## What it is
A sandbox repository and accompanying online book of runnable sample code demonstrating reactive programming with Spring Framework 7, Spring Boot 4, WebFlux, Reactor, and the broader reactive Spring ecosystem. It includes dozens of small example projects covering reactive data access (R2DBC, MongoDB, Redis, Cassandra), security, sessions, and alternative reactive libraries like RxJava.

## Use cases
- learn spring webflux reactive programming
- find spring boot reactive sample code
- compare reactor vs rxjava in spring
- example of spring data r2dbc usage
- learn reactive spring security configuration
- reference for spring boot 4 reactive stack
- understand reactive streams in spring framework

## When to choose
- you are learning or teaching reactive Spring development and want runnable examples
- you need up-to-date sample code for Spring Boot 4 / Spring Framework 7 reactive features
- you want to compare reactive data access options like R2DBC, MongoDB reactive, and Cassandra in Spring

## When to avoid
- you need a production-ready starter template or framework rather than educational samples
- your project uses the servlet-based blocking Spring MVC stack
- you need a single cohesive application instead of many independent demo modules
