Note: Since our focus is on learning about the date-fns library, we will keep this project beginner-friendly and not create separate components.Īt the top of a JSX file, we will import the necessary hooks, functions, and components:Ĭonst now = new Date ( ) const endOfToday = endOfDay (now ) const initialEndDate = localStorage. differenceInMilliseconds: Calculates the difference between two dates in milliseconds.endOfDay: Returns the end of the day for the given date.add: Adds a specified amount of time to a given date.addDays: Adds a specified number of days to a given date.isBefore: Determines if the first date is before the second date.intervalToDuration: Calculates the duration between two dates as a duration object.formatDuration: Converts a duration object to a human-readable string.format: Formats a date according to the given format string.Unlike other libraries, there's no need to import everything, making date-fns a fast and convenient solution for working with dates!įor the countdown clock app, we will use the following eight functions from the date-fns library: The date-fns library alleviates the burden of managing dates, allowing you to focus on other aspects of your projects.Īn additional benefit of this library is that it enables you to import only the functions required for your project, resulting in a smaller app that loads faster. JavaScript is notorious for its poor date support when it comes to writing date-related functions. It helps you format, parse, compare, and manipulate dates in a user-friendly way. So, what is the date-fns library? The date-fns library is a collection of functions that makes it easy to work with dates and times in a React application. However, feel free to clone the project or copy the CSS code. Note: We will be focusing on learning React code, not CSS. By the end of this tutorial, you will have a functional countdown app that demonstrates the power and convenience of the date-fns library. We will discuss the essential functions of the date-fns library, the benefits of using it for date manipulation, and how to incorporate it into your React application. This step-by-step tutorial will guide you through the process of building a user-friendly countdown timer that allows users to set an end date and watch as the timer counts down to zero. In this article, we will explore how to create a countdown app using React and the date-fns library. This article explores the date-fns library, a powerful and convenient tool for managing dates and times in your applications, featuring step-by-step instructions for creating a countdown React app!
