read onlydomContentLoadedEventEnd:Float

A DOMHighResTimeStamp representing the time value equal to the time immediately after the current document's DOMContentLoaded event completes.

read onlydomContentLoadedEventStart:Float

A DOMHighResTimeStamp representing the time value equal to the time immediately before the user agent fires the DOMContentLoaded event at the current document.

Inherited Variables

Defined by PerformanceResourceTiming

read onlyconnectEnd:Float

A DOMHighResTimeStamp immediately after the browser finishes establishing the connection to the server to retrieve the resource.

read onlyconnectStart:Float

A DOMHighResTimeStamp immediately before the browser starts to establish the connection to the server to retrieve the resource.

read onlydecodedBodySize:Int

A number that is the size (in octets) received from the fetch (HTTP or cache) of the message body, after removing any applied content-codings.

read onlydomainLookupEnd:Float

A DOMHighResTimeStamp representing the time immediately after the browser finishes the domain name lookup for the resource.

read onlydomainLookupStart:Float

A DOMHighResTimeStamp immediately before the browser starts the domain name lookup for the resource.

read onlyencodedBodySize:Int

A number representing the size (in octets) received from the fetch (HTTP or cache), of the payload body, before removing any applied content-codings.

read onlyfetchStart:Float

A DOMHighResTimeStamp immediately before the browser starts to fetch the resource.

read onlyinitiatorType:String

A DOMString representing the type of resource that initiated the performance entry, as specified in PerformanceResourceTiming.initiatorType.

read onlynextHopProtocol:String

A DOMString representing the network protocol used to fetch the resource, as identified by the ALPN Protocol ID (RFC7301).

read onlyredirectEnd:Float

A DOMHighResTimeStamp immediately after receiving the last byte of the response of the last redirect.

read onlyredirectStart:Float

A DOMHighResTimeStamp that represents the start time of the fetch which initiates the redirect.

read onlyrequestStart:Float

A DOMHighResTimeStamp immediately before the browser starts requesting the resource from the server.

read onlyresponseEnd:Float

A DOMHighResTimeStamp immediately after the browser receives the last byte of the resource or immediately before the transport connection is closed, whichever comes first.

read onlyresponseStart:Float

A DOMHighResTimeStamp immediately after the browser receives the first byte of the response from the server.

read onlysecureConnectionStart:Float

A DOMHighResTimeStamp immediately before the browser starts the handshake process to secure the current connection.

read onlyserverTiming:Array<PerformanceServerTiming>

An array of PerformanceServerTiming entries containing server timing metrics.

read onlytransferSize:Int

A number representing the size (in octets) of the fetched resource. The size includes the response header fields plus the response payload body.

read onlyworkerStart:Float

Returns a DOMHighResTimeStamp immediately before dispatching the FetchEvent if a Service Worker thread is already running, or immediately before starting the Service Worker thread if it is not already running. If the resource is not intercepted by a Service Worker the property will always return 0.

Defined by PerformanceEntry

read onlyduration:Float

A DOMHighResTimeStamp representing the time value of the duration of the performance event.

read onlyentryType:String

A DOMString representing the type of performance metric such as, for example, "mark". See property page for valid values.

read onlyname:String

A value that further specifies the value returned by the PerformanceEntry.entryType property. The value of both depends on the subtype. See property page for valid values.

read onlystartTime:Float

A DOMHighResTimeStamp representing the starting time for the performance metric.
