API and Usage

Important note: Do not embed url to readme, instead embed generated svg

• It takes time to perform audits of website. So embedding it directly in readme would not render due to server timeout. Instead you must first visit and download the svg from the api (by simply visiting api url with desired parameters). And then embed that svg to your README files.
• Typically it takes 10-15 seconds to obtain the results from pagespeed api
• Some servers don't allow (eg. google.com) or delay (eg. cloudflare) pagespeed crawler, so it may result in unexpected results.
• The result may fluctuate slightly sometimes.

API url

The api is called from https://pagespeed-insights.herokuapp.com

Simple usage

In simple form it will return result for all categories for desktop version of your website. Replace your_website_url with your website's url

https://pagespeed-insights.herokuapp.com?url=your_website_url

For example

https://pagespeed-insights.herokuapp.com?url=https://ankurparihar.github.io

Theme

Default result is theme-agnostic i.e. looks good in both light and dark environment. But you can force one of two additional themes that are light and dark.
