Description
***** Some Reviews From Students *****
best course on graphql. learned a lot.
learning in simple words and explained very well. thanks
A very good introductory course to learn GraphQL from scratch and implementing the backend in Java using Spring.
Very informative. Easy concept explanations and equally well practicals.
In this course you are going to learn to GraphQL With Spring Boot and Spring Data JPA.
Now a days Spring framework is widely used among Java Developers and specifically Spring Boot is in high demand to develop REST APIs.
The problem with REST APIs is that it is giving fixed response in the format of the JSON ( JavaScript Object Notation ). So there comes GraphQL in picture. GraphQL provides flexibility that in request itself we can ask which fields we want in response and it populates only those fields.
In simple words we can say select * query in SQL database is like REST API while ability to provide columns (fields) with query and to return only those fields is GraphQL.
GraphQL boosts performance of your application and it gives consumers flexibility that which attributes they want in response. REST API has problem of under and over fetching of data because of fixed structure of response and GraphQL eliminates this by providing only those attributes which are asked in the request.
In this course you will learn GraphQL in detail with Spring Boot and Spring Data JPA using MySQL database. In this course you will learn :-
What is GraphQL ?
Difference between GraphQL and REST API
What is Query in GraphQL ?
What is Mutation in GraphQL ?
What is Schema in GraphQL ?
What is Resolver in GraphQL ?
What is Edge in GraphQL ?
In this course you will learn to create GraphQL Query and Mutation with Spring Boot. You will learn to create Resolver with Edge in Spring Boot.
Project lombok is used to avoid boiler plate code in your Java Application. In this course you learn how to use Project Lombok with Spring Boot Application and you will learn -
How to have getter methods for Java Class using @Getter Annotation.
How to have setter methods for Java Class using @Setter Annotation.
How to have constructor for Java Class using @NoArgsConstructor and @AllArgsConstructor Annotations.
After finishing the course you will be able write GraphQL queries as shown in Promo video and also you will be able to deploy your GraphQL-Spring Boot Application to Heroku which is Cloud Platform.
Lets start journey of GraphQL with Spring Boot and Spring Data JPA.
