I've found this repo https://github.com/styppo/hamstr to get started with, and cloned it for testing.

Not sure if I will keep moving on this direction; today I was reading code of this other repo https://github.com/nbd-wtf/nostr-tools

The last one have low level tools for connecting to relays, what makes it easier (at least for me) to understand the initial steps.

I'm not too passionate about a particular stack, although things like Alpine.js and Svelte make my eyes shine a little =)... Hooowever I hate JS in general LOL kidding... or not
