Guidelines for working with Appwrite with ESP8266 on Arduino without SDK

I wanna create this support ticket to keep track of a work regarding Arduino specific examples which could lead for creating an SDK for IoT devices like ESP8266 and ESP32. I would really appreciate it if you point me if I am working in the right direction or missing something or doing something which should be done differently.

I think first of all I should be working by creating a simple anonymous user login and REST API based db handling.

Have you read through the SDK generator repo and, in particular, the contributing guide? https://github.com/appwrite/sdk-generator/blob/master/CONTRIBUTING.md
