Project Reactor Hands-On Learning

Welcome to my hands-on learning repository for Project Reactor in Java! This repository contains my journey of exploring reactive programming concepts through practical examples and exercises using Project Reactor.

📌 About

This repository is my personal learning space where I experiment with Project Reactor, a foundational library for building reactive applications on the JVM. Here, I document my progress through various reactive programming concepts, from basic to advanced.

🚀 What's Inside

• Basic reactive streams with Flux and Mono
• Operators and transformations
• Backpressure handling
• Error handling strategies
• Testing reactive streams
• Advanced topics like combining publishers, hot vs cold publishers, etc.
• Practical examples and use cases

🛠️ Prerequisites

To work with the examples in this repository, you'll need:

• Java 11 or higher
• Maven 3.6+
• Basic understanding of Java and functional programming concepts
• (Optional) IDE with Java support (IntelliJ IDEA recommended)

⚙️ Setup

1. Clone the repository:

   git clone https://github.com/abhishek-shrestha224/java-reactive-programming.git
   cd project-reactor-learning

2. Build the project:

   ./mvnw clean install

📚 Learning Path

The repository is organized by concepts, with each having its own package and examples:

1. Core Concepts

   • Hello World with Reactor
   • Flux vs Mono
   • Subscribing to Publishers

2. Operators

   • Transformation operators (map, flatMap)
   • Filtering operators (filter, take, skip)
   • Combining operators (merge, zip, concat)

3. Advanced Topics

   • Backpressure strategies
   • Schedulers and threading
   • Hot vs Cold Publishers
   • Testing with StepVerifier

🤝 Contributing

While this is primarily a personal learning repository, I welcome suggestions, corrections, or additional examples that could help others learn Project Reactor. Feel free to open issues or pull requests!
