react-calender - Building a calender app in React JS

React Calender

In your react web app, managing and modifying dates is a common task. You may do things like add events or create reminders. You can do this by including a calendar in your web application.

In this article, we'll look at how to make calendars in ReactJS. This calendar can be used in your to-do list, e-commerce site, ticket booking site, and a variety of other apps.

What is react-calender

React-Calendar is a simple calendar library that allows you to select days, months, years, and even decades. For more complex use cases, it also supports date range selection and a variety of languages.

Because it is not dependent on moment.js, React-Calendar is a very flexible and versatile library that can be used in almost any application.

Feature of react-calender

  • Select from days, months, years, or even decades.

  • Allows for the selection of a range

  • It has the ability to support almost any language.

  • Not dependent on moment.js

  • JavaScript is needed.

Getting started with React Calender

Before implementing calender let us first create an project and install some dependencies.

Creating a react project

To create an react project enter following in command in your built-in terminal:

npm create-react-app react-calender-example

This may take a few minutes; wait for the development environment to be installed.

Installing react-calender in your react project

To add react calender in your react project run the following command:

npm install react-calender

Boiler Plate Code

// app.js import React,{useState} from 'react'; import Calendar from 'react-calendar'; const App = () => { const [date,setDate] = useState(new Date()); return ( <div> <div> <h1> Anoter Techs </h1> <h4> React Calendar </h4> </div> <div> <div> <Calendar onChange={setDate} value={date}/> </div> <div> Selected Date: {date.toString()} </div> </div> </div> ); }; export default App;

As in the above component you can see we have imported Calender component from react-calender. We have also created a state variable date which will hold today's date. We have passed this state to to value props of Calender component.

The onChange props of calender component take setDate function which will change the date whenever use click on certain date.

Styling react-calender

react-calender provides some default styling, which can be applied and used in react app. This file is located at node_modules/react-calendar/dist/Calendar.css and which can be imported as:

import "react-calendar/dist/Calendar.css"; import React,{useState} from 'react'; import Calendar from 'react-calendar'; import "react-calendar/dist/Calendar.css"; const App = () => { const [date,setDate] = useState(new Date()); return ( <div> <div> <h1> Anoter Techs </h1> <h4> React Calender </h4> </div> <div> <div> <Calendar onChange={setDate} value={date}/> </div> </div> </div> ); }; export default App;

Styling react-calender with custom CSS

React-custom Calendar's styles have a decent appearance. But we constantly aim for our parts to blend in with a product's overall design. React-elements Calendar's already have some classes that we can utilise to apply our styles.

The ideal method for implementing your styling is to override Calendar.css. This can be done by first copying the default Calendar.css into your working project. For example:

cp ./node_modules/react-calendar/dist/Calendar.css ./src/Calender.css

Here the destination path should be your desired path where you want to put the .css file. After this all you need to do is to import this custom Calender.css file in you app.

import React,{useState} from 'react'; import Calendar from 'react-calendar'; import "Calender.css"; ......

React Calendar Custom Style Example:

.react-calendar { width: 350px; max-width: 100%; background: #08baff; border: 1px solid #a0a096; border-radius: 15px; box-shadow: 5px 10px #795d70; font-family: Arial, Helvetica, sans-serif; line-height: 1.125em; } .react-calendar--doubleView { width: 700px; } .react-calendar--doubleView .react-calendar__viewContainer { display: flex; margin: -0.5em; } .react-calendar--doubleView .react-calendar__viewContainer > * { width: 50%; margin: 0.5em; } .react-calendar, .react-calendar *, .react-calendar *:before, .react-calendar *:after { -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; } .react-calendar button { margin: 0; border: 0; outline: none; } .react-calendar button:enabled:hover { cursor: pointer; } .react-calendar__navigation { display: flex; height: 44px; margin-bottom: 1em; } .react-calendar__navigation button { min-width: 44px; background: none; } .react-calendar__navigation button:disabled { background-color: #f0f0f0; } .react-calendar__navigation button:enabled:hover, .react-calendar__navigation button:enabled:focus { background-color: #e6e6e6; } .react-calendar__month-view__weekdays { text-align: center; text-transform: uppercase; font-weight: bold; font-size: 0.75em; } .react-calendar__month-view__weekdays__weekday { padding: 0.5em; } .react-calendar__month-view__weekNumbers .react-calendar__tile { display: flex; align-items: center; justify-content: center; font-size: 0.75em; font-weight: bold; } .react-calendar__month-view__days__day--weekend { color: #d10000; } .react-calendar__month-view__days__day--neighboringMonth { color: #5afff8; } .react-calendar__year-view .react-calendar__tile, .react-calendar__decade-view .react-calendar__tile, .react-calendar__century-view .react-calendar__tile { padding: 2em 0.5em; } .react-calendar__tile { max-width: 100%; padding: 10px 6.6667px; background: none; text-align: center; line-height: 16px; } .react-calendar__tile:disabled { background-color: #f0f0f0; } .react-calendar__tile:enabled:hover, .react-calendar__tile:enabled:focus { background-color: #5afff8; border-radius: 15px; } .react-calendar__tile--now { background: #ffff76; } .react-calendar__tile--now:enabled:hover, .react-calendar__tile--now:enabled:focus { border-radius: 15px; background: #ffffa9; } .react-calendar__tile--hasActive { background: #76baff; } .react-calendar__tile--hasActive:enabled:hover, .react-calendar__tile--hasActive:enabled:focus { background: #a9d4ff; border-radius: 15px; box-shadow: 5px 10px #795d70; } .react-calendar__tile--active { background: #795d70; border-radius: 50px; color: white; } .react-calendar__tile--active:enabled:hover, .react-calendar__tile--active:enabled:focus { background: #363129; } .react-calendar--selectRange .react-calendar__tile--hover { background-color: #e6e6e6; }

Date Range in react-calender

Date ranges are a feature of React-Calendar. Users can choose a specific date range as a result of this.

Then you can provide some information that is within the user's desired date range.

import React,{useState} from 'react'; import Calendar from 'react-calendar'; import './calendar.css'; const App = () => { const [dates,setDate] = useState([new Date(2022, 9, 1), new Date()]); return ( <div> <div> <h1> Anoter Techs </h1> <h4> React Calender </h4> </div> <div> <div> <Calendar onChange={setDate} selectRange={true} defaultValue={dates}/> </div> <div> <h4> Start Date: {dates[0].toDateString()} </h4> <h4> End Date: {dates[1].toDateString()} </h4> </div> </div> </div> ); }; export default App;

Date Range in React Calender
Date Range in React Calender

In the script above, we gave our Calendar component a selectRange parameter. The default setting for selectRange is false. This value was updated to true. The user can choose a date range thanks to this.

React calendar highlights the date range when a user selects a time frame to work with.

As our state, react-calendar then returns an array with two elements. The start date and the end date are indicated by the two elements. The array's start date and end date can then be printed.

React Calender Click Events

Numerous click event triggers are supported by React-Calendar. The most efficient props to support this are found in React-Calendar when you wish to trigger some function calls based on the user's action. The most popular events are listed below.

onChange

This is the most common type of props used in react-calender. This function is invoked when a user clicks on an item in the most detailed view.

onClickDay

When user clicks on a particular day in react calender component this function gets triggered. Similar to onClickDay, react calender also support onClickDecade, onClickMonth, onClickYead etc.

onViewChange

This function is invoked whenever the user switches between views by pressing the drill up button or clicking a tile.

Conclusion

We discussed adding the react-calendar package, customising it, setting a date range, and including a booking option in our react app.

Now that you know this information, you may use react to create a more dynamic and potent calendar.
