React Countdown In ReactJS

React Countdown is a popular library that allows you to add countdown timers to React applications. A countdown timer is a UI element that displays the time remaining until a certain event occurs, such as the expiration of a promotion or the start of a live event. In this blog, we’ll look at how to use React Countdown to add countdown timers to a React app.

To start, you’ll need to install the react-countdown library, which provides the components and functions you’ll need to add countdown timers to your React app. You can install it using npm or yarn:

npm install react-countdown


yarn add react-countdown

Once you’ve installed the library, you can use the Countdown component from react-countdown to add a countdown timer to your app. The Countdown component takes a number of props that allow you to customize the appearance and behavior of the countdown timer.

Here’s an example of how to use the Countdown component to add a countdown timer to a React app:

import { Countdown } from 'react-countdown';

function App() {
  const renderer = ({ days, hours, minutes, seconds, completed }) => {
    if (completed) {
      return <span>The countdown has completed!</span>;
    } else {
      return (
          {days} days {hours} hours {minutes} minutes {seconds} seconds

  return (
      date={new Date('2022-01-01T00:00:00')}

In the example above, the Countdown component is set to countdown to the new year (2022-01-01). The renderer prop is used to specify a function that will be called to render the countdown timer. The function is passed an object containing the time remaining in various units (days, hours, minutes, seconds) and a completed flag that indicates whether the countdown has completed.

You can customize the appearance and behavior of the Countdown component using the various props it supports. For example, you can use the intervalDelay prop to specify how often the countdown timer should update, and the format prop to specify the format of the countdown timer. You can read more about the available props in the react-countdown documentation.

That’s a basic overview of how to use react-countdown to add countdown timers to a React application. You can use it to build a variety of countdown-based features into your app, such as promotion timers, event timers, or other time-sensitive features.
