Project initialization

Edit the build.gradle and add:

implementation 'com.google.cloud:spring-cloud-gcp-starter-data-firestore'

Run project

.\gradlew.bat bootrun

Graphql

Add depdencies in build.gradle

implementation 'org.springframework.boot:spring-boot-starter-graphql'

enable UI for graph ql application.properties

spring.graphql.graphiql.enabled=true

Basics

Add home controller

package top.productivitytools.waypoint.api.controllers;

import org.springframework.graphql.data.method.annotation.Argument;
import org.springframework.graphql.data.method.annotation.MutationMapping;
import org.springframework.graphql.data.method.annotation.QueryMapping;
import org.springframework.stereotype.Controller;

import lombok.RequiredArgsConstructor;

@Controller
@RequiredArgsConstructor
public class HomeController {
    @QueryMapping
    public String helloQuery() {
        return "Hello World";
    }

    @MutationMapping
    public String Hello(@Argument("name") String name) {
        var response = "Hello " + name;
        return response;
    }
}

Add graphql

type Mutation{
    Hello(name: String!):String
}

type Query {
    helloQuery: String
}

Testing

http://localhost:8080/graphiql

query {
  helloQuery
}

mutation {
  Hello(name: "Pawel")
}
