3 Nov 20238 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 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.

Dependencies

The list of dependencies required to use the Calendar component in your application is given below:

|-- @syncfusion/ej2-calendars
  |-- @syncfusion/ej2-base
  |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-splitbuttons
  |-- @syncfusion/ej2-lists
  |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-buttons

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

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

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

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

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion CSS styles

To render Calendar component, need to import Calendar and its dependent components styles as given below in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-calendars/styles/material.css";

Add Calendar to the application

Add the HTML div tag with an ID attribute as the element to your index.html file.

[src/index.html]

<!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>

Then, import the Calendar component to your app.ts file, and initialize it with the #element
[src/app/app.ts].

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 by using the command below.

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');

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');
