There is a third alternative with a clear advantage over these two. PNPM is an NPM client that installs versioned packages into a central location and uses file system links within the 'node_modules' folder of individual projects. For a typical developer with many local projects this is a huge disk space saver. It also uses the original and much clearer nested structure of node_modules. I don't know why NPM didn't adopt the shared package approach, or why yarn didn't either, but PNPM gets it right.

I did list that one in my comment :)
