@nodeutils/defaults-deep

defaults-deep

An individual component of the [nodeutils package]

Similar to lodash's defaultsDeep, but without mutating the source object, and no merging of arrays.

Installation

Install the package via npm:

$ npm install @nodeutils/defaults-deep --save

Usage

Arguments

1. [sources] (...Object): The source objects. Provide 2 or more, in descending order of importance

Returns

(Object): Returns the merged objects

Example

var defaultsDeep = require('@nodeutils/defaults-deep');

var objectA = { bar: { biz: { net: 'txi', qox: 'fuc' } }, qux: ['baz'] };
var objectB = { bar: { biz: { net: 'qux'} }, qux: ['biz', 'ban'] };
var objectC = { bar: { biz: { net: 'qux', lee: 'sox' } }, qux: ['biz', 'rep'], foo: 'bar' };

defaultsDeep(objectA, objectB, objectC);
// => { bar: { biz: { net: 'qux', qox: 'fuc', lee: 'sox' } }, qux: ['baz'], foo: 'bar' }

###How Incredibly simple:

"use strict";
const _ = require("lodash");
module.exports = function () {
    let output = {};
    _.toArray(arguments).reverse().forEach(item=> {
        _.mergeWith(output, item, (objectValue, sourceValue) => {
            return _.isArray(sourceValue) ? sourceValue : undefined;
        });
    });
    return output;
};
