pnpm is a fast, disk-efficient JavaScript package manager that uses a content-addressable store and hard links. Strict node_modules structure prevents phantom dependencies.
Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“3x faster installs, strict dependency resolution, and disk space savings. The best JavaScript package manager.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Strictly better than npm in every measurable way. The strict node_modules prevents dependency bugs.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“pnpm's content-addressable store is the right architecture. Bun's speed will push it further.”
