GraphQL Microservices with Spring Boot: A Practical Foundation

Modern backend development demands flexible and efficient APIs that allow clients to request exactly the data they need. Transitioning from traditional REST to GraphQL using Spring Boot is one of the most valuable skills you can acquire as a Java developer today. This text-based course guides you from foundational API concepts to deploying your own structured microservices. You will gain a solid understanding of how GraphQL operates under the hood, learn to model data effectively, and construct robust APIs using modern Spring Boot conventions. What you'll learn: - Understand the core differences between REST and GraphQL, including queries, mutations, and schemas. - Configure a Spring Boot project integrated with modern Spring GraphQL features. - Design schema files and map them to Java data models using modern features like Records. - Create efficient data fetchers and resolvers to handle complex query operations. - Apply testing best practices using specialized GraphQL testing utilities. - Build a structured GraphQL microservice from the ground up. You will start by mastering the essential terminology and architectural patterns of GraphQL before moving on to step-by-step code implementations. Through clear written explanations and structured code analysis, you will develop a complete, functional microservice. This course is designed for Java developers new to GraphQL or those looking to transition from REST APIs to modern query-based service architectures. No prior GraphQL experience is required.
