Inspiration

After Google I/O 25, I have started learning about Baseline. With a time I wanted to see which new features are used by our product and other websites. But it wasn't possible. So I reached out to the webperformance community in Slack and Barry Pollard shared some insights on how to use Chrome internals to get the result. For this hackathon I decided to develop the idea and share with everyone as an open-source library.

What it does

The library lists all modern features used by a URL, along with their Baseline status. It loads a page with Headless Chrome, requests an internal UseCounter API, and maps WebDX ids to Baseline features. It uses internal Chrome's UseCounter API and maps detected features using API and web-features library.

What's next for baseline-url

If the library is popular, I will make a web tool for a quick access and sharing.
