I maintain Nodemailer and moved to the zero dependency model years ago (Nodemailer only has some development dependencies needed to run the test suite but no production dependencies). Mostly though, because npm versions of that time were super slow – aggregating all modules into a single package took install time to around a single second while the same code separated into modules took like 15 seconds or more to install. It turned out to have other benefits as well. For example, it is far easier to support older platforms (Nodemailer supports all Node.js versions since Node v6) if your dependencies do not start using the latest ES syntax overnight.

nuance required:

- vet pnpm and the multiple dependency install

- consider bundling with roll-up for a dependency free userland experience and compare
