NestJs - How to get url of handler?

I want to redirect user to another url in my server, but I do not want to hardcode url like res.redirect('/hello_world'). Instead I want to just specify handler's url of specified controller like res.redirect(HelloWorldController.handlerName.url) where HelloWorldContoller is 

@Controller()
export class HelloWorldController {
    @Get('hello_world')
    handlerName(): string {
        return 'Hello World!';
    }
}

For example, you can use Reflect to get metadata like this:

import { PATH_METADATA } from '@nestjs/common/constants';

@Controller('api')
export class ApiController {
  @Get('hello')
  root() {
    let routePath = Reflect.getMetadata(PATH_METADATA, StaticController);
    routePath += '/' + Reflect.getMetadata(PATH_METADATA, StaticController.prototype.serveStatic);
    console.log(routePath); will return `api/hello`
    return {
      message: 'Hello World!',
    };
  }
}
  1. We get api metadata
  2. Then it's methods

Why it returns api/hello if I need a path not of self url, but other controller's url?

Here StaticController is used as an example, You can import any other controllers and pass it to Reflect.getMetadata(PATH_METADATA, AnyOtherController);
