generatePath

declare function generatePath<Path extends string>(
  path: Path,
  params?: {
    [key in PathParams<Path>]: string;
  }
): string;

generatePath interpolates a set of params into a route path string with :id and * placeholders. This can be useful when you want to eliminate placeholders from a route path so it matches statically instead of using a dynamic parameter.

generatePath("/users/:id", { id: "42" }); // "/users/42"
generatePath("/files/:type/*", {
  type: "img",
  "*": "cat.jpg",
}); // "/files/img/cat.jpg"
