How to quickly download a large number of packages from npm?

Question

npm

If you download some heavy packages via npm, they will download quite quickly (of course, it depends on the speed of the Internet connection). The packages themselves consist of a large number of small files, and if the same files that make up npm packages are downloaded via direct links through some kind of download manager, then I'm sure the download time will be much longer.
Even if you select a large number of small files in Google Drive, the service will first archive them for a long time, and only then will it let you download the archive.
What is the secret to quickly downloading a lot of small files in npm?
