Event type
An event type is a label or specification that identifies the category and associated characteristics of an event handled or recorded by a system.
Web Components in Action
An event type is a string identifier that distinguishes the kind of event delivered through an event system.
- How it is used
- Identifies events so event buses and DOM listeners can route callbacks to the intended handlers.
- How deep it goes
- Defines event types as strings, explains naming collisions, and demonstrates shared constants without descending into event-system internals.
- Examples
- Uses a workout player's onPlaylistTimeUpdate listener and a workout plan's dispatched CustomEvent with timing details.
- What you can do after
- Apply event types via an event bus and CustomEvent, including reusable static getters for shared names.
Kafka for Architects
An event type is a reusable specification that bundles predefined characteristics for a class of events or topics.
- How it is used
- Standardizes recurring Kafka topic characteristics and supports catalogue-based governance for business and technical topics.
- How deep it goes
- Defines bundled characteristics and related requirements but stops short of implementation walkthroughs or language-specific configuration.
- Examples
- Uses new business events, repartitioning intermediates, and catalogue entries as concrete examples.
- What you can do after
- Apply it via an event catalogue to select consistent topic characteristics and include technical topics in governance.
