Integrate AsyncAPI with EventCatalog

· 2 min read

EventCatalog now supports integration and document generation from your AsyncAPI specification files.

The new asyncapi-plugin has now been released which allows you to generate documents from your events and services automatically.

How plugins work with EventCatalog

EventCatalog is built to support many brokers, languages and specifications. This allows us to remain technology agnostic and integrate with users existing solutions.

EventCatalog supports generation plugins which you can use to generate documentation from any third party source.


Want to integrate with something else? You can write your own plugin! You can use the @eventcatalog/utils to help you too!

Let's take a quick look at how the generation works...


As we see in the diagram above, EventCatalog supports a generation phase. This means when you run npm run generate on your catalog it will go through all your configured plugins and execute them.

How does generation work with AsyncAPI?

When you configure and install the asyncapi-plugin and run npm run generate your AsyncAPI file is parsed and services, events and schemas are extracted from it.


This information is then stored inside the correct places within your catalog and you should be good to go!


If your AsyncAPI version has changed since last time, EventCatalog will version your previous events and use the new ones at the latest version.

What happens to content already in the Catalog?

If you already have events and services documented in your catalog, the asyncapi-plugin can version your events for you (configurable) before overriding them.

Any content you add in your existing events or services will be used and not overridden on the next generation phase. This means you can keep all your custom markdown content without replacing it every time you generate your documents. The frontmatter of your services and events will be the only things that are replaced.


AsyncAPI is a great way for people to document their architectures, allowing you to describe servers, services, events, schemas and much more.

EventCatalog now supports integration with AsyncAPI which hopefully helps you get all the benefits of the catalog alongside your AsyncAPI files.

To get started head over to the async-api plugin api documentation.
