qol

Are you tired of making the same module in every project? Not a problem! Qol has your back.

A suite of random but useful functions that are aimed at giving you 'piece of cake' level comfortability.

This package is also available as:

• qolpy • py
• qolrus • rust

Importing

// ES6 Module
import * as qol from "@techtronics/qol";

// ES6 Destructuring
import { randomColour } from "@techtronics/qol";

// ES5 Module
const qol = require("@techtronics/qol");

// ES5 Destructuring
const { randomColour } = require("@techtronics/qol");

Functions

randomColour

Get a random colour; For those scenarios where you couldn't care less!

Returns a string

const c = randomColour();
const cRGB = randomColour("rgb");
const cCMYK = randomColour("cmyk");
const cHSV = randomColour("hsv");
const cHSL = randomColour("hsl");

console.log(c, cRGB, cCMYK, cHSV, cHSL);
// #f7f7f7, rgb(247,247,247), cmyk(0%,0%,0%,3%), hsv(0,0%,97%), hsl(0,0%,97%)

Params

Parameter	Default Setting	Required?	Definition	Options
setting	hex	No	The type of colour you would like returned	hex, rgb, cmyk, hsv, hsl

parseDate

Send in date parameters and receive either an object with their metadata, or a parsed date (e.g 2 Sep 2020); American formatting is possible (e.g Sep 2 2020).

NOTE: You do not need to add 1 to the day or month, it will do that for you.

Returns a string or DateObject

const d = new Date();

const dateArr = [d.getDate(), d.getDay(), d.getMonth(), d.getFullYear()];

const pD = parseDate(...dateArr, "nll", true);
const pDfull = parseDate(...dateArr, "lll");

console.log(pD, pDfull);
// October 24 2022, Monday 24th October 2022

interface

interface DateObject {
	day: {
		short: string;
		long: string;
		ordinalMonth: string;
		ordinalWeek: string;
		weekNumber: number;
		monthNumber: number;
	};
	month: {
		short: string;
		long: string;
		ordinal: string;
		number: number;
	};
	year: {
		short: number;
		long: number;
	};
}

Params

Parameter	Default Setting	Required?	Definition	Options
monthDay	none	Yes	The day of the month	type number
weekDay	none	Yes	The day of the week	type number
month	none	Yes	The numeric month	type number
year	none	Yes	The full numeric year	type number
format	none	No	The date format you would like	n = numeric, s = shorthand text, l = full text; nns, nnl, sss, ssl, lll, nss, nsl, nls, nll
american	false	No	Whether or not you would like the format to be 'Americanised'	true, false

numParse

Convert a number into a string as if it's MS Excel!

Returns a string

const num = numParse(2100.45, "space");
const numEurope = numParse(2100.45, "punct");
const numCustom = numParse(2100.45, "-" as any);

console.log(num, numEurope, numCustom);
// 2 100.45, 2.100,45, 2-100.45)

Params

Parameter	Default Setting	Required?	Definition	Options
value	undefined	Yes	The number you want to be parsed	none
setting	comma	No	The delimiter for the number	space, comma, punct, any other delimiter as a string

Logger

Log code executions, stats, and processing times in any framework in any environment; and chain the logs to see the entire process in the terminal!

Returns void

code example

import { Logger } from "@cerebrusinc/qol";
import someFunction from "./someFunction";
import { express } from "express";

const app = express();
logger = new Logger();

app.use((req, res, next) => {
	logger.newLog("log", req.method, req.path);
	logger.log("log", "someFunction", "Doing something...");
	someFunction();
	logger.procTime();
	next();
	logger.execTime();
});
// rest of your code

terminal output

[log • aGy5Op]: GET => /hello | 07/10/2023, 2:46:19 am
[log • aGy5Op]: someFunction => Doing something... | 07/10/2023, 2:46:20 am
[stats • aGy5Op]: someFunction => 53ms
[exec • aGy5Op]: 121ms

Variables

Variable	Default Setting	Required?	Definition
idLength	5	No	A number that determines the length of the log id
americanDate	false	No	A boolean that determines whether the parseDate output should be american
locale?	undefined	No	A Intl.LocalesArgument that determines the time locale
timeFormatOptions?	undefined	No	A Intl.DateTimeFormatOptions that sets options for the time output

These can be set when initialising the Logger or dynamically. NOTE that you can initialise any of them as undefined through the constructor and it will set their default values, however, dynamically they will need a value of their type unless they can be undefined.

// Set the americanDate param through the constructor
const logger = new Logger(undefined, true);

// set the americanDate param dynamically
logger.americanDate = false;

Methods

Method	Type	Details
newLog	(config: "stats" or "log" or "error", process: string, message: string) => void	Create a new log chain; This will change the log id
log	(config: "stats" or "log" or "error", process: string, message: string) => void	Add a log to the log chain; This will not change the log id
procTime	() => void	Log the processing time between this call and the previous call to view their processing time
execTime	() => void	View the entire execution time

sleep

Mimics python's time.sleep function when a delay is needed to mimic processes such as an API call.

Returns a Promise<unknown>

const fetchData = async (): Promise<string> => {
	try {
		await sleep(1200);
		return "data";
	} catch {
		return "fetchData error";
	}
};

console.log(fetchData());
// data

You can also mimick an error by setting the error arg to true:

const fetchData = async (): Promise<string> => {
	try {
		// set it to true
		await sleep(1200, true);
		return "data";
	} catch {
		return "fetchData error";
	}
};

console.log(fetchData());
// fetchData error

Params

Parameter	Default Setting	Required?	Definition	Options
value	undefined	Yes	The number you want to be parsed	none
setting	comma	No	The delimiter for the number	space, comma, punct, any other delimiter as a string
