# Event — Event-Driven Architecture Reference Quick-reference skill for event-driven architecture, event sourcing, pub/sub patterns, and stream processing. ## When to Use - Designing event-driven microservice architectures - Implementing pub/sub or event bus patterns - Building event sourcing and CQRS systems - Choosing between event brokers (Kafka, RabbitMQ, etc.) - Handling event ordering, idempotency, and exactly-once semantics ## Commands ### `intro` ```bash scripts/script.sh intro ``` Overview of event-driven architecture — patterns, benefits, and tradeoffs. ### `patterns` ```bash scripts/script.sh patterns ``` Core patterns — pub/sub, event sourcing, CQRS, saga, choreography. ### `design` ```bash scripts/script.sh design ``` Event design — naming, schema, versioning, and payload structure. ### `brokers` ```bash scripts/script.sh brokers ``` Event broker comparison — Kafka, RabbitMQ, NATS, Pulsar, SQS, EventBridge. ### `sourcing` ```bash scripts/script.sh sourcing ``` Event sourcing deep dive — event store, projections, snapshots. ### `delivery` ```bash scripts/script.sh delivery ``` Delivery guarantees — at-most-once, at-least-once, exactly-once. ### `stream` ```bash scripts/script.sh stream ``` Stream processing — windowing, aggregation, and real-time analytics. ### `checklist` ```bash scripts/script.sh checklist ``` Event-driven architecture checklist. ### `help` ```bash scripts/script.sh help ``` ### `version` ```bash scripts/script.sh version ``` ## Configuration | Variable | Description | |----------|-------------| | `EVENT_DIR` | Data directory (default: ~/.event/) | --- *Powered by BytesAgain | bytesagain.com | hello@bytesagain.com*
