vpo's Introduction

VPO

Build Status

Value/path helper functions for javascript objects

It's a set of simple functions that let you query or set values on your objects by a given string path.

How to get it:

Either:

git clone git://github.com/unlucio/vpo.git

or

npm install vpo

or

bower install vpo

Examples:

Given the following dummy object:

{
	key1: {
		foo1: {
			bar1: 'bao',
			bar2: 'bao'
		},
		foo2: {
			bar2: 'bao'
		},
		foo3: {
			bar3: 'bao'
		}
	},
	key2: {
		foo1: {
			bar1: 'bao',
			bar2: 'bao'
		},
		foo2: {
			bar2: 'bao'
		},
		foo3: {
			bar3: 'bao'
		}
	}
}

setting a value:

vpo.set(testObj, 'key1.foo2.bar2', 'resetBao');

getting a value:

vpo.get(testObj, 'key1.foo2.bar2');

getting a value specifing a default return value:

vpo.get(testObj, 'key1.foo2.barNoExists', 'default');

getting a value from a list of possible paths:

vpo.getSome(testObj, ['key5.foo2.bar2', 'key1.foo2.bar2']);

getting a value from a list of possible paths specifing a default return value:

vpo.getSome(testObj, ['key1.foo2.barNoExists', 'key1.foo12.barNoExists', 'key14.foo2.barNoExists'], 'default');

getting parts of your objects based on paths:

vpo.pick(testObj, ['key1.foo1.bar2', 'key1.foo4.bar2', 'key2.foo1']);

/**
will yield ==>
{
	key1: {
		foo1: {
			bar2: 'bao'
		}
	},
	key2: {
		foo1: {
			bar1: 'bao',
			bar2: 'bao'
		}
	}
}
*/

I'm not sure who will ever be so "brave" to use it, but I'll leave it in since a dear friend of mine LOVES it :D

For convenince you can attach VPO to Object's prototype and have all your objects with 2 new methods:

vpo.setOnObjectPrototype();
