#### Deep extend with customizable behavior for Node.js.

"Extedify" is a lightweight wrapper over lodash's _.merge (like a deep _.extend) with customizable handling of arrays, booleans, numbers and strings.

(By default, extedify will behave exactly like lodash's _.merge.)

Installation

``javascript
npm install extendify
`

Usage


`javascript
var extendify = require('extendify');
myExtend = extendify({
// options
});
`

Options

- inPlace – Override the 'source' with the result?
- true (default)
- false
- isDeep – Use deep extend?
- true (default)
- false
- arrays – How to handle arrays?
- replace (recommended)
- concat
- merge (default)
- or
- and
- booleans – How to handle booleans?

Example

Let's get an _.extend function that
- returns a copy/clone,
- replaces arrays,
- supports nested objects (also known as deep extends).

`javascript
_.extend = extendify({
inPlace: false,
isDeep: true,
arrays : 'replace'
});

object1 = {
a:{
list: [1, 2]
},
b: 4
};

object2 = {
a:{
list: [3]
}
};

var result = myExtend(object1, object2);
/*
{
a: {
list: [3]
},
b: 4
}
*/
``
