Can NPM suggest additional and optional packages after `npm install` command?

Question

Can NPM suggest to install additional and optional packages after npm install command? Something along the lines of how it is done in Composer ?

There is a optionalDependencies entry, but its description looks like a propose of this option is slightly different.

Answer 1

cd somedir npm install . or

npm install path/to/somedir somedir must contain the package.json inside it.

It knows about git too:

npm install git://github.com/visionmedia/express.git
