Spring WebFlux: Build Scalable Reactive Web Apps

О курсе

Did you know that reactive programming is transforming how developers build responsive and resilient systems? From fintech to real-time dashboards and microservices, companies are turning to Project Reactor, WebClient, and functional routing to build efficient, event-driven backends. If you're looking to future-proof your Spring knowledge and deliver faster APIs, this course is for you.  Hey there, Java developers and backend architects! Ready to take your Spring skills to the next level and build apps that don’t break under load? Get ready for a deep dive into Spring WebFlux—because modern web applications aren’t just about business logic anymore. They’re about speed, scalability, and non-blocking performance that can handle thousands of concurrent users.  I get it—you’ve spent years mastering Spring MVC, working with servlets, and building blocking REST endpoints. Switching to a whole new reactive model can feel like stepping into unknown territory. But trust me, WebFlux is not just another buzzword—it’s a game-changer, and I’m here to make it approachable and practical.  This course takes a hands-on, demo-driven approach to mastering Spring WebFlux. You’ll start by exploring the core concepts of reactive programming, learning to think in streams with Mono and Flux, and using operators like map, flatMap, and zip to build asynchronous flows. Then we’ll build out REST APIs using functional routing, implement server-sent events for streaming data, and use WebClient for reactive HTTP calls and error handling.  This course is designed for Java developers and backend engineers who are ready to move beyond traditional Spring MVC and embrace the reactive paradigm. Whether you're building microservices, real-time dashboards, or event-driven systems, you'll gain the tools to develop highly responsive and scalable backends using Spring WebFlux. It's also ideal for software architects and tech leads tasked with modernizing legacy applications and adopting reactive design patterns to meet the demands of cloud-native architectures. To succeed in this course, learners should have solid experience with Java, particularly with streams and lambda expressions. A strong understanding of Spring Boot fundamentals—including controllers, services, and dependency injection—is essential. While prior exposure to REST API development is expected, only a basic grasp of asynchronous programming concepts is needed, making this course accessible to those transitioning into the reactive programming world. By the end of this course, learners will be able to clearly articulate the principles of reactive programming and apply them in the Spring WebFlux ecosystem. They will build modular and reactive REST APIs using functional routing, integrate Reactive MongoDB for real-time data streaming, and master techniques to identify and eliminate blocking calls to enhance application performance. These skills will empower them to design resilient, cloud-scale applications ready for modern deployment environments.
