Getting Started

There are two ways of using this package - setting HTML elements or mounting it through vanilla JS

You can construct you countdown by setting HTML tags with its necessary and optional data attributes or you can create a custom countdown with vanilla JS and append your on-the-fly countdown element in the container tag of your choice. Or you can also use both of them. Finally, just call the counter() method.

Make sure you have node installed

Just make sure you have the node and npm installed. You can check it by running the following commands:

node -v
# Expected return: v12.18.4 (or a more recent version)

npm -v
# Expected return: v6.14.8 (or a more recent version)

Install the package as a dependency

The first step is to install this package as a dependency:

npm i dynamic-countdown --save

Using HTML data attributes

In order to use the Dynamic Countdown by using data attributes, you just need to follow those 2 simple steps:

Call the script module to your HTML

Before closing the body tag, just add the following code snippet:

<script type="module" src="./node_modules/dynamic-countdown/index.js"></script>

Create your own counter element

It is necessary that your countdown component uses the counter class and also to declare some specific data attributes.

Then you must add its children, according to the date format desired.

Counter Container

The required data attributes are (default values for optional attributes in bold):

Counter Children

Within the container, you must create children elements to show each desired time unit. Each children must have the counter__unit class declared.

And you must also declare each children elements time unit by declaring the data-time-unit attribute, that can have the following values: days , hours , minutes and/or seconds .

Example

Here is a simple example:

<p class="counter" data-target-date="12/31/2021 23:59" data-time-format="DHMS" data-min-digits="2" data-lang="en">
    <span data-unit="days" class="counter__unit"></span>
    <span data-unit="hours" class="counter__unit"></span>
    <span data-unit="minutes" class="counter__unit"></span>
    <span data-unit="seconds" class="counter__unit"></span>
</p>

And another example, with the minimum required data-attributes:

<p class="counter" data-target-date="12/31/2021 23:59">
    <span data-unit="days" class="counter__unit"></span>
    <span data-unit="hours" class="counter__unit"></span>
    <span data-unit="minutes" class="counter__unit"></span>
    <span data-unit="seconds" class="counter__unit"></span>
</p>

Using vanilla JS method

You can create as many counters as you want to by using the mountCounter method. Then, you must call the counter method on you main file.

Import

Firstly, you must import the counter to your file:

import { mountCounter } from 'dynamic-countdown'

MountCountdown

Now you must call the mountCountdown method and append the mounted countdown to the HTML element you need:

// Creating the countdown
const myCountdown = mountCounter('08/01/2021 16:20', 'DH', '2', 'en', 'primary-light-inverted')
// Appending it to the main HTML tag
document.querySelector('main').appendChild(myCountdown)

Running the Countdown

On your main file, you must import the counter method and execute it after window loads:

import { counter } from 'dynamic-countdown'
window.onload = () => {
    counter()
}

Style Theme

You can also add extra classes in order to take advantage of the dynamic-countdown theme.

In order to use the dynamic-countdown theme you must add its style too (right before the closing head tag):

<link rel="stylesheet" href="./node_modules/dynamic-countdown/style/style.min.css">

Or you may use this other link: https://marcelo-diament.github.io/dynamic-countdown/style/style.min.css .
