Benchmarks of JavaScript Package Managers

Last benchmarked at: Sep 20, 2021, 2:47 AM (daily updated).

This benchmark compares the performance of npm, pnpm, and Yarn (both regular and PnP variant).

Here's a quick explanation of how these tests could apply to the real world:

  • clean install: How long it takes to run a totally fresh install: no lockfile present, no packages in the cache, no node_modules folder.
  • with cache, with lockfile, with node_modules: After the first install is done, the install command is run again.
  • with cache, with lockfile: When a repo is fetched by a developer and installation is first run.
  • with cache: Same as the one above, but the package manager doesn't have a lockfile to work from.
  • with lockfile: When an installation runs on a CI server.
  • with cache, with node_modules: The lockfile is deleted and the install command is run again.
  • with node_modules, with lockfile: The package cache is deleted and the install command is run again.
  • with node_modules: The package cache and the lockfile is deleted and the install command is run again.
  • update: Updating your dependencies by changing the version in the package.json and running the install command again.
