There are several ways to install an extension into StarUML.

StarUML Extension Repository

StarUMLJS is part of the StarUML offical extension repository. Open the extension manager (Tools -> Extension Manager) and install the JavaScript extension.

  • You may have to reload StarUML or just restart to the application.

Current Status

  • Currently supports one way generation of JS code from a UML model.
  • Uses the standard prototype JS definition of a "class"

Supported UML Concepts

  • The tool currently supports a subset of the StarUML model:

    • Classes
    • Methods of classes (all treated as public)
    • Attributes of classes
    • Class Documentation
    • Method Documentation
    • Method Specification
    • Method Precondition
    • Method Postcondition
    • Method Parameters
    • Dependencies
    • Direct Association
    • Generalization


  • Please contribute, this project is by no means complete and is currently not stable.
  • Open dev tasks are:
    • Reverse code engineering
    • Other "class" definition styles
