Building RSocket Clients with Spring Boot

Modern application development requires fast, resilient, and bi-directional communication channels. RSocket offers a powerful alternative to traditional HTTP, enabling reactive, multiplexed, and duplex messaging over a single connection. This text-based course guides you through the fundamental concepts of RSocket and shows you how to implement a fully functional client using Spring Boot and Java. You will start with the core architecture of reactive streams, understanding how backpressure works to prevent system overload. From there, you will learn to set up your development environment, configure dependencies with Maven, and establish stable connections to RSocket responders. Through clear written explanations and practical code examples, you will master the four interaction models that make RSocket so versatile. What you'll learn: - Understand the core principles of RSocket, reactive streams, and backpressure - Configure a Spring Boot client project from scratch using Maven and Java - Establish secure and resilient connections to RSocket servers - Implement Request-Response and Fire-and-Forget communication patterns - Build Request-Stream and Channel patterns for real-time data streaming - Apply modern reactive programming practices using Project Reactor This course is structured to take you from foundational networking concepts to writing clean, production-ready client code. You will explore step-by-step configuration files, message mapping strategies, and error-handling mechanisms that ensure system reliability. This course is designed for Java developers, backend engineers, and software architecture beginners who want to move beyond traditional REST APIs. No prior experience with RSocket is required, though a basic understanding of Spring Boot and Java is helpful.
