Look into adding type safe routes instead of stringly types params.

What is the feature you are proposing?

Routes could look like this:

const user = defineRoute(
  {
    userId: param.path.string,
  },
  (p) => `/users/${p.userId}`
);

const { routes } = createRouter({
  home: defineRoute("/"),
  post: defineRoute({ postId: param.path.string }, (p) => `/post/${p.postId}`),
  about: defineRoute("/about"),
  user,
  userSettings: user.extend("/settings"),
  userActivity: user.extend("/activity"),
});

This have two benefits, inferring data from the route means you can straight up pass it to a component directly. The other benefit is when you're creating a link and need to pass it params, you get

<a
  href={routes.user({userId: "2").href}link</a>

And programatically redirecting would also be supported with types

  routes.post({ postId: "abc" }).push();
