Micronaut Framework codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API

This codebase was created to demonstrate a fully fledged fullstack application built with Micronaut including CRUD operations, authentication, routing, pagination, and more.

We've gone to great lengths to adhere to the Micronaut community styleguides & best practices.

For more information on how this works with other frontends/backends, head over to the RealWorld repo.

Live Demo

Check out the live application on Render:

Resource	URL
api	https://realworld-backend-micronaut.onrender.com/api
swagger-ui	https://realworld-backend-micronaut.onrender.com/swagger-ui

💡 The application is deployed on a free tier, so it may take a few seconds to start.

How it works

App

• Micronaut Framework
• Micronaut Data JPA with Hibernate
• Micronaut Liquibase for the database changes management
• Micronaut Declarative HTTP Clients for integration tests
• Micronaut Security JWT for authentication and authorization
• Micronaut Management built-in endpoints
• Micronaut OpenAPI/Swagger
• H2 in memory database
• GraalVM support

CI

• Github Actions
• Building jar
• Building GraalVM native image for Linux, macOS, and Windows
• Building Docker image with the native executable and pushing it to GitHub Container Registry
• Execution of Realworld Postman collection with newman for all the builds
• Code coverage with Codecov
• Publishing GitHub release with the artifacts
• Triggering deployment on Render

Getting started

Note that Java 17 or above is required to build the project with Gradle.

JVM

Run the application with Gradle:

./gradlew run

Or download the latest artifact from the releases page, and run:

java -jar realworld-backend-micronaut-*.jar

Native Image

Run the application with Gradle:

./gradlew nativeRun

Or download the latest artifact for your platform from the releases page, unpack, and run the executable:

./realworld-backend-micronaut

Docker

Run the application with Docker:

docker run -p 8080:8080 ghcr.io/alexey-lapin/realworld-backend-micronaut:latest

Try it out with a RealWorld frontend

The entry point address of the backend API is at http://localhost:8080/api

Run test

The repository contains a lot of test cases to cover both api test and repository test.

./gradlew test
