys
• mapValues(obj, mapper) - Creates an object with the same keys and mapped values

Namespace

All functions are also available through the nexus namespace:

import { nexus } from '@nixat/nexus';

const value = nexus.get(obj, 'path.to.prop');
nexus.set(obj, 'path.to.prop', 'value');
