📦 plugin-generator-asyncapi

EventCatalog plugin to generate a catalog from your AsyncAPI files.

This plugin will generate Service and Event documents based on your AsyncAPI file.


Once setup run npm run generate within your project.

How it works

The plugin will parse your AsyncAPI file looking for events and services and use this information for your catalog.

What if I already have events and services?

The plugin will check to see if the service or event already exists. If true then the events will be versioned (based on your config) and services will be overriden (until service version is working).

If you already have configured markdown in your events or services, this markdown will be reused in your new generation. This means the content (documentation) of your events and services will be kept the same, but the metadata (frontmatter) will be updated (version, naming, summarys, links etc).

How is this plugin useful?

You may be a team that likes to be spec driven, so you can keep your spec up to date and continue to work on it and just run npm run generate in the catalog to have the features from EventCatalog.

You can use EventCatalog with AsyncAPI specs to enhance your documentation and use all the features of EventCatalog (3D node graphs, Diagrams, Documentation and much more...).


npm install --save @eventcatalog/plugin-doc-generator-asyncapi


pathToSpecstring or string[]'/asyncapi.yml'Path or Paths to AsyncAPI documents.
versionEventsbooleantrueWhen the plugin runs and it finds matching events in the catalog, it will version the events before creating the new documentation.
externalAsyncAPIUrlstring``When a AsyncAPI base url is set the, a external link to the AsyncAPI message documentation will be added to each event.

renderNodeGraphbooleanfalseWhen set to true is will render the NodeGraph diagram to the matched events from the AsyncAPI file.

Example Configuration

Plugin Options

You will need to add the plugin into the generators part of the eventcatalog.config.js file.


const path = require('path');

module.exports = {
generators: [
// path to your AsyncAPI files
pathToSpec: [path.join(__dirname, 'asyncapi.yml')],

// version events if already in catalog (optional)
versionEvents: true

This will read the asyncapi.yml file in the root of your project. You can provide whatever path you wish.
