A general purpose browser-side CommonJS module loader
Yabble is a general purpose browser-side CommonJS module loader. Other similar module loaders are available, but Yabble strives to be a flexible loader in a small package.

Features:
- Compliant with Modules 1.1.1
- Supports async XHR/eval()
- Allows the use of non-transport-wrapped module code for quick development
- Supports script tags with a Transport format
- Easier debugging, potential for file concatenation
- Supports Transport/D and Transport/C
- Supports require.ensure() for lazy-loading modules
- Passes unit tests on YUI's A-grade browsers
- Includes a tool for automatically wrapping modules in a Transport format
- Small size (<600 lines, ~15kb raw, ~5kb minified, and ~2kb when minified/gzipped)
Roadmap:
- Stability
- Even more cross-browser testing
- More unit tests for Async/A
- Features
- Async/A error handling once its decided (maybe before)
- Tested support for loading from another domain (it may work now..)
- Documentation
- Tooling
- Currently under-developed. Not recommended to use.
- Use loader code in tooling (no copy/paste code)
- Explicit support for concatenated Transport files tooling (loader should already support)
- Expand supported engines for tooling (node.js)
- Better consideration for platform (line endings, encoding, etc)
Usage:
require.setModuleRoot(path)
Use this to configure the root path to find modules. Think of this as a single entry in require.paths.
require.useScriptTags()
The default behavior is to use XHR+eval() and expects unwrapped modules. Call this method to configure Yabble to use script tags and expect wrapped modules.
require.run(programId)
This kicks off an application using the specified module ID.
require.ensure(dependencies, callback)
See Async/A for more details. Can be used to retrieve modules and run code without using require.run().
See unit tests for example usage.
