Configuration​

Configure the plugin in your eventcatalog.config.js file.

Add the plugin to the generators array.

eventcatalog.config.js
// ...
generators: [
  // Add single AsyncAPI file to a domain
  [
    '@eventcatalog/generator-asyncapi',
    {
      services: [
        { path: path.join(__dirname, 'asyncapi-files', 'orders-service.yml'), id: "Orders Service"}
      ],
      domain: { id: 'orders', name: 'Orders', version: '0.0.1' },

      // Run in debug mode, for extra output, if your AsyncAPI fails to parse, it will tell you why
      debug: true
    },
  ],
  // Add many AsyncAPI files to a domain
  [
    '@eventcatalog/generator-asyncapi',
    {
      services: [
        // Add AsyncAPI file by URL
        { path: "https://raw.githubusercontent.com/event-catalog/eventcatalog-asyncapi-example/refs/heads/main/asyncapi-files/payment-service.yml", id: "Payment Service"}
        // Add AsyncAPI file using file system
        { path: path.join(__dirname, 'asyncapi-files', 'fraud-detection-service.yml'), "Fraud Service"}
      ],
      domain: { id: 'payment', name: 'Payment', version: '0.0.1' },
      // Run in debug mode, for extra output, if your AsyncAPI fails to parse, it will tell you why
      debug: true
    },
  ],
],
};

Configure license key​

The EventCatalog AsyncAPI plugin requires a license key to work with EventCatalog.

You can get a trial license key from EventCatalog Cloud.

Setting license key in environment variables​

Setting license key in environment variables
export EVENTCATALOG_LICENSE_KEY_ASYNCAPI=your-license-key

Setting license key in eventcatalog.config.js​

If you prefer, you can set the license key in the eventcatalog.config.js file using the licenseKey property in the EventCatalog AsyncAPI plugin.

eventcatalog.config.js
export default {
  generators: [
    [
      '@eventcatalog/generator-asyncapi',
      {
        licenseKey: '[INSERT_YOUR_LICENSE_KEY]', // or process.env.EVENTCATALOG_LICENSE_KEY_ASYNCAPI
      },
    ],
  ],
};

White listing domains​

If you are behind a firewall you will need to white list the domain https://api.eventcatalog.cloud in your firewall. This is because the plugin needs to verify your license key.

Run the plugin​

This command will run the generators in your eventcatalog.config.js file.

npm run generate

View your catalog​

Run your catalog locally to see the changes
