GraphQL API Engineering: Schema Design, Security, and Deployment

Building functional APIs requires more than just writing basic queries; it demands robust architecture, reliable security, and seamless deployment workflows. This text-based course teaches you how to construct professional GraphQL services from the ground up. You will transition from understanding basic GraphQL concepts to designing resilient schemas, securing your endpoints against malicious queries, and deploying your APIs to modern cloud environments. What you'll learn: - Understand core GraphQL concepts, including types, queries, mutations, and resolvers. - Design clean, scalable schemas using industry-standard naming conventions and structural patterns. - Secure your APIs by implementing query depth limiting, rate limiting, and authentication. - Implement real-time capabilities using GraphQL subscriptions and modern transport protocols. - Deploy your GraphQL services to cloud platforms using containerized workflows and modern deployment patterns. - Explore modern federation patterns to scale your graph across multiple microservices. The course begins with foundational terminology and schema design principles before guiding you through security configurations and cloud deployment strategies. Through clear text explanations and practical code examples, you will build a solid architectural foundation. This course is designed for backend developers, software engineers, and web development enthusiasts who are new to GraphQL or want to transition from REST APIs. No prior GraphQL experience is required. Start reading today to design and deploy secure, production-grade GraphQL APIs.
