Reactive Web Applications with Spring WebFlux

Modern web applications must handle massive numbers of concurrent requests without consuming excessive system resources, making traditional blocking architectures a bottleneck. Reactive programming solves this by enabling non-blocking, event-driven data streams that utilize hardware efficiently. This text-based course guides you from the fundamental concepts of asynchronous streams to building fully responsive, resilient, and scalable backend services. What you'll learn: - Understand the core principles of Project Reactor, including Mono, Flux, and backpressure management. - Build non-blocking REST APIs using both annotation-based and functional routing models. - Configure reactive data access using modern R2DBC database connectors. - Practice writing reliable tests for asynchronous streams using StepVerifier. - Apply modern observability and tracing techniques to monitor reactive execution pipelines. You will begin with essential reactive terminology and foundational architectural concepts before moving on to practical API development and database integration. Through clear written explanations and structured code walk-throughs, you will master the reactive paradigm step-by-step. This course is designed for Java developers looking to transition into reactive web development, with no prior Spring WebFlux experience required. Start reading today to build high-performance, non-blocking web applications.
