GraphQuery

A GraphQL query generator for Java projects.

Building

Simply run gradlew build to compile the project once it has been cloned.

Artifacts

GraphQuery is accessible to your project via a Maven repository. Just add the following to your project:

Gradle:

repositories {
    maven { url "https://waifu.me/maven" }
}

dependencies {
    compile "me.waifu.graphquery:GraphQuery:${version}"
}

Replace ${version} with the version you want.

Example

Java code

public class QueryTest {
    public static void main(String... args) throws Exception {
        GraphQLQuery query = new GraphQLQuery(GraphQLQuery.RequestType.QUERY, $ -> {
            try {
                $.withUrl("https://fakerql.com/graphql");
            } catch (Exception e) {
                e.printStackTrace();
            }
            $.withArgument("someBool", "Boolean!");
            $.withVariable("someBool", true);
            $.withObject(root -> {
                root.withObject("allUsers", allUsers -> {
                    allUsers.withArgument("count", 1);
                    allUsers.withField("id");
                    allUsers.withField("firstName").withAlias("first");
                    allUsers.withField("lastName").withAlias("last");
                    allUsers.withField("avatar").includeIf("someBool");
                    allUsers.withField("email").skipIf("someBool");
                }).withAlias("users");
            });
        });
        FutureTask<String> task = query.createRequest();
        task.run();
        System.out.println(task.get());
    }
}
