Building GraphQL APIs with Elixir and Absinthe

Modern web applications demand efficient, flexible, and type-safe APIs that can fetch exactly the data they need in a single request. This text-based course guides you through the process of building robust GraphQL APIs using Elixir and its premier GraphQL toolkit, Absinthe. You will start with the absolute fundamentals of the Elixir ecosystem, ensuring you understand how OTP applications run before diving into API design. Through clear explanations and structured code walk-throughs, you will progress from initial project setup to deploying a fully functional, schema-driven API. You will explore how to model your data, construct queries and mutations, and connect your API safely to a database. What you'll learn: - Understand the core principles of GraphQL and how they map to Elixir and Absinthe concepts - Configure an Elixir project with database migrations and schema definitions - Write clean Absinthe schemas, queries, and mutations to handle complex data relationships - Implement efficient data loading patterns to prevent common database performance bottlenecks - Secure your API using modern authentication and context-based authorization patterns - Test your GraphQL endpoints thoroughly using robust unit and integration testing strategies This course begins with foundational concepts, guiding you step-by-step through configuration, schema design, and database integration. It is designed specifically for developers who are new to GraphQL or Elixir, requiring only a basic understanding of programming logic. Start reading today to build fast, scalable, and resilient APIs.
