Router

Rover middleware needs a router to operate. Router is essentially an array of Route object.

The route interface

The route object is simple, it looks like this:

type Route = {
  path: string;
  handler(request: Request): Promise<Response>;
  method?: string;
};

Here,

• path is the url path which starts with a / for instance /blog
• handler is the handler function which accepts request as a param which is useful for inspecting requests
• method as the name suggests the http method like POST or GET. By default the method will be GET, if it's not explicitly defined.

Create Router

Creating router is simple, just call the built-in Router function and pass in an array of Route

For instance here's a demo router

router.js

const router = Router([
  {
    path: "/",
    handler: home_handler,
    method: "GET",
  },
  {
    path: "/blogs",
    handler: blog_handler,
    method: "GET",
  },
  {
    path: "/auth/login",
    handler: login_handler,
    method: "POST",
  },
]);

That's it, it's as simple as that. No need to make it any complex further. This design helps you keep a separate route tree for your application.
