• A NestJS module to handle customized logging for generator-nest-microservices yeoman template

How to use

• install package with npm i -S nest-microservices-logger
• Register the LoggerModule to your feature modules:

@Module({})
export class AppModule {
  static register(config: ConfigOptions): DynamicModule {
    return {
      module: AppModule,
      imports: [
        LoggerModule.register({ appName: 'my-app-name' }),

  }
}
