This utility provides functions to convert color and dates between different formats in JavaScript & TypeScript.

Date conversion

• Import the common-util-kit package into your project.
• Call the desired function from your code to convert dates as needed.

import { ConvertDate } from "common-util-kit";

const convertedDate = ConvertDate.fromTimestamp({
    timeStamp: "1970-01-01",
    format: "DD-MM-YYYY",
});

Color conversion

import { ConvertColor } from "common-util-kit";

const rgba = ConvertColor.hexToRGBA("#FFF", 0.5);

const hexColor = ConvertColor.rgbaStringToHEX("rgba(255, 0, 10, 0.5)");

const hexColor = ConvertColor.rgbToHex({ r: 255, g: 200, b: 100 });

Pub Sub pattern

The Pub/Sub (Publish/Subscribe) pattern is a messaging pattern used in software architecture to enable communication between components in a loosely coupled manner. It allows for the creation of scalable and flexible systems where publishers and subscribers are decoupled from each other. Here's an overview of how the Pub/Sub pattern works

• Subscribe to an event

import { useEffect } from 'react';
import { pubsub } from 'common-util-kit';

useEffect(() => {
     const subscription = pubsub.subscribe("event", (event, ...args) => {});
     
     return () => {
         subscription.unsubscribe();
     }
}, []);

• Publish an event

import { pubsub } from 'common-util-kit';

pubsub.publish("event", ...args);

Iterator pattern

It provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation

• Usage

import { Iterator } from 'common-util-kit';

const array = [1,2,3,4,...];

const iterator = new Iterator(array);

while(iterator.hasNext()){
    console.log(iterator.next());
}
