Not working on NextJS app router

[thienthanit04]

I'm using NextJS 13.3.4 for app router and trying to apply this package to my project.
But I got this bellow exception.

• error Detected default export in '..../api/auth/verify-email/resent/route.ts'. Export a named export for each HTTP method instead.
• error No HTTP methods exported in '..../api/auth/verify-email/resent/route.ts'. Export a named export for each HTTP method.

Exact same error for me
It's seems that the new way Next js structure the API in route and a set of named function (get, post, ... ) doesn't fit the way Next-API-Decorator createHandler works

Testing some workaround but lot of classes use NextApiRequest and NextApiResponse instead of the new NextRequest or NextResponse.
Also createHandler should return a set of decorated function or allow more simple process like

import {Body,Post} from 'next-api-decorators'
import { ValidateIdentityDto } from "../../dto/validate-identity.dto";

class IdentityController {

  @Post()
  async validateIdentity(@Body() body: ValidateIdentityDto) {
    console.log(body)
    return Response.json({val:"identity verified",body})
  }
}
// Create the controller 
const controller = new IdentityController();

export async function POST(req: Request, res: Response): Promise<Response> {
  const body = await req.json()
  //Use controller function
  return controller.validateIdentity(body) 
}

The provided code above not working, the @Post decorator throw an error.

Nothing is really usable in app router.
I'm a huge fan of NestJS decorator, allow it in NextJS is game changer, but it needs app router support.
@ggurkal or @leeuwis any roadmap to support app router ?
I've forked the repo, but some part of the code is outside of my skills, maybe team can helps for app router implementation :)

Hello !
I just posted a research around decorator around the new Route handler in NextJS App router to find a possible solution outside this repo and potentially fork and update with the final solution

I also create a gist to make my own research around decorator https://gist.github.com/SuperstrongBE/2d4e6d1aac89797270745f22c9ba047b
Feel free to reach me if you have advices / tips

I was also working on this, as having a robust easy routing through classes and decorators is a must for me. So even here my attempt with reference to @SuperstrongBE inspirations. Still working on it, but got path routing down, with args being passed down.
