[argparse] Don't instantiate Config on import Robyn

[gastmaier]

Hi, I noticed that argparse is deeply associated in Config():

https://github.com/sparckles/Robyn/blob/main/robyn/argument_parser.py#L6-L87

And that Config.init is called many times, at least from:

caller name: WebSocket
caller name: <module>
caller name: BaseRobyn
caller name: SubRouter

at import Robyn, and global defined at

https://github.com/sparckles/Robyn/blob/main/robyn/__init__.py#L58

I would like to request some reconsideration/rework on allowing robyn apps without the default argparse setup, instead, let the user cli pass the appropriate parameters.

As is, my understanding is that it is rather difficult achieve a

my_custom_cli --help

that doesn't output robyn own help

Thanks,

@gastmaier , what would you recommend instead?

Hi @sansyrox added my recommendation to #1252 for Config(). There are other classes that are initialized at other classes definitions.
My pr got attacked by the skynet tho.
