Getting started in EJ2 TypeScript Calendar control

29 Jul 20268 minutes to read

This section explains how to create a simple Calendar, and configure its available functionalities in TypeScript, using Essential® JS 2 quickstart seed repository. This seed repository is pre-configured with the Essential® JS 2 package.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Prerequisites

Ensure the following tools are installed on your machine:

Set up the development environment

Clone the Syncfusion® TypeScript (Essential® JS 2) quickstart project from GitHub in the command prompt:

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack ej2-quickstart

Navigate to the project folder in the command prompt:

cd ej2-quickstart

Install Syncfusion® Calendar package

Syncfusion® TypeScript (Essential® JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion® TypeScript (Essential® JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

Use the following command to install the @syncfusion/ej2-calendars package:

npm install @syncfusion/ej2-calendars --save

Then, install the remaining dependent npm packages using the following command:

npm install

For more information about individual package and alternative installation methods, see the installation guide.

Import Syncfusion® Calendar CSS styles

Syncfusion® JavaScript controls provide built-in themes, which are available from the npm theme packages. Additionally, themes can be loaded via CDN or customized using the Theme Studio. For more information, refer to the themes documentation.

The quickstart application is preconfigured to use the Fluent2 theme. To install the Fluent2 theme package, use the following command:

npm install @syncfusion/ej2-fluent2-theme --save

The required styles are imported in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-fluent2-theme/styles/calendar/index.css";

Learn more about built-in themes and individual control CSS references.

Add Syncfusion® Calendar control to the application

The Calendar can be initialized through input tags.

Add the HTML input element which needs to be initialized as Calendar in index.html.

Open the application in Visual Studio Code and add the Syncfusion® TypeScript UI controls.

In this article, the Calendar control is used as an example. Add the following Calendar element to the ~/src/index.html file.

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 Calendar component</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
</head>

<body>
    <div style="margin: 50px;">
        <!--Element which is going to render the Calendar-->
        <div id="element"></div>
    </div>

</body>

</html>

Now, to render the Calendar control, add the following TypeScript code to the ~/src/app/app.ts file.

import { Calendar } from '@syncfusion/ej2-calendars';
//Initialize calendar component.
let calendarObject: Calendar = new Calendar();
//Render initialized calendar.
calendarObject.appendTo('#element');

Run the application

Now, run the application in the browser using the following command.

npm run start

The following example shows a basic Calendar component.

import { Calendar, ChangedEventArgs } from '@syncfusion/ej2-calendars';
// Creates a simple calendar component.
let calendarObject: Calendar = new Calendar();
calendarObject.appendTo('#element');
<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 Calendar control</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Typescript UI Controls" />
    <meta name="author" content="Syncfusion" />

    <!--style reference from app-->

    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    <script src="systemjs.config.js"></script>
</head>

<body>
    <div id='loader'>LOADING....</div>
    <div id='container'>
        <!--element which is going to render the Calendar-->
        <div id='element'></div>
    </div>
</body>

</html>

Setting the value, min and max dates

After rendering a simple Calendar component by following the above steps, configure the Calendar to set a value within a specific range using its value, min, and max properties.

Here the Calendar allows you to select a date within the range from 9th to 15th.

import { Calendar, ChangedEventArgs } from '@syncfusion/ej2-calendars';

let month: number = new Date().getMonth();
let fullYear: number = new Date().getFullYear();
// Creates a calendar with min max property.
let calendarObject: Calendar = new Calendar({
    // Sets the min.
    min: new Date(fullYear, month , 9),
    //Sets the max.
    max: new Date(fullYear, month, 15),
    // Sets the value.
    value: new Date(fullYear, month , 11)
});
calendarObject.appendTo('#element');
