node-hrtime-ops

🙌 A set of handy-dandy functions to cast, compare and process hrtime tuples.

Install

yarn add node-hrtime-ops

Usage

import { isGreater, toMilliseconds } from "node-hrtime-ops";

const start = process.hrtime();

// do stuff

const elapsed = process.hrtime(start);

if(isGreater(elapsed, [2, 5 * 1E9/2])){ // it will be true only if 2.5 seconds passed
    console.log(`Script evaluation took ${toMilliseconds(elapsed)}ms`);
}

Equations

A common equation operations. Accepts two tuples returned from process.hrtime() or arrays alike that.
Comparison made from left to right, meaning that isGreater(t1, t2) equals t1 > t2.

• isEqual(t1: [number, number], t2: [number, number])=> boolean
• isGreater(t1: [number, number], t2: [number, number])=> boolean
• isGreaterOrEqual(t1: [number, number], t2: [number, number])=> boolean
• isLess(t1: [number, number], t2: [number, number])=> boolean
• isLessOrEqual(t1: [number, number], t2: [number, number])=> boolean

Operations

Basic arithmetic operations as if it were simple numbers.

• add(t1: [number, number], t2: [number, number])=> [number, number]
• subtract(t1: [number, number], t2: [number, number])=> [number, number]

Casts

Transformations between hrtime tuple and numbers.

• toSeconds(t: [number, number])=> number — Transforms tuple to a float, where integer part is seconds, 4ex: casts [1, 2] to 1.000000002.
• toMilliseconds(t: [number, number])=> number — Transforms tuple to a float, where integer part is milliseconds, 4ex: casts [1, 2] to 1000.000002.
• toMicroseconds(t: [number, number])=> number — Transforms tuple to a float, where integer part is microseconds, 4ex: casts [1, 2] to 1000000.002.
• toNanoseconds(t: [number, number])=> bigint — Transforms tuple to a bigint representing nanoseconds, 4ex: casts [1, 2] to 1000000002n.
• fromSeconds(t: number)=> [number, number]
• fromMilliseconds(t: number)=> [number, number]
• fromMicroseconds(t: number)=> [number, number]
• fromNanoseconds(t: bigint)=> [number, number]
