Secure GraphQL APIs with Absinthe Authentication

Building a modern API requires robust security, especially when managing sensitive user data. This written course guides you through securing your Elixir GraphQL APIs by establishing a solid authentication flow. You will start by understanding foundational security concepts and GraphQL schemas before diving into practical implementation. Throughout this course, you will transition from a basic API setup to a fully secured system that safely handles user credentials and restricts access based on permissions. You will learn to write clean, secure code that integrates seamlessly with Elixir's concurrent ecosystem. What you'll learn: - Understand the core principles of API security and GraphQL authentication flows - Implement a secure login mutation using Absinthe and Elixir - Generate and validate JSON Web Tokens (JWT) for stateless authentication - Manage user roles and enforce authorization rules across different schema fields - Write unit tests to verify your authentication resolvers and secure context - Apply modern security best practices to protect your API from common vulnerabilities The course begins with essential terminology, security definitions, and architecture basics. From there, you will explore step-by-step written explanations and code examples to build, test, and refine your authentication system. This course is designed for beginner to intermediate Elixir developers who want to secure their Absinthe APIs. No prior experience with GraphQL authentication is required.
