I'm curious about the differences between pnpm and npm. Do they both use the same packages? If not, how do they differ in terms of package management and storage?

Both pnpm and npm use the same package registry, but they handle package storage in different ways. npm tends to store dependencies in a nested structure, which can lead to duplication across projects. On the other hand, pnpm installs packages once and links them, which saves space and avoids duplicates.

According to pnpm's documentation, the key feature is its use of a global cache for packages. This means that if you've installed a package for one project, you can easily use that cached version in another project without having to redownload it. This system is efficient, even allowing shared files from different package versions to save on storage.

The main difference is how they utilize disk space. npm downloads the same packages for every project, which can waste a lot of storage. In contrast, pnpm stores most packages centrally and creates symlinks to them in your project's node modules, so if you have multiple projects using the same packages, they only need to be downloaded once.
