How to build a module and its dependencies in NodeJs

I've been trying to understand by reading many tutorials and documentation but I wasn't able to grasp a simple concept.

My project is quite simple so far. I did a "npm install remote-project" and it gives me something like that

<my root dir>
    <node_modules>
        <remote-project>
            <node_modules>
                <remote-project-dependencies-and-more-node_modules>

Is there a way to build only the remote project and all its dependencies into 1 file easily? Or do I have to compile them manually using grunt?

The reason I ask is that I'm sure there is a simple way to do that using a gruntfile or an utility.

Thanks in advance.
