Commanded

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)
