GraphQL query builder for Java

Installation

Maven (pom.xml)

<dependencies>
    <dependency>
        <groupId>com.github.k0kubun</groupId>
        <artifactId>graphql-query-builder</artifactId>
        <version>0.4.2</version>
    </dependency>
</dependencies>

Gradle (build.gradle)

dependencies {
    compile 'com.github.k0kubun:graphql-query-builder:0.4.2'
}

Usage

To build following query:

user(name:"k0kubun") {
  name
  friends(first:10 after:"Y3Vyc29yMQ==") {
    totalCount
    edges {
      cursor
      node {
        ... on User {
          name
        }
      }
    }
  }
}

You can write code in the following way:

import com.github.k0kubun.builder.query.graphql.GraphQLQueryBuilder;
import java.util.HashMap;
import java.util.Map;

public class Example {
    
    public example() {
    Map<String, Object> userParams =
                    Map.of("name", "k0kubun");
    
            String query = GraphQLQueryBuilder.query()
                    .object("user", userParams, GraphQLQueryBuilder.object()
                            .field("name")
                            .objects("friends", 10, "Y3Vyc29yMQ==", GraphQLQueryBuilder.object()
                                    .field("totalCount")
                                    .object("edges", GraphQLQueryBuilder.object()
                                            .field("cursor")
                                            .object("node", GraphQLQueryBuilder.object()
                                                    .on("User", GraphQLQueryBuilder.object()
                                                            .field("name")
                                                            .build()
                                                    ).build()
                                            ).build()
                                    ).build()
                            ).build()
                    ).build();
    }
}

Code style

Airlift

Release

Create ~/.gradle/gradle.properties like:

sonatypeUsername=k0kubun
sonatypePassword=PASSWORD
signing.keyId=KEYID
signing.password=PASSWORD
signing.secretKeyRingFile=/Users/k0kubun/.gnupg/secring.gpg

KEYID is the last 8 characters of what's shown at gpg -K.

Then run:

$ ./gradlew uploadArchives

At https://oss.sonatype.org/#stagingRepositories, push "Close" and then "Release". Sync to maven repository might take some time.
