TaffyDB (taffy.js)

TaffyDB is an open source library that brings database features into your JavaScript applications.

Introduction

How you ever noticed how JavaScript object literals look a lot like records? And that if you wrap a group of them up in an array you have something that atcs a lot like a database table? TaffyDB brings powerful database funtionality to that concept and rapidly improves the way you work with data inside of JavaScript.

What makes it sticky

• Extremely fast
• Powerful JavaScript centric data selection engine
• Database inspired features such as insert, update, unique, count, etc
• Robust cross browser support
• Easily extended with your own functions
• Compatible with any DOM library (jQuery, YUI, Dojo, etc)
• Compatible with CommonJS (node.js, etc)

Create a DB

Just pass in JSON:

var products = TAFFY([{
	"item":1,
	"name":"Blue Ray Player",
	"price":99.99
}, {
    "item":2,
    name:"3D TV",
    price:1799.99
}]);

Find data

Use JSON to compare:

var item1 = products({item:1});
// where item is equal to 1
var lowPricedItems = products({price:{lt:100}});
// where price is less than 100
var blueRayPlayers = products({name:{like:"Blue Ray"}});
// where name is like "Blue Ray"

Use data

// update the price of the Blue Ray Player to 89.99
products({item:1}).update({price:89.99});
// loop over the records and call a function
products().each(function (r) {alert(r.name)});
// get first record
products().first();
// get last record
products().last();
// sort the records by price descending
products.sort("price desc");
// select only the item names into an array
products().select("name"); // returns ["3D TV","Blue Ray Player"]
// inject values from a record into a string template
var row = products({item:2}).supplant("<tr><td>{name}</td><td>{price}</td></tr>");
// row now equal to "<tr><td>3D TV</td><td>17999.99</td></tr>"
