Hello! could someone advice me a good book where Ring and Compojure are in detail please 😉 ?

I'd say your best bet is online documentation.

Perhaps Web Development with Clojure has something useful too

The "Web Development with Clojure" book uses reitit for routing. It doesn't mention compojure anywhere (I just searched the PDF of the 3rd edition).

I thought about the second edition - that one has some ring and compojure, especially in Chapter 2, Although it's a bit outdated I'd say that the core concepts stay same

Ah yes, I think I remember Dmitri saying that they switched to reitit for the 3rd ed so it would make sense that the 2d ed still uses Compojure.
