Despite lodash and many functionalities out there, there are still some utilities didn't achive what I intend to have.

Usage no npm install needed!

JS Library (utilzed)

Despite lodash and many functionalities out there, there are still some utilities didn't achive what I intend to have.


npm install utilzed


# set specific version
npm install utilzed@0.2.3


This library has both flow and ts declarations

For compiled library:

import utilzed from 'utilzed';

// for promise module and functions
const { waitForTrue, sleep } = utilzed.promise;

// for timeconvert module
const { TimeConverter, Format } = utilzed.timeconvert;

// If index module getting too big for the size you can import specific module
import timeconvert from 'utilzed/dist/timeconvert';

Important for pure ES6 (require)

// If uses require function you will need to use .default
// For import in typescript or flow, this is not required

const utilzed = require('utilzed').default;
const timeconvert = require('utilzed/dist/timeconvert').default;

Library Functions:

This library has jsdoc generated comment.

Promise Related:


In case you might be polling for a condition before proceed:

import utilzed from 'utilzed'
// import waitForTrue from 'utilzed/dist/promise/waitForTrue'

const checkCondition = async () => (await somePollCheckFunction());

// this will waitForTrue checkCondition to be true
// checkCondition will be called every 100ms
const success = await utilzed.waitForTrue(100, checkCondition, 1000);

if (success) {
  // Meaning checkCondition function returns true before 1000 ms

// meaning after 1000ms the checkCondition returns false still
// handle unsuccessful poll for true


await sleep(100) will await for 100ms before proceed to next function

import utilzed from 'utilzed'

await utilzed.sleep(100);

// will proceed after sleep for 100 ms

Validation Related:


This will return true if object is empty, string is empty, number is 0 or array is empty

import utilzed from 'utilzed'

// if lodash isEmpty the following will return true
utilzed.isEmptyOrZero(100); // returns false
utilzed.isEmptyOrZero(0); // returns true


This module checks if the versioning meets the condition

import utilzed from 'utilzed'

const { OPERATORS, isVersionValid } = utilzed.versionCheck

// this will return true
isVersionValid('v2.1.1', OPERATORS.MORE_THAN_EQUAL, 'v1.1.1')

// this will return false
isVersionValid('v1.1.1', OPERATORS.LESS_THAN, 'v1.1.1')



Convert time value without mathematical headache

import utilzed from 'utilzed'

// Can use destructured assignment
const { TimeConverter, Format } = utilzed.timeconvert;

// returns 123000 (target in ms) from 123 (seconds)
TimeConverter.target(Format.MILISECONDS).from(Format.SECONDS, 123);
