📚 Course Overview

This course provides both theory and hands-on coding to master Reactive Programming and Reactive RESTful APIs using Spring WebFlux.
You will:
Understand Reactive Programming concepts
Write reactive code with Spring WebFlux and databases (MongoDB)
Build Reactive REST APIs (annotated and functional style)
Handle errors and exceptions in reactive applications
Stream real-time data using Server-Sent Events (SSE)

📝 What You’ll Learn

1️⃣ Introduction & Motivation
Why Reactive Programming?

Need for reactive programming
Limitations of Spring MVC
Spring MVC concurrency model
What is Reactive Programming?
Basics with simple examples
Introduction to Reactive Streams specification
Overview of popular Reactive libraries

2️⃣ Project Reactor

Fundamentals of Project Reactor
Reactive types: Flux and Mono
Hands-on examples with Flux & Mono
JUnit testing with Flux & Mono
Operators in Reactor

3️⃣ Spring WebFlux API Development

🌟 Annotated Controllers
Build first non-blocking REST API
Return Flux / Mono from endpoints
JUnit tests with WebTestClient

🌟 Functional Web Module
Build non-blocking API with RouterFunction and HandlerFunction
JUnit tests with WebTestClient

🌟 Under the Hood
Spring WebFlux & Netty execution model
Netty concepts: Channel, EventLoop

💾 Reactive Programming with Databases
Configure reactive MongoDB
Define MongoDB Item document
Setup reactive MongoDB adapter
JUnit tests for reactive repository

🔧 CRUD API Development
Build Item CRUD API using @RestController
Build Item CRUD API using Functional Web
Automated tests using WebTestClient

🌐 Reactive Client
Build non-blocking client using WebClient
Perform GET, POST, PUT, DELETE
Techniques with exchange() and retrieve()
Handle exceptions in WebClient

⚠️ Exception Handling
RestController
Handle errors with @ExceptionHandler & @ControllerAdvice
JUnit tests for exception scenarios
Functional Web
Handle errors with WebExceptionHandler
JUnit tests for exception scenarios
WebClient
Handle exceptions with exchange() & retrieve()

📡 Streaming Real-Time Data (SSE)
Build streaming endpoint using SSE
Use tailable cursors & capped collections in MongoDB
Use @Tailable for non-blocking streaming
Write automated tests for SSE endpoints},
