Scala HTTP Services with Akka-HTTP and PostgreSQL

Building reliable and performant web services requires a solid understanding of how backend APIs communicate with relational databases. This text-based course guides you through the process of connecting a Scala application to a PostgreSQL database using the Akka-HTTP framework. You will learn to handle HTTP requests, perform CRUD operations, and structure your code for real-world projects. By completing this course, you will be able to confidently construct and interact with database-backed Scala APIs. You will understand how to manage data flow from client requests down to the database layer and back. What you'll learn: - Understand the core principles of Scala HTTP routing and request handling - Configure secure and efficient connections to a PostgreSQL database - Build endpoints to create, retrieve, update, and delete database records - Apply modern Scala patterns, including type safety and asynchronous execution - Parse JSON payloads and handle errors gracefully within your routes - Structure your backend code using clean architectural layers We begin with foundational concepts, establishing essential terminology and database connection basics. From there, you will read through step-by-step implementation patterns, exploring how to write clean database queries and map them to HTTP endpoints. Each concept is reinforced with clear, written code examples and architectural explanations. This course is designed for beginner backend developers and software engineers who have a basic familiarity with Scala and want to learn database-driven web development. No advanced systems architecture experience is required. Start reading today to master backend Scala development and build robust database APIs.
