hirestime

hirestime is a thin wrapper around the common time measuring APIs (node and the browser). Uses process.hrtime() on node, the performance API in the browser and falls back to Date if neither is available.

Installation

npm install hirestime

hirestime()

returns a function:

returnedFunction()

Returns the elapsed time since the call of hirestime in milliseconds.

Examples

By default the time is measured in milliseconds:

import hirestime from 'hirestime'

//startpoint of the time measurement
const getElapsed = hirestime()

setTimeout(_ => {
    //returns the elapsed milliseconds
    console.log(getElapsed())
}, 1000)

Specify the unit:

import hirestime from 'hirestime'

//startpoint of the time measurement
const getElapsed = hirestime()

setTimeout(_ => {
   //returns the elapsed seconds
   console.log(getElapsed.s())
   console.log(getElapsed.seconds())

   //returns the elapsed milliseconds
   console.log(getElapsed.ms())
   console.log(getElapsed.milliseconds())

   //returns the elapsed nanoseconds
   console.log(getElapsed.ns())
   console.log(getElapsed.nanoseconds())
}, 1000)
