request-data

Emitted by the store when the visible date range changes (Pro). It is notification-only - there's no built-in store handler. Subscribers such as RestDataProvider or a DynamicLoader catch it, fetch events for that range, and push them back with provide-data.

Usage

type RequestDataPayload = {
	startDate: Date;
	endDate: Date;
	date: Date;
	view: string;
};

Field	Type	Description
startDate	Date	Start of the visible range (inclusive).
endDate	Date	End of the visible range (exclusive).
date	Date	Current pivot date of the view.
view	string	Active view id ("day", "week", "month", ...).

The range is half-open: [startDate, endDate). The action fires only when startDate or endDate actually changes - a view switch that computes the same range emits nothing. The initial range is replayed after the init callback, so a provider attached there with api.setNext still receives the first request.

Observe

api.on("request-data", ({ startDate, endDate }) => {
	loadEvents(startDate, endDate);
});

Component handler

<Calendar onrequestdata={p => loadEvents(p.startDate, p.endDate)} />
