matchRoutes

declare function matchRoutes(
  routes: RouteObject[],
  location: Partial<Location> | string,
  basename?: string
): RouteMatch[] | null;

interface RouteMatch<ParamKey extends string = string> {
  params: Params<ParamKey>;
  pathname: string;
  route: RouteObject;
}

matchRoutes runs the route matching algorithm for a set of routes against a given location to see which routes (if any) match. If it finds a match, an array of RouteMatch objects is returned, one for each route that matched.

This is the heart of React Router's matching algorithm. It is used internally by useRoutes and the <Routes> component to determine which routes match the current location. It can also be useful in some situations where you want to manually match a set of routes.
