Entity maps
Entity maps help teams understand the relationships between business concepts.
When entities are assigned to a domain or service, EventCatalog can create an entity map that shows:
- The entities assigned to that resource.
- Relationships between those entities.
- Entities referenced from outside the current resource.
- Which entities are owned by the current domain or service context.
Open an entity map in the visualizer
Domains and services have dedicated entity map routes:
/visualiser/domains/{id}/{version}/entity-map
/visualiser/services/{id}/{version}/entity-map
When a domain or service has entities assigned, an Entity Map link appears automatically in the resource sidebar under the visualizer section.
Embed an entity map
You can also embed an entity map on a page using the <EntityMap /> component.
<EntityMap id="ordering" title="Ordering Entity Map" />
Use embedded entity maps when you want the model to appear directly in domain, service, or custom documentation.
