Tech Stack

In real world projects I would never define the list of tech stack before understanding the requirements and the constraints of the projects. I would also try to keep the stack simple, short and boring. See my own blog post about it.

However, this project is a playground to test and learn new technologies so I can risk it and any technology I feel like. Here I am listing some of the technologies I am planning to use in this project and some of the patterns I want to try out. This is a sort of wishlist. The list will keep growing and I will not be able to use/learn everything listed there.

I am marking with ✔️ the technologies/approaches I am using and with 🚧 the ones I started to add but are still not functional.
