update-event

Updates an existing event in the store. For events expanded from a recurrence rule, mode controls whether the edit applies to one occurrence or to that occurrence and every later one.

Usage

type UpdateEventPayload = {
	id: EventID;
	event: Partial<CalendarEvent>;
	mode?: "single" | "following";
	originalDate?: string;
};

Field	Type	Description
id	string | number	Target event id.
event	Partial<CalendarEvent>	Fields to update; merged into the stored event.
mode	"single" | "following"	For recurring events: "single" affects one occurrence, "following" this one and later ones.
originalDate	string	Original occurrence date for recurring edits, used to identify the affected instance.

Trigger

api.exec("update-event", {
	id: 7,
	event: { text: "Renamed" },
});

Observe

api.on("update-event", p => console.log("updated", p.id, p.event));

Intercept

api.intercept("update-event", p => p.event.text !== "");

Returning false cancels the update before it reaches the store.

Component handler

<Calendar
  events={[]}
  date={new Date()}
  onupdateevent={p => console.log(p.id, p.event, p.mode)}
/>
