hoek

What is hoek?

The hoek package is a utility library that offers a variety of functions for object manipulation, array manipulation, type checking, and encoding. It is designed to provide developers with tools to simplify common tasks in JavaScript programming.

What are hoek's main functionalities?

Object cloning

This feature allows for deep cloning of objects, ensuring that nested objects are cloned properly rather than just copying references.

const hoek = require('hoek');
const obj = { a: 1 };
const clone = hoek.clone(obj);

Merge objects

Merge two objects into one, where the second object's properties are added to the first object. This is useful for combining configurations or settings.

const hoek = require('hoek');
const target = { a: 1 };
const source = { b: 2 };
hoek.merge(target, source);

Assert

Provides a simple assertion utility to validate conditions. If the condition is false, it throws an error with the provided message.

const hoek = require('hoek');
hoek.assert(1 === 1, 'This will not throw');
hoek.assert(1 === 2, 'This will throw an error');

Reach

Allows for safely reaching into an object for a nested property. This helps in avoiding errors when accessing deeply nested properties.

const hoek = require('hoek');
const obj = { a: { b: { c: 1 } } };
const value = hoek.reach(obj, 'a.b.c');

Other packages similar to hoek

lodash

Lodash is a comprehensive utility library offering a wide range of functions for tasks including object manipulation, array manipulation, string manipulation, and more. It is more extensive than hoek but can be bulkier due to its size.

underscore

Underscore is another utility library similar to lodash but with a smaller footprint. It provides many of the same functionalities as hoek but lacks some of the more specialized functions found in hoek.

ramda

Ramda focuses on functional programming, offering utilities that make it easier to apply functional paradigms in JavaScript. It provides similar functionalities for object and array manipulation but from a functional programming perspective, which is different from hoek's more general utility approach.

README

Utility methods for the hapi ecosystem. This module is not intended to solve every problem for everyone, but rather as a central place to store hapi-specific methods. If you're looking for a general purpose utility module, check out lodash or underscore.
