Yajsml is a server-side component that allows JavaScript code to be distributed in a reliable and performant way. Its three features are:

- Proxy pass through for individual resource requests. - Bulk responses for requests of closely associated resources (e.g. dependencies) when a request specifies a JSONP-style callback. - Canonical packaged resources where requests for disparate resources may be fulfilled through a redirect to one canonical packaged resource (which exploits warmed caches).

The tool’s interface is simple enough that there is no need for a prescribed implementation on the client-side. That said, the require-kernel is a terse implementation of a CommonJS module manager that can use all the features in yajsml.
