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
-
[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;
};
