🇩 defu

Recursively assign default properties. Lightweight and Fast!

Install

Install package:

npm install defu

OR

yarn add defu

Usage

const options = defu (object, ...defaults)

Most left arguments have more perioriry when assigning defaults.

Arguments

• object (Object): The destination object.
• source (Object): The source object.

const defu = require('defu')

console.log(defu({ 'a': { 'b': 2 } }, { 'a': { 'b': 1, 'c': 3 } }))
// => { a: { b: 2, c: 3 } }

Remarks

• object and defaults are not modified
• null values are skipped same as defaults-deep. Please use either omit-deep or lodash.defaultsdeep if you need to to preserve.
• Assignment of __proto__ and constructor keys will be skipped to prevent security issues with object pollution.
