Show HN: Building your first ASGI framework – step-by-step lessons

I am writing a series of lessons on building an ASGI framework from scratch. The goal is to develop a deeper understand of how frameworks like FastAPI and Starlette work.

A strong motivation for doing this is because - I have been using AI to write code lately. I prompt, I get code, it works. But somewhere along the way I see I stopped caring about what is actually happening. So, this is an attempt to think beyond prompts and build deeper mental models of things we use in our day to day lives. I am not sure about the usefulness of this but I believe there are good lessons to be learnt doing this.

The series works more as a follow along where each lesson builds on the previous one. By the end, you will have built something similar to Starlette - and actually understand how it works.
