Small, sharp primitives

EquinoxJS centers the model around deciders, folds, services and reactions. You get the core building blocks for event sourced systems without having to adopt a surrounding framework or command bus architecture.

Real deployment coverage

PostgreSQL via MessageDB for relational deployments and DynamoStore for serverless ones.

Store-aware performance

Performance characteristics stay visible at the category boundary. EquinoxJS lets you tune loading and caching behavior explicitly instead of flattening everything into a generic store abstraction.

Operationally honest

Ordering, idempotency, checkpointing and read lag stay explicit in the model. That makes production tradeoffs visible early instead of showing up later as framework-shaped surprises.

Not a framework

You can expose a service API, a command handler API, or both. EquinoxJS has opinions about boundaries, not about your transport or application architecture.

First-class reactions

Reactions and projection helpers cover the common read-model and process-manager patterns without locking you into one shape.
