spring-boot-graphql-template

Spring Boot, GraphQL template project with batteries included.

Features

​

• Docker 🐳 configuration for production deployment, development and test
  • Remote debugging for development mode

Required Software

• JDK 1.8
• Or docker + docker-compose

Lombok

IntelliJ

• Download and install Lombok plugin
• Enable Annotation Processors
  • Go to Setting->Build, Execution, Deployment-> Compiler->Annotation Processors
  • Check Enable annotation processing

GraphQL Tools

IntelliJ

• Download and install GraphQLJs plugin

Style check

IntelliJ

• You can download "CheckStyle plugin". Then open Settings > Other Settings > Checkstyle. Add path to check-style.xml file and provide link to check-style folder in "${configDir}". This will display errors in editor and it wont affect build/run.

Gradle

• As default behaviour it is configured to call "checkstyleMain pmdMain" before "build" task is executed, which does not prevent development (application start up and bootrun)

Develop

1.1. Run

• Gradle: $ gradlew bootRun
• Docker: $ docker-compose up (or $ docker-compose up --build if image should be rebuilt)

1.2. Debug

Run remote debugger from IDE. Debug port is 5005

Test

• Gradle: $ gradlew test
• Docker: $ docker-compose -f docker-compose.test.yml up --build

Build

• Gradle: $ gradlew buld
• Docker: $ docker build -t spring-boot-graphql-template .

Run productive

Assuming that the Docker image is already built on the previous step

• Docker (add -d to run in daemon mode): $ docker run -p 8080:8080 spring-boot-graphql-template

Tech Stack

• Spring Boot : Application framework
• Feign : HTTP Client library
  • Feign-Hystrix : wraps Feign's http requests in Hystrix, which enables the Circuit Breaker pattern.
• Lombok : Utility library for Java language
• GraphQL : API query runtime
  • GraphQL and GraphiQL Spring Framework Boot Starters
  • GraphQL Java Tools
• GraphQL Voyager : Represent any GraphQL API as an interactive graph. See Voyager Sample
• GraphQL Playground : GraphQL IDE for better development workflows (GraphQL Subscriptions, interactive docs & collaboration). See Playground Sample
• Docker

Packaging

• Use the Models and Connectors pattern to structure our GraphQL server code, since it is a well established pattern in GraphQL world. Such approach allows to refer to the existing approach instead of coming up with our own set of guidelines.
