About

This project is inspired by Springfox. It documents asynchronous APIs using the AsyncAPI specification.

springwolf-ui adds a web UI, much like that of Springfox, and allows easy publishing of auto-generated payload examples.

🪇 Demo & 📖 Documentation

Take a look at the Springwolf live demo and a generated AsyncAPI document.

springwolf.dev includes the quickstart guide and full documentation.

✨ Why You Should Use Springwolf

Springwolf exploits the fact that you already fully described your consumer endpoint (with listener annotations, such as @KafkaListener, @RabbitListener, @SqsListener, etc.) and generates the documentation based on this information.

Share API Schema Definition

The AsyncAPI conform documentation can be integrated into API hubs (like backstage) or be shared as a json/yaml file with others.

UI Based API Testing

In projects using asynchronous APIs, you may often find yourself needing to manually send a message to some topic, whether you are manually testing a new feature, debugging or trying to understand some flow.

Using the automatically generated example payload object as a suggestion, you can publish it to the correct channel with a single click.

🔬 Usage & Example

Protocols not supported natively can still be documented using @AsyncListener and @AsyncPublisher annotation. More details in the documentation.

Testing SNAPSHOT version

Sonatype snapshots

Add the following to the repositories closure in build.gradle:

repositories {
    // ...
    maven {
        url "https://s01.oss.sonatype.org/content/repositories/snapshots" // build.gradle
        // url = uri("https://s01.oss.sonatype.org/content/repositories/snapshots") // build.gradle.kts
    }
}

Or add the repository to your pom.xml if you are using maven:

<repositories>
    <repository>
        <id>oss-sonatype</id>
        <name>oss-sonatype</name>
        <url>https://s01.oss.sonatype.org/content/repositories/snapshots</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

Local Snapshot Build

To test with local builds, run the publishToMavenLocal gradle task. The current version number is set in .env file.

Do not forget to add mavenLocal() to the repositories section.
