        return { "Content-Type": type };
    })
    @Get()
    hello2() {
        return Deno.readFile('./path/to/file');
    }
}
...

Middlewares

@Wares(…middlewares).

...
@Controller("/hello")

    @Wares((rev, next) => {
        rev.foo = "foo";
        next();
    })
    @Get()
    hello({ foo }: RequestEvent) {
        return foo;
    }
}
...

Inject

@Inject(value: any, …args: any).

...

class HelloService {

    async findAll() {
        const data = await db.findAll();
        return { data, status: 200 }; 
    }

    async save(body) {
        await db.save(body);
        return { message: 'success save', status: 201 }; 
    }
}

@Controller("/hello")
class HelloController {

    @Inject(HelloService)
    private readonly service!: HelloService;

    @Get()
    findAll() {
        return this.service.findAll();
    }

    @Status(201)
    @Post()
    save({ body }: RequestEvent) {
        return this.service.save(body);
    }
}
...

addControllers

addControllers(classControllers: class[]).

...
app.use(addControllers([HelloController, OtherController]));
