GraphQL

Micro frontends using WebComponents and MicroProfile GraphQL

Microservices architectures are great when you have small, autonomous teams that take care of a certain use case in your overall solution. However, this usually all needs to come together in a UI.

In this talk we will explore the feasibility of using GraphQL and WebComponents to build Micro Frontends, extending the autonomy to the UI, allowing teams to scale even better.

We will look at a small example using Quarkus, MicroProfile GraphQL and WebComponents.

Writing queryable APIs with MicroProfile GraphQL

Phillip Kruger (Red Hat, Inc.)

“GraphQL is a data query language developed internally by Facebook in 2012 before being publicly released in 2015. It provides an alternative to REST and ad-hoc web service architectures.”

In this talk, we will

Go through the basics of GraphQL
Discuss the differences with REST
Discuss the features in the current and future MicroProfile GraphQL API
Go through a basic example in Java using Quarkus.

We will look at the following GraphQL concepts:

MicroProfile GraphQL and JPA: Meant for each other

Andy McCright (IBM)

Can it really be that easy?! Yes it can! Come check out this session where we'll discuss and demo how you can rapidly build data-driven microservices using GraphQL. MicroProfile GraphQL makes it simple to create Java-based GraphQL services with a few annotations. JPA makes it simple to access data in a database. When you put these two technologies together, sparks will fly (the good kind)! With very little code, we can build services that allow clients to get exactly what they want from the database.

API Design made easy with the GraphQL Whiteboard

Jürgen Albert (Data In Motion Consulting GmbH)

Graphql is a great alternative to REST and takes a lot of headache out of the Design of a good API. Created by Facebook and made Opensources a few years back, it has an increasing populairty. See how to use the Gecko GraphQL Whiteboard easiely expose your Services via GraphQL or write a specific custom API .

When GraphQL meets MicroProfile

Jean-François James (Worldline)

Jean-Baptiste Roux (Worldline)

The aim of this talk is to answer the following questions:

What is GraphQL?
How does it compare to REST: competitor or complement?
How does it fit with Java in general and MicroProfile in particular?
What is MicroProfile GraphQL?
Why should you care?

Going from an introduction to GraphQL, a presentation of MicroProfile, a live demo, we want the audience to get a better graps of what MicroProfile GraphQL can provide to develop modern APIs.

A GraphQL API for EMF

Stephane Begaudeau (OBEO)

While moving Eclipse Sirius to the web, we have created an HTTP API to interact with the Sirius server. In this talk, you will have a look at the GraphQL API for EMF that we have integrated in Eclipse Sirius. With this API, you will have the ability to easily manipulate your models over HTTP. This API can even be parameterized using any metamodel to let users have a GraphQL API with their own concepts and relationships.
