Extendr

Utilities for cloning, extending, and de-referencing objects in shallow, deep, and safe ways

Install

Backend

1. Install Node.js
2. npm install --save extendr

Frontend

1. See Browserify

Usage

Example

// Shallow Clone
(function(){
	var a = {a:1}, b = {b:2}
	var c = require('extendr').clone(a,b)
	console.log(a) // {a:1}
	console.log(b) // {b:2}
	console.log(c) // {a:1,b:2}
})()

// Shallow Extend
(function(){
	var a = {a:1}, b = {b:2}
	var c = require('extendr').extend(a,b)
	console.log(a) // {a:1,b:2}
	console.log(b) // {b:2}
	console.log(c) // {a:1,b:2}
})()

Methods

• clone(args...) - shallow extend the arguments into a new object, same as extend({},args...)
• deepClone(args...) - deep extend the arguments into a new object, same as deepExtend({},args...)
• dereference(obj) - return a copy of the object with all references destroyed, same as serializing then deserializing the object
• extend(args...) - alias for shallowExtendPlainObjects
• deepExtend(args...) - alias for deepExtendPlainObjects
• shallowExtendPlainObjects(target, args...) - shallow extend the arguments into the target
• deepExtendPlainObjects(target, args...) - deep extend the arguments into the target
• safeShallowExtendPlainObjects(target, objs...) - shallow extend defined values from the arguments into the target
• safeDeepExtendPlainObjects(target, args...) - deep extend defined values from the arguments into the target

Explanation

• Use the clone methods when you don't want to modify your first object
• Use the extend methods when you want to modify the first argument
• Use the dereference method when you want to make sure that nothing has any references to the old object
• Use the safe methods when you don't want null and undefined values to overwrite a defined values
