Building PostgreSQL APIs with Elixir and Ecto

Modern web applications demand fast, reliable, and concurrent data access. Elixir combined with the Ecto database wrapper provides an exceptionally powerful platform for building highly performant APIs backed by SQL databases. This text-based course guides you through the process of setting up database connections, designing schemas, and exposing clean API endpoints for data persistence. You will start with core database concepts, understanding how Elixir interacts with SQL, and setting up your first Ecto repository. From there, you will progress to writing queries, managing migrations, and structuring your application for clean separation of concerns. What you'll learn: - Understand the fundamentals of Elixir database integration and the Ecto architecture - Configure secure connections to a PostgreSQL database using modern environment variables - Design robust database schemas and handle data validation with Ecto changesets - Write efficient SQL queries and manage complex relationships like one-to-many and many-to-many - Implement structured database migrations to evolve your schema safely over time - Build clean, RESTful API endpoints that expose database operations to external clients This course is structured to take you from foundational database definitions to a fully functional, queryable API. You will learn through clear written explanations, conceptual breakdowns, and practical code examples. This course is designed for beginners to Elixir data access and developers looking to transition from other backend frameworks. No prior database experience in Elixir is required, though a basic understanding of Elixir syntax is helpful. Start reading today to build reliable, database-driven Elixir applications.
