# RouterRoute

**Kind:** Interface

**Source:** [`src/types.ts`](https://github.com/honojs/hono/blob/main/src/types.ts#L57)

`RouterRoute` describes a route registered with a router. It stores the route's base path, path, HTTP method, and handler so the router can match requests and invoke the associated handler.

## Properties

| Property | Type |
|---|---|
| `basePath` | `string` |
| `path` | `string` |
| `method` | `string` |
| `handler` | `H` |

  Router --> Handler
```

## Usage

```ts
interface RouterRoute<H> {
  basePath: string;
  path: string;
  method: string;
  handler: H;
}

type RequestHandler = (request: Request) => Response;

const getUserRoute: RouterRoute<RequestHandler> = {
  basePath: "/api",
  path: "/users/:id",
  method: "GET",
  handler: (request) => {
    return new Response(`Requested: ${request.url}`);
  },
};
```

## AI Coding Instructions

- Keep `basePath` and `path` separate so the router can compose the final route path.
- Match `method` values to the format expected by the router, such as `"GET"` or `"POST"`.
- Type `handler` with the handler signature used by the router implementation.
- Preserve the generic `H` type when passing routes through registration or matching code.
