How it works

EventCatalog is technology agnostic, meaning it can integrate with any schemas, specs or brokers.

EventCatalog supports generators. Generators are scripts are run to pre build to generate content in your catalog. Generators can use the EventCatalog SDK.

With this OpenAPI plugin you can connect your OpenAPI files to your catalog. This is done by defining your generators in your eventcatlaog.config.js file.

...
generators: [
    [
      '@eventcatalogtest/generator-openapi',
      {
        services: [
          { path: [path.join(__dirname, 'openapi-files', 'petstore.yml'), id: 'pet-store' },
          { path: [path.join(__dirname, 'openapi-files', 'account-service.yml'), id: 'account-service' },
        ],
        domain: { id: 'orders', name: 'Orders', version: '0.0.1' },
      },
    ],
  ],
...

In this example the generator will read the petstore.yml file and populate services and messages inside your catalog. It will add the service to the domain Orders.
