It is released under the free, open-source MIT License.

Overview

MooTools provides the user with a number of options beyond native JavaScript. These include:

  • An extensible and modular framework allowing developers to choose their own customized combination of components.
  • MooTools follows object-oriented practices and the DRY principle.
  • An advanced effects component, with optimized transitions such as easing equations used by many Flash developers.
  • Enhancements to the DOM, enabling developers to easily add, modify, select, and delete DOM elements. Storing and retrieving information with Element storage is also supported.

The framework includes built-in functions for manipulation of CSS, DOM elements, native JavaScript objects, Ajax requests, DOM effects, and more. MooTools also provides a detailed, coherent application programming interface (API), as well as a custom downloads module allowing developers to download only the modules and dependencies they need for a particular app.

History

Valerio Proietti first authored the framework and released it in September 2006{{cite book | first1 = Aaron | last1 = Newton | title = MooTools Essentials: The Official MooTools Reference for JavaScript and Ajax Development | publisher = Apress | edition = 1st | pages = xvi | date = September 18, 2008 | isbn = 978-1-4302-0983-6 | url = http://apress.com/book/view/1430209836 | first1 = Aaron | last1 = Newton | title = MooTools Essentials: The Official MooTools Reference for JavaScript and Ajax Development | publisher = Apress | edition = 1st | pages = xv | date = September 18, 2008 | isbn = 978-1-4302-0983-6 | url = http://apress.com/book/view/1430209836

Whereas Prototype extended—prototyped—many of JavaScript's native String, Array, and Function objects with additional methods, Proietti desired a framework that (at the time)Version 1.6.1 of Prototype includes "an element metadata storage system." Prototype 1.6.1 released by Sam Stephenson, written September 1st, 2009. Retrieved March 21, 2010. further extended the native Element object as well to offer greater control of the Document Object Model (DOM).Note that MooTools does not extend the native Object—all JavaScript primitives like String and Function inherit from it—but instead provides a convenient Hash for the purpose: Think of it like having a set of utility methods that allow for nearly effortless object manipulation of regular JavaScript objects that are otherwise unaffected by the process.

Components

MooTools includes a number of components, but not all need to be loaded for each application. Some of the component categories are:

  • Core: A collection of utility functions that all the other components require.
  • More: An official collection of add-ons that extend the Core and provide enhanced functionality.
  • Class: The base library for Class object instantiation.
  • Natives: A collection of JavaScript Native Object enhancements. The Natives add functionality, compatibility, and new methods that simplify coding.
  • Element: Contains a large number of enhancements and compatibility standardization to the HTML Element object.
  • Fx: An advanced effects-API to animate page elements.
  • Request: Includes XHR interface, Cookie, JSON, and HTML retrieval-specific tools for developers to exploit.
  • Window: Provides a cross-browser interface to client-specific information, such as the dimensions of the window.

Browser compatibility

MooTools is compatible and tested with:

Emphasis on modularity and reusability

Every JavaScript framework has its philosophy, and MooTools is interested in taking full advantage of the flexibility and power of JavaScript in a way that emphasizes greater modularity and code reuse. MooTools accomplishes these goals intuitively to a developer coming from a class-based inheritance language like Java with the MooTools Class object.

Class is an object of key/value pairs containing either properties or methods (functions). Class is effortlessly mixed and extended with other Class instantiations allowing for the most excellent focus of MooTools: Code reuse achieved through maximizing the power of JavaScript's prototypical inheritance but in a Class object syntax more familiar to classical inheritance models.

Object-oriented programming

MooTools contains a robust Class creation and inheritance system that resembles most classically based Object-oriented programming languages. For example, the following is MooTools' equivalent of the examples in Wikipedia's polymorphism page:

::code[lang=javascript] var Animal = new Class({

initialize: function(name) {
    this.name = name;
}

});

var Cat = new Class({ Extends: Animal,

talk: function() {
    return 'Meow!';
}

});

var Dog = new Class({

Extends: Animal,

talk: function() {
    return 'Arf! Arf!';
}

});

var animals = { a: new Cat('Missy'), b: new Cat('Mr. Bojangles'), c: new Dog('Lassie') };

Object.each(animals, function(animal) { alert(animal.name + ': ' + animal.talk()); });

// alerts the following: // // Missy: Meow! // Mr. Bojangles: Meow! // Lassie: Arf! Arf! ::
