Vert.x Web GraphQL examples

Here you will find examples demonstrating Vert.x Web GraphQL in action.

Vert.x Web GraphQL extends Vert.x Web with the GraphQL-Java library so that you can build a GraphQL server.

This example uses the Vert.x Web client to send a request to the GraphQL server and log the response.

The backend is a very basic Hackernews clone: it holds a list of web pages, as well as info about the user who posted each link. The GraphQL schema describes the data with:

• Link and User types

• the allLinks query

First you need to run the server then you can run the client.

• Simple Java GraphQL server

• Simple Java GraphQL client

The client of this example starts an Apollo subscription on the server and log each message received. The connection is done through a Websocket.

The server responses with the link list of the simple exmple, but with each item in a separated websocket message.

First you need to run the server then you can run the client.
