Timer (for JavaScript)

Custom and more accurate setInterval and setTimeout functionality that is not nerfed for things like when the browser tab is not in focus

Features

• Roughly 99% accurate real time intervals in JavaScript
• More precision than a whole millisecond; fractional values supported
• Alternate version with only whole millisecond precision but with a smaller footprint on the JavaScript Event Loop

Installation

Install via:

npm install @y0urstruly/timer

Usage

JavaScript

• Main Timer Library

const {timeout,interval,wait,clear} = require('@y0urstruly/timer');

• Alternate Timer Library

const {timeout,interval,wait,clear} = require('@y0urstruly/timer/docile');

TypeScript

• Main Timer Library

import {timeout,interval,wait,clear} = from '@y0urstruly/timer';

• Alternate Timer Library

import {timeout,interval,wait,clear} = from '@y0urstruly/timer/docile';

Modules

• interval(userFN:()=>void, ms:number): number: better setInterval, first argument is function, second argument is ms, returns ID
• timeout(userFN:()=>void, ms:number): number: better setTimeout, first argument is function, second argument is ms, returns ID
• wait(ms:number): Promise<void>: all you python sleep using kids, your functionality offered by a promise wrapped around timeout (tldr; await wait(ms))
• clear(ID:number): boolean: removes any interval or timeout by ID. For example clear(timeout(someFN)) is a waste of code since someFN will never run

Disclaimers

• It is more precise in nodejs (>300 events per ms at least on a github codespace)
• It is less precise in a browser (~10 events per ms at least on a chrome tab)
• The 2 points above were determined by comparing a 0ms interval to a 1ms interval and the ratio of their calls
• Of course, sub ms timers might lose precision since functions take time to execute (tested on codespace for 0.2ms and got 98% precision instead) so it is recommended to have fractional timer values greater than 1
• The smaller the fractional part, the less accurate (1.1 would be more accurate than 2.01)
