Where is the right place to store npm modules?

Question

npm

Hello. For a long time now, the following question has arisen for me - is it right to constantly download npm modules into each project? For example, I have 3 test projects and each of them has a module like laravel-elixir. In itself, it has a bunch of additional dependencies. For such options, I use the command npm link package, but I'm not sure if this is the right way. Wanted to know if keeping the same modules in every project is really the norm, or is there another solution? For example, install them globally.
