Sphinx

Recursively merges and guards your objects against unwanted tampering.

Features

Sphinx guards your objects during a merge by allowing you to:

• only change the values for properties that exist on the destination object.
• only change the values for properties that are of the same type as the destination object.

Getting Started

npm install --save sphinx

Usage

var sphinx = require( "sphinx" );
 
var destination = { foo: "bar" };
var source      = { foo: "qux" };
 
var merged = sphinx.merge( destination, source );
//=> { foo: "qux" }

Examples

• Trying to add a property that doesn't exist on the destination object.

var destination = { foo: "bar" };
var source      = { baz: "qux" };
 
var merged = sphinx.merge( destination, source );
//=> [Error: Property "baz" does not exist on destination object]

• Trying to merge a property of a mismatched type.

var destination = { foo: "bar" };
var source      = { foo: 1 };
 
var merged = sphinx.merge( destination, source );
//=> [TypeError: Expected property "foo" to be a [object String]]

API

sphinx.merge( destination, object )
