🔥 Live from TPAC:
Native routing coming to the web platform!
First step was URLPattern.
Next is matching routes in CSS¹

Exciting stuff.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.
