/js directory mime is application/javascript. Is it correct?

[kadishmal]

Trying to get a mime type of a directory in /js request.uri, the module returns application/javascript. Is this the expected behavior? If it is, please explain why.

In my application, when a request comes for a static file, I check whether user has access to this type of static resource. For this reason I need to determine the file mime. Sometime when users enter /js, /css, in which case mime module returns as if request comes for JS or CSS files, respectively. Obviously, this is a wrong behavior.

The expected behavior in such cases is to receive null or '' (an empty string) which would be easy to handle in the application.

node-mime is only looking at the name string you give it; it does not use any filesystem information to determine mime type. I agree this case is debatable, but I don't think it's unreasonable to expect people who care about directory .vs. file type to do the necessary checks before calling into node-mime.
