Lighthouse Batch Reporter

Supports executing Lighthouse analysis over a number of sites in sequence and generating a summary report including all of their scores. Scores are calculated from the average score between Performance, PWA, Accessibility and Best Practice and SEO sections.

Also writes out the full json report for each site and optionally an html report too.

CLI

Install globally

npm install lighthouse-batch -g

Example usage

lighthouse-batch -s https://www.bbc.com,https://housing.com

This will generate the following files under the /report/lighthouse folder.

www_bbc_com.report.json   // Full results for bbc.com
housing_com.report.json   // Full results from housing.com
summary.json              // Summary of results with scores out of 100

Example summary.json

    "name": "www_bbc_com",
    "file": "www_bbc_com.report.json",
