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.

I learned some good stuff about GraphGL in a shortish time. The presentation was too repetitive, repeating the same thing many times. Some of the chapters were not very relevant, such as Heroku, and Lombok. I use Lombok all the time, but I dont require a whole section to explain it. I didnt like that the course was first using an older version of GraphGL and then updated to a newer version in later section 13. Also, the course should be updated to SpringBoot 3

!!! OUTDATED-OUTDATED-OUTDATED !!! Don't waste your time and money on this course. The author does not even try to answer questions anymore or update the videos.

The course is good. Need to update this course with Spring Boot - 3. In the v3, the kick-start dependency is removed and new graphql-starter dependency is created.

Nice lecture, but few things are left like scalar, how to create new scalar and configure in the code that is not added. apart from that everything is good.

it looks like this course is not the latest version of Spring Boot https://spring.io/projects/spring-graphql While content is good but it is different from the project I am working on now

outdated course need to update. same things repeat multiple time, if someone need to listen same things multiple times then person can replay video.

This course is using some commands and functions that are not working .i feel it is outdated as in the course it is asked to use @Component etc but only @Controller works and I had to reasearch in google to add few extra dependencies etc to make it work(@QueryMapping ,POM.xml etc) The author is not responding to any queries asked in the QA section

The course is brilliant, but it is outdated. Also, the Heroku deployment section is useless; I did not find its use.

Cloud deployment section is irrelevant. Role based access, pagination or streaming response could have been included

You got the essential knowledge to start working with Graphql with spring boot. I've missed some more complex examples like authentication, and multiple filters using complex objects queries. Even though, this course worth a lot. I recomend it

downloaded material is not exactly running. Till now I find big gap in video and downloaded example. Need improvement and look at the comments by different trainee for asking different questions related lecture.
