Event sourcing works nicely with aggregates from Domain driven design.
An aggregate has the responsibility of creating immutable events, command handlers that emit these events and validate them too.
Besides creating these events, they can be instantiated and create a state from consuming this history of events, or in other words “applying these events” with event handlers.
