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 EventBridge plugin you can connect your schema registries to your catalog. You can map your events to your domains and services and also filter (suffix, prefix, exact matching, source filtering) for your events.

This is done by defining your generators in your eventcatlaog.config.js file.

``js
...
generators: [
[
'@eventcatalog/generator-eventbridge',
{
region: 'us-east-1',
registryName: 'discovered-schemas',
services: [
// Maps exact events to the service
{ id: 'Orders Service', version: '1.0.0', sends: [{ detailType: ['OrderPlaced', 'OrderUpdated'], receives:["InventoryAdjusted"]}] },
// Filter by source (all events that match the source get assigned). This example shows any event matching the source
// "myapp.orders" will be assigned to the inventory service. The inventory service will publish these events.
{ id: 'Inventory Service', version: '1.0.0', sends: [{ source: "myapp.orders"}], receives:[{ detailType: "UserCheckedOut"}] },
// This service sends events that match the SchemaName prefixing myapp, and will receive events that end with Payment
{ id: 'Payment Service', version: '1.0.0', sends: [{ prefix: "myapp"}], receives:[{ suffix: "Payment" }] }
],
domain: { id: 'orders', name: 'Orders', version: '0.0.1' },
},
],
// Example of saving all messages directly into EventCatalog without services or domains
// All events in registry will be added to the Catalog.
[
'@eventcatalog/generator-eventbridge',
{
region: 'us-east-1',
registryName: 'discovered-schemas'
},
],
// Example using optional credentials
[
'@eventcatalog/generator-eventbridge',
{
region: 'us-east-1',
registryName: 'discovered-schemas',
credentials: {
accessKeyId: 'X',
secretAccessKey: 'X',
accountId: 'X',
},
},
],
],
...
`

In this example we have two types of usecases for the generator:

1. Map events to services and domains using custom filters.
2. Add all events to EventCatalog regardless of the service or domain.

You can see an example in the eventcatalog-eventbridge-example repo
