UI components can trigger reactions on an Event. Event triggers differ according to the component. For example, a button component can trigger a reaction on a click event, and a table component event can trigger a reaction on a page change or table row click event. To see what event triggers are available for a given component, see Components.
An event can set the state of a UI component, open or close a modal, trigger another query, or even run custom JavaScript.
For example, the GitHub PR summarizer blueprint uses a Summarize button with an event that triggers on a click. The event uses the Trigger Query reaction which runs the summarizePulls query.
