Creating a decorator and use it within the application from external provider

[tonydspaniard]

Looks like this #499 issue, but I also tried creating a dynamic root module:

import { Module } from '@nestjs/common';
import { AWS_MODULE_CONFIG_TOKEN, AWS_S3_CLIENT_TOKEN } from './constants';
import * as ClientS3 from '@aws-sdk/client-s3';
import { S3 } from '@aws-sdk/client-s3';
import { createConfigurableDynamicRootModule } from '@golevelup/nestjs-modules';
import { AwsModuleConfig } from './aws-vendor.interfaces';
import { AwsS3Service } from './aws-vendor-s3.service';

@Module({})
export class AwsVendorProviderModule extends createConfigurableDynamicRootModule<AwsVendorProviderModule, AwsModuleConfig>(
  AWS_MODULE_CONFIG_TOKEN,
  {
    providers: [
      {
        provide: AWS_S3_CLIENT_TOKEN,
        useFactory: ({ s3 }: AwsModuleConfig): S3 => {
          return new S3(<ClientS3.S3ClientConfig>s3);
        },
        inject: [AWS_MODULE_CONFIG_TOKEN]
      },
      AwsS3Service
    ],
    exports: [AWS_MODULE_CONFIG_TOKEN, AWS_S3_CLIENT_TOKEN, AwsS3Service]
  }
) {
}

Added to the App.Module, but when I try to use the AwsS3Service that contains the decorator, it fails even if I add AwsVendorProviderModule.externallyConfigured(AwsVendorProviderModule, 0), to the module that contains the issue. It gotta be something very simple, but I cannot figured it out...

I solved doing the following, that looks to me like a hack:

• created AwsProviderModule Global
• forwardRef for AwsS3Service on services using it @Inject(forwardRef(() => AwsS3Service))
• and this was the weirdest, I had to use the same technique for the services using AwsS3Service on the controller's constructor even though they were imported as providers.

Currently works, but I feel this is a hack. If you have a better solution I am all ears. Thank you!

Found the problem, the issue was to make use of path aliases within the structure of the application, changing them to relative paths everything works.
