Thanks, this is reassuring. Yeah I don’t really know what I’m doing with the headers but trying my best to be as restrictive as possible. I think I’m still doing something wrong with the headers because I can’t seem to connect to the backend when the fronting is deployed.

Yeah I’m super paranoid about what I’m exposing, I made sure that there are no environment variables or secrets exposed.

Thanks! This is something I had no idea could be an issue. I just started standing up all the dummy functions for the different layers so I’ll take a step back now and review the resources you pointed me at. Also, in the Poem docs I don’t see them using async functions either. I’m very glad I asked.

Thanks! One of the reasons for choosing Rust was actually concurrency. So I’m building a bunch of endpoints that connect with some microservices and I expect to have many simultaneous requests. I’m honestly not like super senior but for the Python backends we’ve been building we always made everything asynchronous so I kinda got the impression that that would be necessary for my use cases. Should I also be careful with async functions when using Poem?
