BravoJS began life as a reference implementation of an unratified proposed draft for CommonJS Modules/2.0. Note that the CommonJS working group itself is now defacto defunct, meaning that Modules/2.0 will never become a standard. Other implementations referencing this draft include NobleJS and PINF. The current draft specification this code is based on has been included in the references directory.
BravoJS is an extensible CommonJS module system for the web browser, similar in principle to CommonJS Transport/C (e.g. RequireJS and AMD), but maintaining complete backwards compatibility with CommonJS Modules/1.1.1 modules, including lazy initialization and correct support for dependency graphs with cycles.
The extensibility of this module system makes it possible to write plug-ins to add features like
We intend to release both Web Worker and NodeJS plugins for BravoJS in the summer of 2019; they will appear in future versions of this package.
As the CommonJS Modules/2.0 specification is no longer being developed we have taken some liberties with BravoJS and are now targeting NodeJS modules and NPM packages in our development efforts. So far, we have

It is anticipated that core BravoJS continues to work with all browsers, going back as far as Internet Explorer 6, however, we are not testing on obsolete platforms at this time.
