Cet outil scanne les sites qui lui sont paramétrés dans _data/sites/*.js. Il vérifie des score de performances, SEO, best practices et accessibilité grâce à Lighthouse.

speedlify

After you make a fast web site, keep it fast by measuring it over time. Read Use Speedlify to Continuously Measure Site Performance. Created by @zachleat.

• Requires Node 12+
• Each file in _data/sites/*.js is a category and contains a list of sites for comparison.

Run locally

After cloning you’ll probably want to delete the initial _data/sites/*.js files and create your own file with a list of your own site URLs!

npm install
npm run test-pages
npm run start

Known Limitations

• If you change a URL to remove a redirect (to remove or add a www., moved domains, etc), you probably want to delete the old URL’s data otherwise you’ll have two entries in the results list.
• When running on Netlify, a single category has a max limit on the number of sites it can test, upper bound on how many tests it can complete in the 15 minute Netlify build limit.
• The same URL cannot be listed in two different categories (yet).

Pay for something better

Speedlify is intended as a stepping stone to more robust performance monitoring solutions like:

• SpeedCurve
• Calibre
• DebugBear
