Exposes the endpoint POST /graphql for query requests

query {
  usersById(id: "1") {
    name
    email
  }
}

type UserDto {
  id: ID
  name: String
  email: String
}

Converts open api to graphql schema

Springboot server that exposes the following endpoints:

• POST /graphql for query and mutation requests
• GET /registry to list registered services in the gateway
• DELETE /registry to unregister services from the gateway
• POST /registry to register services in the gateway

Exposes the following endpoints to manage registration of services:

POST /registry to register services in the gateway

curl --location --request POST 'http://localhost:8080/registry' \
--header 'Content-Type: application/json' \
--data-raw '{
"name": "UsersService",
"url": "http://localhost:8082/v3/api-docs"
}'

DELETE /registry to unregister services from the gateway

curl --location --request DELETE 'http://localhost:8080/registry?service=UsersService' \
--header 'Content-Type: application/json' \
--data-raw '{
"name": "UsersService",
"url": "http://localhost:8082/v3/api-docs"
}'

This Outlines the recommended development guidelines for services to be registered with the GraphQL gateway.

• Use open api to describe your service

<dependency>
  <groupId>org.springdoc</groupId>
  <artifactId>springdoc-openapi-ui</artifactId>
  <version>1.6.9</version>
</dependency>

• Naming conventions:
  • Service names should be in PascalCase.
  • Endpoint names should be in camelCase.
  • Operation names should be in camelCase and descriptive.
  • Field names should be in camelCase.
