Joose is a self-hosting meta object system for JavaScript with support for classes, inheritance, mixins, traits, method modifiers and more.

Joose makes object-oriented programming with JavaScript easy, declarative and very productive. The Joose meta-object system is multi-paradigm. It supports class-based and prototype-based programming styles as well as class-based inheritance and role-based extention.

Examples

Class Browser

Joose provides very easy to use introspection facilities for Joose classes, modules and prototypes. The class browser example uses these facilities to show you information about the classes which are currently loaded. Its layout is based on the good old class browser included with VisualWorks Smalltalk.

Object-Relational Mapper

This example demonstrates a simple object relational mapper for the client-side SQLite database provided by Google Gears.

Credits

Joose was heavily inspired by Moose, the post-modern object system for Perl 5.
