EventCatalog: Building Documentation for Event-Driven Systems
Update: 2025-08-27
Description
Architecture Corner Newsletter Podcast explores the tools and practices that make complex software architectures more manageable and maintainable.
Event-driven applications often struggle with scattered documentation and poor discoverability of their messaging contracts. EventCatalog emerges as an open-source solution that brings order to this complexity through a documentation-as-code approach.
In this episode we will cover:
- The challenges of documenting both synchronous APIs and asynchronous messaging in modern applications
- How EventCatalog organizes domains, services, and messages using a structured file-based approach
- Setting up your first event catalog with commands, events, and queries
- Integrating schema definitions from OpenAPI, AsyncAPI, JSON, and Avro formats
- Managing teams, users, and ownership information within your documentation
- Incorporating Domain-Driven Design concepts like ubiquitous language and entities
- Real-world examples of multi-domain architectures with eCommerce and Fulfillment systems
