Commanded is an Elixir framework for implementing CQRS (Command Query Responsibility Segregation) and Event Sourcing patterns. It provides domain-driven design tools—aggregates, commands, events, and projections—backed by an event store (e.g. PostgreSQL).
Features
- Structure for commands, aggregates, and event handling
- Support for multiple event stores (Postgres, EventStoreDB, etc.)
- Automatic snapshotting and rehydration of aggregate state
- Projector support via Ecto for read models
- Middleware and router pipelines for event/command processing
- Community extensions (audit middleware, telemetry, adapters)
