# Benchmarks of JavaScript Package Managers

This benchmark compares the performance of [npm](https://github.com/npm/cli), [pnpm](https://github.com/pnpm/pnpm) and [Yarn](https://github.com/yarnpkg/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.
