yarn-npm-performance

This package can be used to get performance information for your repo when comparing yarn and npm install.

The test cases are below:

• yarn, no lockfile, no node_modules
• yarn, has lockfile, no node_modules
• yarn, has lockfile, has node_modules
• npm install, no node_modules
• npm install, has node_modules

This will run each test case 7 times, with the output is provided via CLI and as a simple CSV. Test are run sequentially to ensure a more accurate performance time. It may take a while due to this, so please be patient.

Installation

This is a tool that is intended to be run on your repo and not in it and therefore should be installed globally via npm install @andrew-codes/yarn-npm-performance -g.

Running

Change into your repo's directory and run yarn-npm-performance. This will run one test run for each test case. Optionally provide a number of test runs to process via yarn-npm-performance 7. Once finished, you will find the output in the file yarn-versus-npm-install-performance.csv.
