About this course

Building reliable APIs requires effective error management, especially when handling data modifications through mutations. This course equips you with the foundational knowledge and practical techniques to design and implement comprehensive error handling for GraphQL mutations within Elixir applications using Absinthe. You will transform your API interactions by providing clear, standardized, and user-friendly error messages. What you'll learn: * Understand the fundamentals of GraphQL mutations and their role in data manipulation. * Learn how Absinthe handles errors by default and how to customize this behavior. * Implement custom error types and codes for specific business logic failures. * Apply strategies for reporting detailed and actionable error messages to GraphQL clients. * Practice integrating error handling with Elixir's pattern matching and with expressions for cleaner code. * Configure structured error responses that align with modern API design principles. The course begins with an introduction to GraphQL mutations and Absinthe, then progresses through various error handling patterns, from basic techniques to advanced custom error structures. You will then apply these concepts to build robust and user-friendly API responses. This course is designed for beginner Elixir developers who want to build robust GraphQL APIs. No prior experience with GraphQL or Absinthe is required, just a basic understanding of Elixir programming. Enroll now to build more resilient and user-friendly GraphQL APIs.
