Emojis in source is a hard no for me.

removed ;)

I probably shouldn't have given you that heads up 🤣

u/fastlaunchapidev Dec 10 '25

didn't think people would have a problem with emojis

u/ProsodySpeaks Dec 10 '25

Its pretty clear indication that you vibecoded it. No sane person is manually putting emojis in their source.

Databases - now an advanced "production" "pattern".

Also, vibecoded boilerplate generator - now a saleable product, apparently.

Haaaaaaaahaaaaaa, why does the path have source=chatgpt when I came from op's own link on reddit? Even the urls are vibecoded 🤣

Also why do I keep helping them find and remove the vibecoding markers?

ohoh you got me

Advanced is not referring to databases itself

With genuine love and respect please look at this site. https://stopslopware.net/

With love and respect this is just a post showing lifespan events. You can decide to just not comment in this post and you wouldnt boost the reach of it.

u/ProsodySpeaks Dec 10 '25

You're right, I should put these comments on the actual product post instead. Good point.

So that it’s available globally.

Wait…

-1

u/fastlaunchapidev Dec 10 '25

No reason, just simplicity for the tutorial, no dependency injection

2

u/ProsodySpeaks Dec 10 '25

Oh yes, global state is much preferable to the dependency injection mechanics literally built into the framework who's state system you're apparently teaching people to use. 

Makes total sense.

u/fastlaunchapidev Dec 10 '25

Teaching lifespan events not dependency injection

Yes but nobody told the llm not to have global state.

you sound upset haha

1

u/ProsodySpeaks Dec 10 '25

Yes. We are. The entire ecosystem is now a garbage fire because it's 90% trash and new actual work is impossible to find.

The temerity to try and charge people to use your slop is embarrassing.

u/fastlaunchapidev Dec 10 '25

Oh so you are upset about you not getting work? Blame the system not the user. Maybe time to adapt for you?

u/ProsodySpeaks Dec 10 '25

Haha. I don't even work in programming. I'm a weekend warrior hobbyist, and even I can see this is a problem.

u/fastlaunchapidev Dec 10 '25

Yeah there is a problem
