• You can access and add additional property to the request object before the controllers process it.

• Open middleware file, middleware/support.ts:

    import type { Callback, Request } from "../deps.ts";
    export const options = {
      methods: ["GET", "POST"],
    };
    export default (request: Request, next: Callback) => {
      request.hello = "with middleware";
      next();
    };
