smartprop

Smart and effortless json data search in JavaScript

Description

Smartprop is used for searching a value assigned to a key in a complicated nested object.

Examples

SmartProp

var SmarProp = require("smartprop").SmartProp
var SmartObject = require("smartprop").SmartObject
data = {
  item : {
    owner : {
      id : 1,
      profile : {
        name: "Chris"
        reputation : 10
        his_site_url : "www.site.com"
      }
    }
    price: 10 
  }
}
var name = new SmartProp("name")
name.findIn(data)   //=> "Chris"

var price = new SmartProp("price")
price.findIn(data)  //=> 10

var site = new SmartProp(/site/)
site.findIn(data)   //=> "www.site.com"

SmartObject

var smartobject = new SmartObject({name : "name", price: "price", website: /site/})
smartobject.map(data)    //=> {name : "Chris, price: 10, website: www.site.com"}

Performance

If You wonder if:

(new SmartProp("name")).findIn(data)

than

data["item"]["owner"]["profile"]["name"]

SmartProp and SmartObject automatically cache the location of the property, and once fed the similar data it uses the same code You'd use while not using the smartprop at all. So it is less performant, but just the first time it is used.
