Description

This course,  is a comprehensive guide, designed for developers looking to master the art of creating efficient, modern APIs using GraphQL in conjunction with Spring Boot, one of the most popular frameworks in the Java ecosystem. The course delves deep into the intricacies of GraphQL, a powerful query language for APIs, and demonstrates its integration with Spring Boot 3, using JDK 17. Participants will learn to design, build, and manage robust APIs, gaining hands-on experience through a practical project-based approach.The significance of this topic lies in the growing demand for efficient, scalable, and flexible APIs in the digital landscape. GraphQL offers a more efficient alternative to traditional REST APIs by allowing clients to request exactly what they need, reducing over-fetching of data. This course addresses the common challenges faced in API development, such as handling complex UI requirements, optimizing performance, and ensuring effective error handling. By focusing on GraphQL with Spring Boot, the course equips developers with the skills to build high-performance, scalable APIs that are well-suited for modern web and mobile applications. Participants will emerge with a strong foundation in GraphQL, enhanced Java skills, and the confidence to apply these technologies in real-world scenarios.Course Learning Objectives:The primary learning objectives of the course is to equip participants with a thorough understanding of GraphQL as a powerful API query language and its effective integration with Spring Boot.By the end of the course, attendees will be adept at building and deploying efficient, scalable, and robust GraphQL APIs using Spring Boot and JDK 17, ready to tackle real-world challenges in modern web development.Complete a real-world project assignment : mastering GraphQL schema design and management, delving into advanced GraphQL features, enhancing Java 17 object-oriented programming skills, becoming proficient in GraphQL-specific error handling, and learning to implement data validation mechanisms within GraphQL queries and mutations. Gain practical, real-world experience in applying GraphQL and Java 17, preparing for advanced tasks in modern web and API development environments.
