HowLongDidItTake

Measure elapsed time.

• Simple. Lightweight. TypeScript friendly. Small bundling size.
• Format the result. Choose s, ms or ns. Even automatically.
• Limit the precision or the fraction digits.
• Available on both Node.js and browsers (maybe).

CLI

Use hldit command.

hldit (any command)

hldit (any *.js filepath)

• On CLI, the unit is determined automatically and the precision is always 2. I.e. just like autoUnit(2) via the API (see below).
• If a given JavaScript file has a default export of any Promise type, hldit awaits until the Promise is resolved.

API

Import

import * as hldit from "howlongdidittake";

Stopwatch

const getElapsedTime = hldit.stopwatch.autoUnit(2); // give precision
console.log(getElapsedTime());

const getElapsedTime = hldit.stopwatch.withUnit("ms", 2); // give unit and fraction digits
console.log(getElapsedTime());

Measure

const anyAsyncCallback = () => Promise.resolve();

const measure = hldit.measure.autoUnit(2); // give precision
measure(anyAsyncCallback).then((elapsedTime) => console.log(elapsedTime));

const anyAsyncCallback = () => Promise.resolve();

const measure = hldit.measure.withUnit("ms", 2); // give unit ant fraction digits
measure(anyAsyncCallback).then((elapsedTime) => console.log(elapsedTime));

hldit.measure has functions for sync callbacks as well.
