Scala Web Services with Akka-HTTP and Data Streaming

Modern web applications require backend systems that can handle massive amounts of data without crashing or consuming excessive memory. Building reactive, stream-based APIs in Scala is one of the most effective ways to achieve this level of performance and resilience. This course provides a clear, text-based guide to constructing robust HTTP services that stream data efficiently from your databases to your clients. You will transition from writing basic web endpoints to designing non-blocking, asynchronous APIs that process data in chunks. By learning how to leverage streaming pipelines, you will prevent memory overhead and keep your applications responsive under heavy loads. What you'll learn: - Understand the core concepts of reactive streams, backpressure, and asynchronous web routing in Scala - Configure and build modular HTTP API routes using the Akka-HTTP routing DSL - Connect your web endpoints to database streams for efficient, memory-safe data retrieval - Apply stream transformation operations like grouping and filtering to process data on the fly - Structure your Scala project using clean architecture principles and modern build tools - Test your HTTP routes using native testing libraries to ensure reliability Starting with foundational web concepts and Scala-specific terminology, this course guides you step-by-step through setting up your environment, writing your first routes, and implementing advanced streaming patterns. Each concept is reinforced with clear explanations and practical code implementations that you can read and analyze at your own pace. This course is designed for backend developers, data engineers, and Scala beginners who want to build high-throughput web APIs. No prior experience with Akka-HTTP or reactive streaming is required, though a basic understanding of Scala syntax is helpful. Start building resilient, stream-driven Scala web services today.
