Why isn't Google's Closure library hosted on their CDN?

Google hosts a number of JavaScript libraries such as jQuery and dojo on their CDN. For some reason, their own Google Closure library does no开发者_JAVA技巧t seem to be included. Is there a hosted version of the Closure library?

It's not included because Closure is intended to be used with the compiler; a hosted version would need to include the entire library and defeat the purpose of building minified libraries containing only the features you need.

You can link to their repository:

<script src='https://cdn.rawgit.com/google/closure-library/master/closure/goog/base.js'></script>

good enough for demos or local development. As other answer suggested, production should use compiled code, it is well worth it.
