About this course

Many developers struggle with designing GraphQL APIs that can efficiently query different types of data without creating rigid schemas or over-fetching. This course equips you with the knowledge to leverage GraphQL's powerful abstract types in Elixir with Absinthe, enabling you to build highly flexible and scalable APIs capable of handling complex data structures and dynamic search capabilities. What you'll learn: * Understand the core concepts of GraphQL, its schema definition language, and type system fundamentals. * Learn how to define and implement GraphQL interfaces and union types using Absinthe in Elixir. * Apply abstract types to design flexible query and mutation operations for diverse data sources. * Practice building dynamic search features that can return and resolve multiple underlying data types. * Configure Absinthe resolvers to work seamlessly with complex abstract type resolution logic. * Incorporate basic error handling and input validation patterns into your Absinthe GraphQL API. * Practice testing GraphQL schemas and resolvers in Elixir to ensure API robustness. This course begins with foundational GraphQL and Elixir concepts before diving into the practical implementation of abstract types, guiding you through building and refining flexible API components step-by-step. This course is for beginners in Elixir and GraphQL development who want to build robust and adaptable API solutions. No prior experience with GraphQL or Absinthe is required.
