I like reading about new things that web browsers support, but I try to only care when they work in all three main browser engines and not just one or two.
This Deno program will read the contents of https://github.com/web-platform-dx/web-features that you’ve previously git cloned to your computer and spit out a long YAML list of features that are Baseline High (been working in all three engines for a while).
If you care about people using slightly older browsers, modify output so it gets the stringified YAML version of highs, not lows, and run it again.
Assuming you have Deno installed, either run deno task clone or inspect deno.json to see what Git repository you want to clone (maybe you prefer HTTPS clones).
Then run deno task once. You can, of course, run it more than once.
It sure would be cool if someone made an Atom feed of this kind of information.
