Chiron

Chiron is a system of interoperable JavaScript modules. Chiron modules
conform to the “securable, interoperable JavaScript module
specification” 1. Chiron also provides a compliant module loader for web
browsers. This project strives to provide a coherent set of general
purpose modules for both client and server, and secure and non-secured
environments.

These modules presently include:

  • a type system
  • base types
  • general-purpose functions
  • events
  • encoding, decoding
  • hashing
  • caching

Usage

Chiron modules can be used both on the client and server side. Chiron
ships with a browser-based XHR module loader. ``modules.js`` is a script,
suitable for inclusion on with a ``<script>`` tag in a web page. The
script will instantiate a module system in the page. In the script tag,
put the identifier of your main module in the query string:


    <script src="path/to/modules.js?main"></script>

If your module library is in an alternate location, you can supply a
library path on the query string as well::


    <script src="/modules.js?path=/js/&main"></script>

Tools for bundling and minimizing modules for production are presently
being recreated for this version of Chiron.

modules.js leaves no trace of itself in the DOM or in the global scope
(it does not add any properties to the window object, and removes its
own <script> tag from the DOM. Thus, Chiron is very kind to its
neighbors, and most modules are designed deffensively and non-aggressively.

Installation

Chiron does not presently support installation, but there are plans to
eventually integrate with Narwhal 3 and whatever package management
system the Server-side JavaScript 4 “working group” ratifies.

Legal

Chiron is a component of the Tale web-game project.
