GraphQL Fundamentals: Designing and Implementing Modern APIs

Are you tired of over-fetching data with traditional REST APIs? GraphQL offers a powerful, modern solution for efficient data retrieval in complex applications. By the end of this course, you will have a solid foundation in the GraphQL specification, enabling you to design resilient schemas, implement powerful resolvers, and integrate GraphQL services into any application architecture. What you'll learn: * Understand the core concepts of the GraphQL specification, including types, fields, and the difference between queries and mutations. * Practice designing robust, scalable data schemas using a schema-first approach. * Implement powerful queries and mutations for fetching and modifying data effectively. * Apply best practices for handling data resolution, including optimizing performance and batching requests. * Configure basic security measures, such as input validation and rate limiting, for production-ready GraphQL endpoints. * Master the GraphQL ecosystem tools necessary for testing and introspection. This course begins with foundational terminology and the architecture of a GraphQL service. We then move into practical implementation, covering schema definition, resolver logic, and integrating with underlying data sources through written examples and exercises. This course is designed for beginner developers and engineers who are familiar with basic programming concepts but new to GraphQL. No prior experience with API design or GraphQL is required.
