SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers working with the Webiny framework need to know which event-publishing abstractions exist and where to import them from, but discovering the correct interfaces and source files requires digging through the codebase.

Core Features & Use Cases

  • Abstraction Catalog: Lists the DomainEvent base class and EventPublisher abstraction with exact import paths and source file locations.
  • Implementation Guidance: Points to related pattern skills (webiny-use-case-pattern, webiny-event-handler-pattern) for wiring up event handlers.
  • Use Case: When building a Webiny API feature that must notify other parts of the system after an action, look up EventPublisher here, read the source file for exact types, and publish a custom DomainEvent subclass to registered handlers.

Quick Start

Show me the Webiny event publisher abstractions and how to import EventPublisher to publish a domain event.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I publish domain events in a Webiny API?▼

Import EventPublisher from webiny/api/event-publisher and call it with a subclass of DomainEvent. The publisher dispatches the event to all registered handlers in the Webiny API layer.

What is the DomainEvent class in Webiny?▼

DomainEvent is the base class for all domain events in Webiny, defined in @webiny/api-core/features/eventPublisher. You extend it to create custom events that EventPublisher can dispatch.

Where do I import EventPublisher from in Webiny?▼

Import it with: import { EventPublisher } from "webiny/api/event-publisher". The underlying source lives in @webiny/api-core/features/eventPublisher/index.ts, which you should read for exact types.

Does Webiny event publishing include handler implementation patterns?▼

The catalog itself only lists abstractions and import paths. For implementation patterns, it directs you to the webiny-use-case-pattern and webiny-event-handler-pattern skills.

What are the limitations of the Webiny event publisher catalog?▼

It covers only two abstractions, DomainEvent and EventPublisher, and does not include executable code or handler registration logic. You must read the referenced source files to get exact interfaces before coding.
