Thanks for the correction, after looking at the types I'm guessing it's this bit: https://github.com/molefrog/wouter/blob/v3/packages/wouter/t...
Yep! That's the type. It used to be a lot more complicated if I remember correctly, but looks like the author is importing a type from that "regexparam" package to do it now.
It does, assuming you're talking about automatically parsing "/foo/:id" and getting a typed "{ id: string? }" route params object out of it? Wouter does that when using typescript.
