NestJS - avoid setContext() in constructor on logger injection

Issue

In NestJS I have custom logger:

import { Injectable, Logger, Scope } from '@nestjs/common';

@Injectable({ scope: Scope.TRANSIENT })
export class LoggerService extends Logger {
  log(message: any) {
    super.log(message);
  }

  error(message: any) {
    super.log(message);
  }

  warn(message: any) {
    super.log(message);
  }

  debug(message: any) {
    super.log(message);
  }

  verbose(message: any) {
    super.log(message);
  }

  setContext(context: string) {
    super.context = context;
  }
}

It is registered globally:

import { Global, Module } from '@nestjs/common';
import { LoggerService } from './logger.service';

@Global()
@Module({
  providers: [LoggerService],
  exports: [LoggerService],
})
export class LoggerModule {}

Is there any way to somehow pass context on injection in service constructor and avoid execution of logger.setContext(context) in every service - instead just set it in LoggerService constructor?

Example usage now:

constructor(private logger: LoggerService) {
    this.logger.setContext(ClassName.name);
}

Expected usage:

constructor(private logger: LoggerService) {}

Solution

When you do private logger: LoggerService, there's no chance to make that .setContext(Service.name) call.

What you could do is something like:
@Logger(Service.name) private logger: LoggerService
