The Apicurio Registry plugin is used to generate a catalog from an Apicurio Registry and import your schemas and specifications into EventCatalog.

You can map your schemas from your Apicurio Registry to events, commands, or queries in your catalog, and assign these to services and domains.

Installation

Run the command below to install the EventCatalog Apicurio Registry plugin.

"Don't have an EventCatalog project yet?"

If you don't have an EventCatalog project yet, you can follow the instructions in the Getting Started guide.

npm i @eventcatalog/generator-apicurio

Configuration

To use the plugin you need to configure it in your eventcatalog.config.js file.

Add the plugin to the generators array.

Import all schemas

In this example we import all schemas from an Apicurio Registry into EventCatalog.

You can also create services and assign schemas to them, along with domains. (see examples).

eventcatalog.config.js

// ...
generators: [
  // 1. Import all schemas from an Apicurio Registry
  [
    '@eventcatalog/generator-apicurio',
    {
      // The URL of your Apicurio Registry
      registryUrl: 'http://localhost:8080',
      // Do you want to include all versions of a schema? (default: false)
      includeAllVersions: true
    },
  ],
];

Import schemas and assign them to services and domains

In this example we document services, assign schemas to them, and organize everything within a domain.

We create an orders domain and an Orders Service that sends and receives messages.

eventcatalog.config.js

// ...
 [
  '@eventcatalog/generator-apicurio',
      {
        // The URL of your Apicurio Registry
        registryUrl: 'http://localhost:8080',
        // The services to assign schemas to (optional)
        services: [
          {
            id: 'Orders Service',
            version: '1.0.0',
            // the messages this service sends
            // We use the prefix matching against the artifact name
            sends: [
              { events: { prefix: 'order-' } }
            ],
            // the messages this service receives
            // We use the exact matching against the artifact name
            receives: [
              { commands: ['place-order', 'cancel-order'] }
            ],
          },
        ],
        domain: {
          id: 'orders',
          name: 'Orders',
          version: '1.0.0',
        }
      },
    ],

Configure API keys

The EventCatalog Apicurio Registry plugin is open source under the MIT License and doesn't need a license key. If your config still sets licenseKey or an EVENTCATALOG_LICENSE_KEY_* variable, you can remove it; it's ignored.

If your Apicurio Registry requires authentication, create a .env file in the root and add your access token to the project.

.env

# Apicurio Registry Bearer Token (optional - only if your registry requires authentication)
APICURIO_ACCESS_TOKEN=your-access-token-here
