You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use rails new first to generate all of the boilerplate files necessary.
Create an app in the current directory with rails new .
Use Tailwind CSS for styling. Use --css tailwind as an option on the rails new call to do this automatically.
Use Ruby 3.2+ and Rails 8.0+ practices.
Use the default Minitest approach for testing, do not use RSpec.
Default to using SQLite in development. rails new will do this automatically but take care if you write any custom SQL that it is SQLite compatible.
An app can be built with a devcontainer such as rails new myapp --devcontainer but only do this if requested directly.
Rails apps have a lot of directories to consider, such as app, config, db, etc.
Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.

Project Reactor: From Zero to Hero

In this series of pages, I will discuss project reactor and reactive programming from basic concepts to reactor internal implementation details. This discussion is based on the official reference documentation, the java-doc, talks by maintainers of reactor e.g. at the spring I/O and other distributed material, and should summarise and connect all this information. It should complement the official reference documentation and java-doc. Although the name says "from zero to hero", basic knowledge about the library is advised to fully benefit from it.

As a short disclaimer, I am a professional software engineer with some years of experience in using reactor, but not a maintainer or creator of the library. Information and knowledge in this post are based on the official documentation and talks, but I cannot exclude misconceptions on my side.
