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"
