Building GraphQL APIs with Rails

Modern front-end applications require flexible, efficient APIs that deliver exactly the data they need without over-fetching. Traditional REST APIs can become cumbersome to maintain as your client applications grow and evolve. This text-based course guides you through integrating GraphQL into your Rails applications. You will transition from standard REST endpoints to a single, powerful GraphQL schema, enabling seamless communication between your Ruby on Rails backend and any front-end client. What you'll learn: - Understand the core concepts of GraphQL, including queries, mutations, and schemas. - Configure a Rails application to expose a clean, type-safe GraphQL endpoint. - Implement efficient data fetching using modern patterns like DataLoader to prevent N+1 query performance issues. - Create secure mutations to create, update, and delete data safely. - Apply robust authentication and authorization strategies to protect sensitive API fields. - Write structured tests for your GraphQL queries and mutations to ensure API stability. The course begins with foundational definitions and setup, establishing a solid understanding of GraphQL types and schemas. You will then progress through practical written guides and code snippets to build query resolvers, handle mutations, optimize database performance, and secure your API. This course is designed for web developers and Rails enthusiasts who want to adopt GraphQL. A basic familiarity with Ruby on Rails is helpful, but no prior experience with GraphQL is required.
