fluxEvent-Sourcing Framework for Go

Build distributed, event-sourced applications with type-safe aggregates, commands, and projections.

Event-Sourced Aggregates

Embed a base type, register typed event handlers, and let the framework handle versioning, persistence, and replay.

Fully utilizes Go 1.20+ Generics for type-safe, blazing fast execution without the overhead of reflection.

Dispatch and handle commands with full generic type safety. Cleanly separate your read and write models.

Build read models with continuous tailing. Decouple your write-path from your read-path entirely.

Coordinate long-running processes across services with Temporal integration—durable commands, timeouts, and explicit compensation.

In-memory backends for testing ready to go. Easily swap to MySQL or Redis for production workloads.
