在Chrome中，如何在Javascript中获得审核小组分数

Question

With Chrome 60 in Dev Tools, there is an Audits Panel with some scores (powered by Lighthouse ). The scores at the top for Progressive Web App, Performance, Accessibility, and Best Practices are your aggregate scores for each of those categories.

Do you think, it is possible to access these scores with some Javascript code within Chrome?

Answer 1

You can run Lighthouse from the command line :

npm install -g lighthouse
lighthouse --output=json --output-path=./report.json https://airhorner.com/

This will produce a ./report.json that can be consumed by your script.

It's also possible to run Lighthouse from within your node script. It's not described in the docs, but you can check out how other tools (eg webpack-lighthouse-plugin ) are doing it.
