v0.2.0

Domain Events

Add fire-and-forget domain events via NATS JetStream.

New exports

• DomainEvent — event type with id, domain, type, orgId, and payload
• EventHandler — handler signature (context, event) => Promise<void>

New methods on Kmicro

• publish(event) — publishes to {prefix}.{orgId}.{domain} with JetStream deduplication via msgID
• subscribe(streamName, consumerName, handler) — consumes from an existing JetStream stream/consumer with ack/nak/term semantics

Details

• Subject convention: {prefix}.{orgId}.{domain} (prefix configurable via constructor options, default "events")
• OTel tracing: producer spans on publish, consumer spans on subscribe
• Streams and consumers are created in infrastructure, not by kmicro
• On handler error → nak() (JetStream retries), on unmarshal failure → term() (no retry)
• New dependency: @nats-io/jetstream@3.3.1
