GraphQL APIs with Absinthe and Elixir for Beginners

Building modern, efficient web applications requires a robust API layer that can fetch exactly the data your clients need without over-fetching. GraphQL provides the perfect query language for this task, and when paired with Elixir's high-performance concurrency model and the Absinthe framework, you get an incredibly resilient API backend. This text-based course guides you from absolute beginner to confidently structuring and querying your own APIs. You will transition from understanding basic web communication to writing structured schemas and handling complex queries. By reading through real-world scenarios and analyzing clear code snippets, you will grasp how Elixir and Absinthe work together to resolve data efficiently. What you'll learn: - Understand the core concepts of GraphQL, including schemas, types, queries, and mutations - Configure the Absinthe framework within a standard Elixir application - Write clean resolver functions to fetch and manipulate database records safely - Implement modern API best practices, including basic security, authentication, and error handling - Practice structuring nested queries and managing relational data loading efficiently This course starts with foundational definitions, comparing REST and GraphQL, before diving into Elixir setup, schema design, and resolver implementation. You will explore practical code patterns and learn to structure production-ready APIs step-by-step. This course is designed for beginner backend developers, Elixir enthusiasts, and web developers looking to add GraphQL to their toolkit. No prior experience with Absinthe or GraphQL is required, though a basic familiarity with Elixir syntax is helpful. Start reading today to master modern API development with Elixir and Absinthe.
