Usage in Deno
import { PerformanceResourceTiming } from "node:perf_hooks";
Provides detailed network timing data regarding the loading of an application's resources.
The constructor of this class is not exposed to users directly.
connectEnd: number
The high resolution millisecond timestamp representing the time immediately after Node.js finishes establishing the connection to the server to retrieve the resource.
connectStart: number
The high resolution millisecond timestamp representing the time immediately before Node.js starts to establish the connection to the server to retrieve the resource.
decodedBodySize: number
A number representing the size (in octets) received from the fetch (HTTP or cache), of the message body, after removing any applied content-codings.
domainLookupEnd: number
The high resolution millisecond timestamp representing the time immediately after the Node.js finished the domain name lookup for the resource.
domainLookupStart: number
The high resolution millisecond timestamp immediately before the Node.js starts the domain name lookup for the resource.
encodedBodySize: number
A number representing the size (in octets) received from the fetch (HTTP or cache), of the payload body, before removing any applied content-codings.
entryType: "resource"
fetchStart: number
The high resolution millisecond timestamp immediately before the Node.js starts to fetch the resource.
redirectEnd: number
The high resolution millisecond timestamp that will be created immediately after receiving the last byte of the response of the last redirect.
redirectStart: number
The high resolution millisecond timestamp that represents the start time of the fetch which initiates the redirect.
requestStart: number
The high resolution millisecond timestamp representing the time immediately before Node.js receives the first byte of the response from the server.
responseEnd: number
The high resolution millisecond timestamp representing the time immediately after Node.js receives the last byte of the resource or immediately before the transport connection is closed, whichever comes first.
secureConnectionStart: number
The high resolution millisecond timestamp representing the time immediately before Node.js starts the handshake process to secure the current connection.
transferSize: number
A number representing the size (in octets) of the fetched resource. The size includes the response header fields plus the response payload body.
workerStart: number
The high resolution millisecond timestamp at immediately before dispatching the fetch
request. If the resource is not intercepted by a worker the property will always return 0.
toJSON(): any
Returns a object that is the JSON representation of the PerformanceResourceTiming object
