💅 FUNCTION-DELETE(3valkey) 💅

okay bestie, welcome to the Valkey Command Manual — this one's a little brutal but honestly iconic for it. it's function-delete, and yes it does exactly what it says on the tin 🫶

✨ NAME ✨

function-delete — Deletes a library and its functions.

🌸 SYNOPSIS 🌸

FUNCTION DELETE library-name

🦋 DESCRIPTION 🦋

So. You know how a library is like, a whole squad of functions living together? Yeah. This command deletes the library called library-name and every single function inside it. no survivors. no takebacks. it's giving spring cleaning but with zero mercy 💀

If the library doesn't exist, the server hits you with an error. so like, don't try to delete a ghost library, it will simply not work.

For more information please refer to valkey-functions-intro(7) — Introduction to Valkey Functions. go read it, it's lowkey required reading for the function girlies.

🍓 EXAMPLES 🍓

watch and learn, bestie:

127.0.0.1:6379> FUNCTION LOAD "#!lua name=mylib \n server.register_function('myfunc', function(keys, args) return 'hello' end)"
"mylib"
127.0.0.1:6379> FCALL myfunc 0
"hello"
127.0.0.1:6379> FUNCTION DELETE mylib
OK
127.0.0.1:6379> FCALL myfunc 0
(error) ERR Function not found

see that last bit? 😭 you deleted mylib, so myfunc is gone gone. the FCALL comes back with (error) ERR Function not found and honestly? that's just consequences. periodt.
