# extend() for Node.js <sup>[![Version Badge][npm-version-png]][npm-url]</sup>
|
||
|
|
|
||
|
|
`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
* Since Node.js >= 4,
|
||
|
|
[`Object.assign`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
|
||
|
|
now offers the same functionality natively (but without the "deep copy" option).
|
||
|
|
See [ECMAScript 2015 (ES6) in Node.js](https://nodejs.org/en/docs/es6).
|
||
|
|
* Some native implementations of `Object.assign` in both Node.js and many
|
||
|
|
browsers (since NPM modules are for the browser too) may not be fully
|
||
|
|
spec-compliant.
|
||
|
|
Check [`object.assign`](https://www.npmjs.com/package/object.assign) module for
|
||
|
|
a compliant candidate.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
This package is available on [npm][npm-url] as: `extend`
|
||
|
|
|
||
|
|
``` sh
|
||
|
|
npm install extend
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
|
||
|
|
|
||
|
|
*Extend one object with one or more others, returning the modified object.*
|
||
|
|
|
||
|
|
**Example:**
|
||
|
|
|
||
|
|
``` js
|
||
|
|
var extend = require('extend');
|
||
|
|
extend(targetObject, object1, object2);
|
||
|
|
```
|
||
|
|
|
||
|
|
Keep in mind that the target object will be modified, and will be returned from extend().
|
||
|
|
|
||
|
|
If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
|
||
|
|
Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
|
||
|
|
Warning: passing `false` as the first argument is not supported.
|
||
|
|
|
||
|
|
### Arguments
|
||
|
|
|
||
|
|
* `deep` *Boolean* (optional)
|
||
|
|
If set, the merge becomes recursive (i.e. deep copy).
|
||
|
|
* `target` *Object*
|
||
|
|
The object to extend.
|
||
|
|
* `object1` *Object*
|
||
|
|
The object that will be merged into the first.
|
||
|
|
* `objectN` *Object* (Optional)
|
||
|
|
More objects to merge into the first.
