What you'll learn
What is GraphQL and how to implement GraphQL APIs using Spring for GraphQL and Springboot Framework
GraphQL Query, Mutation and event-based Subscriptions
GraphQL Custom Scalars and Directives
GraphQL Cursor Paginations
GraphQL Exception Handling
GraphQL Request and Response Interceptors
GraphQL Test cases for Query, Mutation and Subscription
Requirements
basic knowledge of Java Programming and Spring Framework, mostly Springboot architecture
Description
In this Course, you will learn from basics to advanced features of GraphQL using Spring for GraphQL with Springboot 3 framework.Earlier, you need to write more java codes of GraphQL-Java to implement query, mutation or subscription. After springboot version 2.7, Spring for GraphQL released, which helped developers immensely with its annotation based architecture. In this course, we will develop GraphQL microservice APIs using Springboot 3 and Spring for GraphQL framework.Now-a-days, GraphQL is gaining its popularity over REST apis. In my experience, I have seen many projects move towards GraphQL mostly because of its Query feature which retrieves data exactly what the client has requested for. In this course, I have extensively covered all the features of GraphQL Query including custom scalars, directives and paginations for this purpose.This course is mostly hands-on and java programming based, I have focused more on how to implement GraphQL services rather that on the theoretical aspects. This course covers GraphQL Query, Mutation, Subscription as well as advanced topics like extended scalars (using external jars), directives, cursor paginations etc. You will also learn about exception handlings and how to use interceptors. In any API development, writing unit test cases or integration test cases is a must, hence, you will learn that as well using Spring GraphQLTester apis.After completion of the course, you will be able to write complete GraphQL microservice applications using Spring framework with most its features including test cases.
