Countdown Library

Features

• Written in TypeScript.
• Can be used with any JS library or framework.
• Uses (setInterval).
• Easy to use callback method.
• Return values include days, hours, minutes and seconds.

Example

import { Countdown, RemainingTimeType } from 'countdown-lib';

// Any JavaScript supported date format can be used as long as it is passed as a Date object.
const countdown = new Countdown(new Date(2023, 0, 1, 0, 0, 0));

countdown.startCounter((remainder: RemainingTimeType, isComplete: boolean) => {
  // isComplete will return false when all values are zero.
  if (!isComplete) {
    console.log(remainder);
    // Remainder should look something like this:
    // { days: 45, hours: 5, minutes: 32, seconds: 12 }
  }
});

API

// Starts a instance of setInterval that executes a callback every 1000ms with arguments
// for the remaining time and a truthy value that tells you when the countdown is complete.
countdown.startCounter(callback(remainder: RemainingTime, isComplete: boolean) => void): void;

countdown.stopCounter()

// Clears setInterval
countdown.stopCounter(): void

countdown.getRemainingTime()

// Optional method for retrieving remaining time outside of the .startCounter() callback.
// The return type can change depending on your configuration see "config" bellow.
countdown.getRemainingTime(): RemainingTime<number | string>

Config

// You can pass an optional configuration object as a second argument.
const countdown = new Countdown(new Date(2023, 0, 1, 0, 0), config);

addLeadingZeros: boolean

// Adds a left padding of 0 to all values less then 10
const countdown = new Countdown(new Date(2023, 0, 1, 0, 0), { addLeadingZeros: true });
// example: { days: 09, hours: 05, minutes: 02, seconds: 07 }
