Any way to automatically copy packages if they are already installed rather than download them

Is there a way for node to be aware of dependancies already downloaded? Like can I set up a folder where all the packages I download keep getting saved to and whenever I run npm install package it first checks if I have that package in my folder and if it is it copies the package from there instead of downloading it?Asking because I have slow internet speed and having to set up multiple react projects takes more time than what I actually spend coding. :D
