Provide an ergonomic way to set custom logger prefix
Is there an existing issue that is already proposing this?
- [X] I have searched the existing issues
Is your feature request related to a problem? Please describe it
I have multiple apps using Nestjs monorepo setup. In that case if I run all apps at the same time it would be great being able easily to differentiate the log output. By default the console output starts with [Nest]... as per this line https://github.com/nestjs/nest/blob/master/packages/common/services/console-logger.service.ts#L226
In order to change this behavior you had to provide a custom logger or use another logging library. The pain here is that you must repeat that same action for each app...
Describe the solution you'd like
However I believe that it would be way easier to being able to set a custom prefix out of the box e.g app.setLoggerPrefix('my-app-name')
Teachability, documentation, adoption, migration strategy
What is the motivation / use case for changing the behavior?

Hi @kuncevic Looks a good idea! Additionally, it would be worth discussing the message format. Right now, the messages are displayed like this:
[Nest] 16680 - 15/08/2024, 23:30:49 LOG [NestApplication] Nest application successfully started +3ms
[Nest] 16680 - 15/08/2024, 23:30:49 LOG Hello world!
Do you have any ideia how to display this prefix message?
One suggestion could be:
[Nest] my-app-name 16680 - 15/08/2024, 23:30:49 LOG [NestApplication] Nest application successfully started +3ms
[Nest] my-app-name 16680 - 15/08/2024, 23:30:49 LOG Hello world!
another suggestion:
[Nest] 16680 - 15/08/2024, 23:30:49 LOG [NestApplication] [my-app-name] Nest application successfully started +3ms
[Nest] 16680 - 15/08/2024, 23:30:49 LOG [my-app-name] Hello world!
Do you have any other suggestions?
can't we achieve this already with https://docs.nestjs.com/techniques/logger#extend-built-in-logger ?
@WillianAgostini Ideally, I would see it as an exposed config option that you just stick whatever you want into, not the way it is done atm, that required a lot of boilerplate to fix. Will have to do that for each Nest project in my monorepo....painful.
