records? And that if you wrap a group of them up in an array you have
something that looks a lot like a database table? We did too.
We created TaffyDB easily and efficiently manipulate these 'tables'
with a uniform and familiar SQL-like interface.
We use TaffyDB instead of ad-hoc data manipulation routines throughout our applications. This reduces development time, improves performance, simplifies maintenance, and increases quality.
Please see the official website for more complete documentation.
What makes it sticky
- Extremely fast
- SQL inspired features such as insert, update, unique, count, and more
- Robust cross browser support
- Easily extended with your own functions
- Compatible with any DOM library (jQuery, YUI, Dojo, etc)
TaffyDB is compatible with all modern browsers: IE9+, FF3+, Safari 5+, and Chrome 1.0+. It also works in NodeJS 0.10+.
Create a DB
Just pass in a JSON array:
var product_db =;
// where item is equal to 1var item1 = ;// where price is less than 100var lowPricedItems = ;// where name is like "Blue Ray"var blueRayPlayers = ;// get first record;// get last record;
Example record manipulation
// update the price of the Blue Ray Player to 89.99;// loop over the records and call a function;// sort the records by price descendingproducts;// select only the item names into an array; // returns ["3D TV","Blue Ray Player"]// Inject values from a record into a string template.// Row value will be set to "<tr><td>3D TV</td><td>17999.99</td></tr>"var row =;
Use it in Node.JS
Node is easy to use in Node.JS. Simply install using
$ npm install --production taffy# and then in your codeTAFFY = taffy;
The automated regression test file
nodeunit_suite.js is an excellent
Help improve taffydb
TaffyDB has been used and refined for years for numerous production tools and commercial products. It is therefore is quite stable and reliable. However, we want expand our regression test coverage so we can easily improve the code with the confidence that we are unlikely to break exising capabilities.
Getting started with development
install_dev.sh script to install development utilities such as
uglifyjs to the
Running regression tests
Running the nodeunit regression test suite is simple:
cd taffydb/install_devsh # as abovebin/nodeunit /nodeunit_suitejs
Please do not send a pull request unless your changes have passed these tests. We check, you know :)
Adding to regression tests
We wish to substantially expand the number of tests, and your
help is welcome! The code,
nodeunit_suite.js, should be easy to adjust.
Pull requests that include regression test inclusions are very much
appreciated. Alternately, if you just send along a test scenario, we'd be
happy to include it in the suite, time permitting.
