Welcome to Beam 👋

A beautifully simple CLI for running Lighthouse audits on a statically generated (SSG) website.

Beam automates the process of testing a statically generated website during development by finding and testing the pages within your build directory. Beam strives to be simple-to-use with sensible defaults whilst allowing a range of useful options to customise it's behaviour to suit your needs.

Features:

• Interactive terminal GUI for viewing and exploring the Lighthouse audit results for each page.
• Supports Brotli compression so you can see the actual transfer sizes.
• Automatically crawls through your build folder to find all the pages to test.
• Glob patterns can be specified to customise the crawling results.
• Testing in mobile, desktop, or both Lighthouse presets.
• Ability to set page Media features (such as prefers-color-scheme).
• Ability to specify different Lighthouse options for each page.
• Save detailed Lighthouse reports to a folder of your choice.
