Course Description

Are you someone who want to learn GraphQL with spring boot java and how to test GraphQl application then you are in right place :).

You will learn what is GraphQl and how to set up the graphQL project with spring boot.


What is GraphQL?

A query language for your API

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.


Ask for what you need,

get exactly that

Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server.

Awesome lectures so far. He is able to explain things clearly even though english does not seem to be his first language. Thank you very much.

By Stuart Thomas on 11/21/2022

The version of Spring boot starter is old. V 2.6.x and higher doesn't work

By John Richardson on 6/29/2022

Just getting started here with you course and I will come back to add more comments. Out of the gate I believe that you should update your course and project code to use the new 'com.graphql-java-kickstart' libraries since the 'com.graphql-java' libraries are no longer being supported and the new project is a direct fork from the old and built upon. Thanks for the course and I let you no more as I go on! vr/ John Richardson

The course was very elaborative and easy to understand. Faced some issue with the new dependencies. But the topics of GraphQL can be decoupled from the other topic and can be made as optional part. Thanks for the knowledge!

By John Adeshola on 6/5/2022

Well detailed course. Every bit of the course was very interesting and details. Easy to follow through.

By Dorothy Rifai on 9/4/2021

It is a good match for me, but it would be more helpful if the instructor provided the code in a GitHub repo, particularly for the early lectures when the student doesn't have context for troubleshooting. I had to listen to 1 lecture about 3 times before I picked up what I was doing wrong. The code is posted for the final version,, but not for the early versions before the database is wired up.

By Kanishk Bhatt on 7/25/2021

The instructor have worked well on arranging the sequence of topic in a planned manner. However it is missing one key feature which is Apollo client using which we can write java/spring code to call any graphql based service. Also instructor need to work on the presentation.

By Kiran Kumar K on 6/27/2021

Vikas, if possible can you share us code either with github repository and in resources folder attached to section. This could be helpful to me!

By Prerna Shah on 6/11/2021
