Events are a type of message that represent immutable facts.

In EventCatalog Services may send (produce) or receive (consume) events in your architecture.

Example of an event

An example of an event would be OrderPlaced event.

• This event is a fact that an order has been placed.
• Other services (consumers) may be interested in this event and can typically subscribe to it.

Events in EventCatalog

• Events in EventCatalog are orange (following EventStorming conventions)
• Events live in the /events folder or inside a service folder.
