I agree, pnpm is excellent. The node_modules directory can easily take up hundreds of megabytes, and the storage space savings that pnpm provides are really convenient when you write a lot of small projects with similar sets of dependencies. I did a comprehensive benchmarking comparison on npm, pnpm, and yarn a while back, and pnpm was the clear winner for my needs [1]. Those benchmarks are admittedly outdated now because, as this submission points out, npm 6 introduced significant improvements over npm 5. Despite that, pnpm is still an underappreciated contender in the space.
