Choosing the Best React Date Pickers for Modern Development

Date pickers are a staple in modern web applications, providing users with an intuitive interface to select dates. In the React ecosystem, a date picker is not just a luxury but a necessary component, especially when dealing with forms and time-sensitive data.

The right date picker can make or break the user experience, so it's crucial to choose the best react date picker that aligns with your project's needs.

What is a React Date Picker?

A React date picker is a UI component that allows users to easily input dates into a form field. The react datepicker component is a key UI component for handling date inputs in React applications, offering a calendar view from which a date can be selected. It can be integrated into React apps to handle date inputs more efficiently. React date pickers come with various features such as disabling dates, highlighting dates, and much more, making them versatile tools for developers.

Popular React Date Picker Libraries

There are several libraries available for implementing date pickers in React. Each library offers different features and has its own advantages. Some of the most popular libraries include React DatePicker, React Date Range, and React Big Calendar. These libraries offer a range of functionalities from basic date picking to complex date ranges and calendar views.

React DatePicker: A Go-To Library

React DatePicker is one of the most popular libraries among React developers. It is a lightweight, customizable, and highly interactive date picker component library. To get started, you can install it using npm or yarn with the following command:

1npm install react-datepicker --save
2# or
3yarn add react-datepicker

​

After installation, you can import the datepicker into your React app:

1import ReactDatePicker from 'react-datepicker';
2import 'react-datepicker/dist/react-datepicker.css';

​

Implementing Basic React Date Picker

To implement a basic react date picker, you need to set up the component and manage its state using React’s useState hook. Here’s an example of how to do it:

1import React, { useState } from "react";
2import ReactDatePicker from "react-datepicker";
3import "react-datepicker/dist/react-datepicker.css";
4
5export default function App() {
6  const [startDate, setStartDate] = useState(new Date());
7
8  return (
9    <ReactDatePicker
10      selected={startDate}
11      onChange={(date) => setStartDate(date)}
12    />
13  );
14}

​

In this example, useState is used to create a new date instance that will serve as the initial value or 'start date' for the date picker.

Customizing React DatePicker

React DatePicker allows for extensive customization to fit the design of your React app. You can add custom styling by passing a custom class name to the className prop or by directly styling the component using inline styles.

1<ReactDatePicker
2  selected={startDate}
3  onChange={date => setStartDate(date)}
4  className="custom-datepicker"
5  calendarClassName="custom-calendar"
6/>

​

You can also use the style prop to add inline styles:

1<ReactDatePicker
2  selected={startDate}
3  onChange={date => setStartDate(date)}
4  style={{ backgroundColor: 'lightblue' }}
5/>

​

Managing State with React DatePicker

Managing the state of the selected date is crucial for any date picker implementation. The useState hook is commonly used to track the selected date, and the onChange prop is used to update this state when the user picks a new date.

1const [selectedDate, setSelectedDate] = useState(new Date());
2
3const handleDateChange = date => {
4  setSelectedDate(date);
5};
6
7<ReactDatePicker
8  selected={selectedDate}
9  onChange={handleDateChange}
10/>

​

Advanced Features of React DatePicker

React DatePicker supports a variety of advanced features, such as selecting a date range, displaying week numbers, and integrating a time picker. To enable a date range selection and allow users to select a 'calendar date' within a specified range, you can use the startDate and endDate props:

1<ReactDatePicker
2  selected={startDate}
3  onChange={(date) => setStartDate(date)}
4  startDate={startDate}
5  endDate={endDate}
6  selectsRange
7/>

​

Additionally, React DatePicker enhances user experience by enabling users to 'display dates' in a calendar dialog format. For displaying week numbers, you can set the showWeekNumbers prop to true:

1<ReactDatePicker
2  selected={startDate}
3  onChange={(date) => setStartDate(date)}
4  showWeekNumbers
5/>

​

To include a time picker, you can use the showTimeSelect prop:

1<ReactDatePicker
2  selected={startDate}
3  onChange={(date) => setStartDate(date)}
4  showTimeSelect
5  timeFormat="HH:mm"
6  timeIntervals={15}
7  timeCaption="time"
8/>

​

Localization and Internationalization

React DatePicker supports localization to cater to different locales. You can import a locale object from the date-fns library and pass it to the locale prop:

1import { registerLocale, setDefaultLocale } from 'react-datepicker';
2import es from 'date-fns/locale/es'; // Spanish locale
3
4registerLocale('es', es);
5
6<ReactDatePicker
7  selected={startDate}
8  onChange={date => setStartDate(date)}
9  locale="es"
10/>

​

In this snippet, the registerLocale function is used to register the Spanish locale, and the locale prop is set to 'es' to localize the datepicker component.

Accessibility and Mobile Responsiveness

Ensuring that your date picker is accessible is key to providing a good user experience for all. React DatePicker comes with built-in accessibility features such as keyboard navigation and ARIA attributes. To further enhance mobile responsiveness, you can adjust the date picker's size and layout using CSS media queries or by utilizing the withPortal prop for a full-screen experience on mobile devices.

1<ReactDatePicker
2  selected={startDate}
3  onChange={date => setStartDate(date)}
4  withPortal
5/>

​

Date Fns Library: A Lightweight Alternative

The date-fns library is a lightweight alternative to other date manipulation libraries. It offers a modular approach, allowing you to import only the functions you need, which can significantly reduce your bundle size. Here's how you can use date-fns to format dates within your React date picker:

1import { format } from 'date-fns';
2
3const formattedDate = format(startDate, 'MMMM d, yyyy');

​

Creating a Custom Date Picker Component

For those who need a more tailored solution, creating a reusable datepicker component is the way to go. This approach allows you to encapsulate all the date picker logic and styling, making it easy to maintain and reuse across your application. Here's a basic structure of a custom date picker component:

1import React, { useState } from 'react';
2import ReactDatePicker from 'react-datepicker';
3
4const CustomDatePicker = ({ value, onChange }) => {
5  return (
6    <ReactDatePicker
7      selected={value}
8      onChange={onChange}
9      // Add any additional props and customization here
10    />
11  );
12};
13
14export default CustomDatePicker;

​

Handling Date Formats and Values

Working with dates in JavaScript can be tricky due to the various date formats. React DatePicker allows you to define the date format that you want to display and work with. You can set the dateFormat prop to any string format that you need, such as 'MM/dd/yyyy' or 'yyyy-MM-dd'.

1<ReactDatePicker
2  selected={startDate}
3  onChange={date => setStartDate(date)}
4  dateFormat="yyyy-MM-dd"
5/>

​

When it comes to handling the date value, React DatePicker provides a straightforward API. The onChange callback function receives the new date value whenever the user picks a date, allowing you to update the state or perform any other actions with the new date.

Integrating Date Picker with Forms

Integrating a React date picker with forms is a common use case. You can control the date picker's value via state and handle form submissions by accessing the date value from the state. Here's an example of how to integrate React DatePicker within a form:

1const [formData, setFormData] = useState({
2  date: new Date(),
3  // other form fields
4});
5
6const handleFormSubmit = event => {
7  event.preventDefault();
8  // Handle form submission using formData
9};
10
11<form onSubmit={handleFormSubmit}>
12  <ReactDatePicker
13    selected={formData.date}
14    onChange={date => setFormData({ ...formData, date })}
15  />
16  <button type="submit">Submit</button>
17</form>

Best Practices for Using Date Pickers

When using date pickers in React, it's important to follow best practices to ensure a smooth user experience. Some of these practices include:

• Providing clear labels and helper text for the date picker input field.

• Setting a reasonable default value that makes sense for the context of the form.

• Ensuring that the date picker is easily accessible and navigable using the keyboard.

Troubleshooting Common Issues

Developers may encounter issues such as incorrect date formats, localization problems, or styling conflicts. To troubleshoot these issues, check the full docs of the date picker library you're using, and ensure that you're passing the correct props and following the library's guidelines for customization and configuration.

Conclusion: Selecting the Best React Date Picker

In conclusion, the best react date picker for your application will depend on your specific requirements, such as the need for custom styling, advanced features, or localization support. By considering these factors and following best practices, you can implement an effective and user-friendly date picker in your React app.
