fetchStart property

double get fetchStart

The fetchStart read-only property represents a DOMHighResTimeStamp immediately before the browser starts to fetch the resource.

If there are HTTP redirects, the property returns the time immediately before the user agent starts to fetch the final resource in the redirection.

Unlike many other PerformanceResourceTiming properties, the fetchStart property is available for cross-origin requests without the need of the HTTP response header.

Implementation

external double get fetchStart;
