toml [dependencies] cqrs-es = "0.0.15"

Opinions

• Aggregate persistence is via event sourcing only.
• Support for JSON serialization only.
• Generics are preferred over boxed traits.
• Persistence is implemented through a Postgres database.

Todos/research

• Event upcasters.
• Event serialization uses the event type as the root node of the JSON tree. This simplifies deserialization but is non-standard.
• A persistence implementation for DynamoDb.
• Support for snapshots.
