pagespeed-score-local

Local Google PageSpeed Insights (PSI) score and metrics CLI

Get a score by running Lighthouse locally instead of the PSI API.

This a local version of the pagespeed-score module.

Why?

The goal is to get a PSI score:

• in CI and without public URL (e.g. staging environment on a private network)
• faster if possible (the Google API takes long to respond)

How

• using the same version of LightHouse as PSI
• using LightRider mobile config from the lighthouse module
• faster run by only getting metrics needed for the performance score
• doing multiple runs and outputting statistics

Ideas/TODO

• auto-calibrating CPU throttling using benchmark index
• maybe support more Lighthouse cli-flags
