This guide will demonstrate a single instance installation of ArangoDB but you can also do: The process of installing ArangoDB on Ubuntu 20.04/18.04 is straightforward.

Has a flexible data modeling which allows you to model your data as combination of key-value pairs, documents or graphs – perfect for social relations.It is fully open source and released under Apache 2.0 License.Just to compare, here’s the DepartmentInput class. = true)Īlso, let’s take a look at the Department entity. Here’s the Employee entity corresponding to the Employee object defined in GraphQL schema. However, I prefer to use Lombok annotations, so I will do it manually.

We could have generated Java source code using previously defined GraphQL schemas. We also have an input object for mutation and a standard type definition for queries. There is the QueryResolver with two find methods and the MutationResolver with a single method for adding new departments. GraphQL schema for each entity is located in the separated file. Thanks to that, the Netflix DGS library detects and loads them automatically. A schema may be defined in multiple graphqls files, but all of them have to be placed inside the /src/main/resources/schemas directory. īefore we start implementation, we need to create GraphQL schemas with objects, queries, and mutations. Here’s a list of required dependencies in Maven pom.xml. Of course, we also have to include Netflix DGS Spring Boot Starter. We need to include Spring Web, Spring Data JPA, and the com.database:h2 artifact for running an in-memory database with our application. Dependencies for Spring Boot and Netflix GraphQL A relationship model between them is visualized in the picture below. I have implemented three entities Employee, Department and Organization – each of them stored in the separated table. For integration with the H2 database, I’m using Spring Data JPA and Hibernate. We will discuss Spring Boot GraphQL JPA support. I created an application that exposes API using GraphQL and connects to H2 in-memory database. The example with GraphQL Java Kickstart is available inside the sample-app-kickstart directory.Īs I mentioned before, we use the same schema and entity model as before. Then you should just follow my instructions.įirst, you should go to the sample-app-netflix-dgs directory. In order to do that you need to clone my GitHub repository. If you would like to try it by yourself, you may always take a look at my source code. Let me just briefly describe our scenario.

In order to show you the differences between this library and the previously described Kickstart library, I’ll use the same Spring Boot application as before. It simplifies writing unit tests and also supports websockets, file uploads, or GraphQL federation. Netflix DGS allows generating source code from GraphQL schemas.

Besides the annotation-based programming model, it provides several useful features.

Consequently, it is dedicated to Spring Boot applications. Netflix DGS is an annotation-based GraphQL Java library built on top of Spring Boot. Since Netflix DGS has been released some months ago, you might want to take look at it. However, it is based on a different library called GraphQL Java Kickstart ( ). I published a similar article some months ago: An Advanced Guide to GraphQL with Spring Boot. We will discuss more advanced topics related to GraphQL and databases, like filtering or relationship fetching.

In this article, you will learn how to use the Netflix DGS library to simplify GraphQL development with Spring Boot.
