Awesome graphql-java

Libraries and projectes related to graphql-java

Inspired by the awesome list thing.

Examples

• todomvc-relay-java: Port of the Relay TodoMVC example to a java backend
• graphql-datetime-sample-app: GraphQL example app with usage of date and time scalars
• spring-petclinic-graphql: Port of the Spring PetClinic to Spring Boot, graphql-java and graphql-spring-boot-starter (using React Apollo in the frontend)

Schema Libraries

Schema First

• GraphQL Java Generator is available as a Maven plugin and a Gradle plugin. It has two modes :

  • The Client mode generates the Java classes that contains methods to call the GraphQL endpoint , and the POJO that will contain the data returned by the server.

  • The Server mode generates the boilerplate code for graphql-java. It's an accelerator that makes it easier to use graphql-java. You'll only have to implement what's specific to your server, which are the joins between the GraphQL types.

• graphql-apigen: Generate Java APIs with GraphQL Schemas

• graphql-java-tools: A schema-first tool for graphql-java inspired by graphql-tools for JS

• graphql-java-codegen-maven-plugin: Maven plugin for generating Java types and Resolver interfaces. Works perfectly in conjunction with graphql-java-tools.

• graphql-java-codegen-gradle-plugin: Gradle plugin for generating Java types and Resolver interfaces. Works perfectly in conjunction with graphql-java-tools.

• rdbms-to-graphql: A Java CLI program that generates a GraphQL schema from a JDBC data source.

• graphql-schema-from-introspection-generator: A Java CLI program that generates a GraphQL schema from Introspection Query result. Useful for migration from Code First.

• graphql-braid: Schema stitching - combines GraphQL backends into one schema.

• test-graphql-java: A simple library to help testing the GraphQL endpoint with schema files using any HTTP Client library.

• graphql-java-federation: A library to adapt graphql-java services to Apollo Federation specification

Exposing a Schema

• graphql-java-servlet: Servlet that automatically exposes a schema dynamically built from GraphQL queries and mutations.

• graphql-spring-boot: GraphQL and GraphiQL Spring Framework Boot Starters

• graphql-jpa-spring-boot-starter: Spring Boot starter for GraphQL JPA; Expose JPA entities with GraphQL.

• Light Java GraphQL: A lightweight, fast microservices framework with all other cross-cutting concerns addressed that is ready to plug in GraphQL schema.

• Moqui GraphQL: An addon of Moqui framework to generate GraphQL Schema automatically.

• GORM GraphQL: An fully customizable addon for GORM (Grails Object Relational Model) to generate a GraphQL schema automatically.

• Vert.x GraphQL Utils - Vert.x route handler and Vert.x compatible interfaces to handle GraphQL queries in Vert.x applications.

• dropwizard-graphql - Dropwizard bundle for exposing a GraphQL endpoint (uses graphql-java-servlet internally)

• graffiti - a headless Java CMS.

• spring-boot-starter-graphql - Spring Boot Starter for GraphQL.

• micronaut-graphql: Provides Micronaut GraphQL integration.

• vertx-web-graphql: Extends Vert.x Web with the GraphQL-Java library so that you can build a GraphQL server.

Validation

• graphql-java-extended-validation: A validation library that allows use of @directives to indicate how to validate graphql input arguments.

Batch Loading
