BunyanLogger extending built in Logger

Looking to use the BunyanLogger in this context: https://docs.nestjs.com/techniques/logger#injecting-a-custom-logger

Where I can do setContext, which seems to be provided by the built in Logger. Could the BunyanLogger extend that to provide this, or is it more involved?

Looks like BunyanLogger takes a context as the second param to log, but in a class scenario it’s tedious to have to set that every time in the class.

Hey @knownasilya. if you want to add more context in your logs. you can try using the extraFields arg.

    extraFields: {
        yourCustomContext:'ANY STRING',
        environment,
        version: packageBody.version,
      }

And inside of any service, you can use:

class MyService {
  private logger = new Logger(MyService.name);


  getData(args){
     this.logger.log("Heello") // here the log will have as context the Service name and all the extra fields.
  } 

}

Yes. I used it in the main directly and then I used it separately as a service.
