Benchmarks of JavaScript Package Managers
Last benchmarked at: Oct 22, 2023, 2:46 AM (daily updated).
This benchmark compares the performance of npm, pnpm, Yarn Classic, and Yarn PnP (check Yarn's benchmarks for any other Yarn modes that are not included here).
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, nonode_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 thepackage.json
and running the install command again.
