Today most developers already know how to quickly code a menu or a layout structure, but there’re always a great difficulty when coding a form, either contact, login, newsletter, comment etc.

Formee is nothing but a framework to help you develop and customize web based forms. works with the technique provided by Fluid 960 Grid System to compose the form’s layout, allowing total flexibility to put it in any website or web system.

The form has a structure built around percentage widths, thus allowing its inclusion in any project, adapting to the space available. Formee has its structural code independent of the style codes, facilitating the complete customization and manteinance of the form.

The form was built with care to preserve web standards and their semantic values, working with the smallest possible amount of tags and according to the W3C rules.

Tangle is a JavaScript library for creating reactive documents. Your readers can interactively explore possibilities, play with parameters, and see the document update immediately. It is a lightweight library that provides a simple API for tangling up the values in your document. Tangle.js has no dependencies, and works with any JavaScript framework, or none at all.

TangleKit is an optional collection of UI components that let your readers adjust values and visualize the results. You can grab whichever components you want, use them, extend them, modify them, or just learn from them and make your own. TangleKit also includes (and depends on) a few helpful libraries, such as MooTools, sprintf, and BVTouchable.

jwerty is a JS lib which allows you to bind, fire and assert key combination strings against elements and events. It normalises the poor std api into something easy to use and clear. All jwerty events will require a jwertyCode in some way. jwertyCodes can be passed as strings, or arrays, strings being the easiest way to express a combo.

jwerty is a small library, weighing in at around 1.5kb bytes minified and gzipped (~3kb minified). jwerty has no dependencies, but is compatible with jQuery, Zepto or Ender if you include those packages alongside it.

Addy has written a really nice article to discuss an effective set of Patterns For Large-Scale JavaScript Application Architecture. Large-scale JavaScript apps are non-trivial applications requiring significant developer effort to maintain, where most heavy lifting of data manipulation and display falls to the browser.

If working on a significantly large JavaScript application, remember to dedicate sufficient time to planning the underlying architecture that makes the most sense. It’s often more complex than you may initially imagine. Take a look at this great article, I am sure you will learnt a lot too.

Spin.js uses the CSS3 to render the UI, falling back to VML Internet Explorer. If supported by the browser, @keyframe rules are used to animate the spinner. The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.

There is no images and external CSS for Spin.js. It is highly configurable, and works in all major browsers, including IE6. It is smaller than an animated GIF (2.8K minified, 1.7K gzipped).

Would you like to create a game similar to Angry Birds in Javascript? box2dweb can probably help you with that. box2dweb is a port of Box2DFlash 2.1a to JavaScript. The Box2D physics engine was developed by Erin Catto.

There already exists a port to JavaScript called Box2dJs, but it’s not up-to-date and you have to import a big amount of JavaScript files in every project, whereas this version is stored in a single file.

melonJS is the result of our enthusiasm and past experiments with Javascript, and came from the feeling that no simple, free and standalone library was available to develop games. And although still a big work in progress and not yet bug free, melonJS already allows to easily create some nice games.

melonJS integrates the popular Tiled map format, allowing to easily design levels using the Tiled map editor, and to focus on the game features itself. melonJS is compatible with the various existing browsers. However, as of today, Google Chrome 12 (or upper) is highly recommended.

Sinon.JS is a Standalone test spies, stubs and mocks for JavaScript. No dependencies, works with any unit testing framework. A test spy is a function that records arguments, return value, the value of this and exception thrown (if any) for all its calls.

Test spies are useful to test both callbacks and how certain functions/methods are used throughout the system under test. Use a stub when you want to control a method’s behavior from a test to force the code down a specific path. Mocks are fake methods (like spies) with pre-programmed behavior (like stubs) as well as pre-programmed expectations.
