npm instead of bower. How to separate libraries and packages for assembly (eg CSS compilation)?

Question

Node.js

We are going to switch to nmp instead of bower (as a dependency manager).
In bower, all installed libraries were stored in bower_component or some other separate folder.
Npm dumps everything into node_modules by default, mixing code libraries, gulp, preprocessor compilers, and the like.
Is there any way to separate them?

Answer 1

Why separate them? The assembler will decide which files to include and which not. The “include all files from the vendor folder” strategy is a road to nowhere.
