I am trying to use Reach Router to create a link that is not exact. I want users to be able to visit www.website.reset/... and land on the same page as www.website.reset/ . I haven't found a method to make links non-exact while using Reach Router. Is this a feature that is just missing?
What you're wanting is called a "trailing wildcard". You can see it in the documentation here:
https://reach.tech/router/api/RouteComponent
Please note that trailing wildcards will receive a 1 point penalty in the calculation of routes. This is laid out here.
