Asynchronous Web Development with Ratpack

Modern web applications demand high throughput and low latency. Ratpack provides a powerful, lightweight toolkit designed specifically for high-performance asynchronous HTTP services without the overhead of traditional frameworks. This course helps you grasp the core concepts of non-blocking programming and apply them to real-world web development. You will start by mastering foundational asynchronous principles, understanding event loops, and setting up your development environment. From there, you will explore how to structure applications, handle routing, manage asynchronous data flow, and integrate modern database drivers. By the end of this course, you will be able to write clean, reactive, and highly scalable backend services. What you'll learn: - Understand the core principles of asynchronous and non-blocking I/O programming - Configure Ratpack applications using Gradle and modern Java or Groovy syntax - Design efficient routing chains and handle HTTP requests and responses - Manage asynchronous execution flows using Ratpack's Promise API - Integrate modern reactive database clients and handle data persistence - Implement unit and integration testing patterns for asynchronous handlers We begin with essential terminology, basic reactive concepts, and architectural definitions before moving into hands-on configuration, routing, and database integration. The learning journey is structured logically to build your confidence step-by-step through written explanations and clear code examples. This course is designed for backend developers, software engineers, and Java or Groovy programmers who want to learn asynchronous web development. No prior experience with Ratpack or reactive programming is required.
