Node set-up in an enterprises

I have just had a quick introduction on Node. I have not worked on it but It looks like my knowledge on Maven helps a bit to make it easy.

Would it be wrong if I say 1. Node is like a maven central repository where all the dependencies can be found? 2. package.json is like pom which lists all the dependencies. 3. In a big enterprises, there would be a local nexus repository for Maven dependencies. How would that be for node package.json ? would there be local nexus repositories for node devDependencies as well ?

Apart from this, node provides a run time environment for running java script. I know its not exactly same, but just using the analogy to make it easy for me to understand.

Thanks in advance.
