Nonestack is a growing library of in-depth Spring Boot tutorials — from your first application to authorization servers, JPA and REST clients. It's free, and every guide is built from a repository you can run yourself.
The tutorial you read is the README of a real, buildable project. Clone it, run it, break it — the code and the words never drift apart.
Each guide solves one concrete task end to end — the smallest complete app that demonstrates the idea, with the reasoning shown, not just the final file.
Guides track the current Spring release — no deprecated WebSecurityConfigurerAdapter, no Spring Boot 2 leftovers. When the framework moves, the repos and the articles move with it.
I'm Djamel Eddine Korei, a software engineer working with the Spring ecosystem. I write Nonestack to keep my own notes honest — if I can't reduce a topic to a small project that compiles and runs, I don't understand it well enough to publish it yet.
