public class PerformanceResourceTiming
extends PerformanceEntry

The PerformanceResourceTiming interface enables retrieval and analysis of detailed network timing data regarding the loading of an application's resources. An application can use the timing metrics to determine, for example, the length of time it takes to fetch a specific resource, such as an XMLHttpRequest, <SVG>, image, or script.

Method Detail

connectEnd

@JsProperty(name="connectEnd")
public double connectEnd()

The connectEnd read-only property returns the timestamp immediately after the browser finishes establishing the connection to the server to retrieve the resource. The timestamp value includes the time interval to establish the transport connection, as well as other time intervals such as SSL handshake and SOCKS authentication.

PerformanceResourceTiming.connectEnd - MDN, connectEnd - Resource Timing Level 1

connectStart

@JsProperty(name="connectStart")
public double connectStart()

The connectStart read-only property returns the timestamp immediately before the user agent starts establishing the connection to the server to retrieve the resource.

See Also:

PerformanceResourceTiming.connectStart - MDN, connectStart - Resource Timing Level 1

decodedBodySize

@JsProperty(name="decodedBodySize")
public int decodedBodySize()

The decodedBodySize read-only property returns the size (in octets) received from the fetch (HTTP or cache) of the message body, after removing any applied content-codings. If the resource is retrieved from an application cache or local resources, it returns the size of the payload after removing any applied content-codings.

See Also:

PerformanceResourceTiming.decodedBodySize - MDN, decodedBodySize - Resource Timing Level 2

domainLookupEnd

@JsProperty(name="domainLookupEnd")
public double domainLookupEnd()

The domainLookupEnd read-only property returns the timestamp immediately after the browser finishes the domain name lookup for the resource.

See Also:

PerformanceResourceTiming.domainLookupEnd - MDN, domainLookupEnd - Resource Timing Level 1

domainLookupStart

@JsProperty(name="domainLookupStart")
public double domainLookupStart()

The domainLookupStart read-only property returns the timestamp immediately before the browser starts the domain name lookup for the resource.

See Also:

PerformanceResourceTiming.domainLookupStart - MDN, domainLookupStart - Resource Timing Level 1

encodedBodySize

@JsProperty(name="encodedBodySize")
public int encodedBodySize()

The encodedBodySize read-only property represents the size (in octets) received from the fetch (HTTP or cache), of the payload body, before removing any applied content-codings.

See Also:

PerformanceResourceTiming.encodedBodySize - MDN, encodedBodySize - Resource Timing Level 2

fetchStart

@JsProperty(name="fetchStart")
public double fetchStart()

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

See Also:

PerformanceResourceTiming.fetchStart - MDN, fetchStart - Resource Timing Level 1

initiatorType

@JsProperty(name="initiatorType")
 @Nonnull
public java.lang.String initiatorType()

The initiatorType read-only property is a string that represents the type of resource that initiated the performance event.

See Also:

PerformanceResourceTiming.initiatorType - MDN, initiatorType - Resource Timing Level 1

nextHopProtocol

@JsProperty(name="nextHopProtocol")
 @Nonnull
public java.lang.String nextHopProtocol()

The nextHopProtocol read-only property is a string representing the network protocol used to fetch the resource, as identified by the ALPN Protocol ID (RFC7301).

See Also:

PerformanceResourceTiming.nextHopProtocol - MDN, nextHopProtocol - Resource Timing Level 2

redirectEnd

@JsProperty(name="redirectEnd")
public double redirectEnd()

The redirectEnd read-only property returns a timestamp immediately after receiving the last byte of the response of the last redirect.

requestStart

@JsProperty(name="requestStart")
public double requestStart()

The requestStart read-only property returns a timestamp of the time immediately before the browser starts requesting the resource from the server, cache, or local resource. If the transport connection fails and the browser retires the request, the value returned will be the start of the retry request.

PerformanceResourceTiming.requestStart - MDN, requestStart - Resource Timing Level 1

responseEnd

@JsProperty(name="responseEnd")
public double responseEnd()

See Also:

PerformanceResourceTiming.responseEnd - MDN, responseEnd - Resource Timing Level 1

responseStart

@JsProperty(name="responseStart")
public double responseStart()

The responseStart read-only property returns a timestamp immediately after the browser receives the first byte of the response from the server, cache, or local resource.

secureConnectionStart

@JsProperty(name="secureConnectionStart")
public double secureConnectionStart()

The secureConnectionStart read-only property returns a timestamp immediately before the browser starts the handshake process to secure the current connection. If a secure connection is not used, the property returns zero.

See Also:

PerformanceResourceTiming.secureConnectionStart - MDN, secureConnectionStart - Resource Timing Level 1

transferSize

@JsProperty(name="transferSize")
public int transferSize()

The transferSize read-only property represents the size (in octets) of the fetched resource. The size includes the response header fields plus the response payload body (as defined by RFC7230).

workerStart

@JsProperty(name="workerStart")
public double workerStart()

The workerStart read-only property of the PerformanceResourceTiming interface 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.
