Event Sourcing

A javascript module developed to easily manage event sourcing.

It's compose of two sub-modules:

• eventStore
• eventBroker

The blueprint of the infrastructure is based on push notifications of the event store towards every event broker that must work as a persistent queue. Basically each new event that is stored in the event store, is published into each subscribed event broker.

New: Event Store transaction support!

Starting from v3.0.0 some major stability improvements were made.
A part from that it's great to announce transaction support for the supported Event Store implementations.

Now you case save multiple events belonging to the same or different event streams in a transactional way. For more information visit the dedicated documentation.
