Time Measurer
Time Measurer is a simple wrap for process.hrtime.bigint to measure time with procession and express that time easily through formatted representations, anytime you want to express how much a query or a request took at code level you may want to give this a try.
Install
npm install @universal-packages/time-measurerGlobal methods
startMeasurement()
Creates a new TimeMeasurer instance to start a measurement.
import { startMeasurement } from '@universal-packages/time-measurer'
async function getAll() {
const measurer = startMeasurement()
const data = await myDB.getAllRecords()
const measurement = measurer.finish()
console.log('All records - ', measurement.toString())
}
getAll()
// > All records - 2.23mssleep(milliseconds: number)
Time measurer ships with a convenient sleep function that takes a single parameter time in milliseconds, internally it is just a promise with a timeout that resolves it.
import { sleep } from '@universal-packages/time-measurer'
async function awaitable() {
await sleep(2000)
}TimeMeasurer
Class TimeMeasurer provides an instantiable interface to start measuring time from any part of your code. The measurement starts at instancing time.
import { TimeMeasurer } from '@universal-packages/time-measurer'
async function getAll() {
const measurer = new TimeMeasurer()
measurer.start()
const data = await myDB.getAllRecords()
const measurement = measurer.finish()
console.log('All records - ', measurement.toString())
}
getAll()
// > All records - 2.23msInstance methods
start()
Resets the initial time.
stop()
Returns a measurement representing the time passed from when start was called.
Measurement
A Measurement object is the time representation after a measure, it provides the interface to express time as a formatted string or even as a date object.
Instance methods
toString(format: TimeFormat)
Get the time representation as a string, this function takes one param TimeFormat, that can be one of Condensed, Human, Expressive, default: Human.
Example output
2hrs 35min 51.235sec
2:35:51.235
2hrs 35min 51.235sec
2 Hours, 35 Minutes, and 51.235 Seconds
It will take into account parts of the representation that are not contributing to the time, like if the measurement only took seconds, minutes and hours will not be included.
51.235sec
51.235
51.235sec
51.235 Seconds
toDate()
Get the time representation as a date object this can be helpful if you want to use the Date api to format or do whatever with the date.
