Object Cloning

Creates a deep clone of an object, ensuring that nested objects are also cloned rather than just copying their references.

const Hoek = require('@hapi/hoek');
const obj = { a: 1, b: { c: 2 } };
const clone = Hoek.clone(obj);

Object Merging

Merges all the properties of the source object into the target object. This is a deep merge operation.

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

Assertion

Throws an error if the condition is not true. Useful for adding assertions in your code to ensure that certain conditions are met.

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

Reach

Allows you to access a nested property within an object using a string path.

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

Apply To Defaults

Applies a set of default keys and values to an object, only adding values if they are not already present in the object.

const Hoek = require('@hapi/hoek');
const defaults = { a: 1, b: 2 };
const options = { b: 3, c: 4 };
const result = Hoek.applyToDefaults(defaults, options);
