Installing non PHP libraries via Composer?

Question

PHP

Tell me in the project I need jquery and bootstrap to be downloaded to certain folders. A question actually in how to register ways for the similar? That is, it is also not necessary that autoload be created for these files, because this is pointless.
Now the System folder simply contains composer.json, php dependencies are installed and that's it.

Answer 1

Composer is a package manager for PHP. It’s better to sort out front-end things through Twitter Bower

Answer 2

"type": "file"
instead
of "type": "package"
from here
