Ok genuine question, since I feel like I’m using logs wrong:
How much stuff do you log in the server? I’ve only ever seen devs log basic high-level stuff. But to actually debug something, you need way more information.
I’ve tried sticking debug-level logs that log all sorts of business logic. Pretty much recreating what you would do with console.log when trying to isolate an issue locally.
But then you have your code permanently littered with debug log lines! It makes things… ugly!!
If you NEED detailed logging, do you just deal with the uglified code? Or is there a better solution? Decorators that logs parameters and such automatically??
> how else would one reproduce a bug? in production?
I don't think they meant "either" "or". I think they meant that you should not solely rely on reproducing issues locally. If you have good logging, many times, the logs would make it apparent where the issue is. When that fails, then you resort to reproducing the issue locally.
But if an app developer never adds any logs, they would be forced to reproducing the issue locally every single time which is counter productive.
So it isn't either logs or reproduce locally. It is add logs and read logs. But also reproduce locally when you really have to.
It just takes a lot less time to reproduce if you have some logging in production... and some people seem to believe that's not needed.
And if you have logs, you may not need to reproduce it because said logs give you all the info you need.
Disclaimer: circumstances may vary. A bug is a bug is a bug and you may solve it by reading one log line, or you may spend a week with a debugger in your development environment and it will still crash in production when you deploy the fix.
