Getting started in EJ2 TypeScript Progressbar control

11 Nov 20235 minutes to read

This section explains the steps required to create the ProgressBar control using TypeScript and configure its properties 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 following list of dependencies are required to use the ProgressBar control in your application:

|-- @syncfusion/ej2-progressbar
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data: "*"
    |-- @syncfusion/ej2-svg-base

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

Add Progress Bar to the Application

Add an HTML div tag with its id attribute as element in your index.html file to initialize the ProgressBar control.

[src/index.html]

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

<head>
<title>Essential JS 2 ProgressBar</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>
<!--element which is going to render-->
<div id="element"></div>
</body>

</html>

Import the Progress Bar control to your app.ts file to instantiate a Progress Bar and append the instance to the #element as shown.

[src/app/app.ts]

app.ts
import { ProgressBar } from '@syncfusion/ej2-progressbar';

// Initialize ProgressBar component
let progressBar: ProgressBar = new ProgressBar({
      value: 40
});

// Render initialized ProgressBar
progressBar.appendTo('#element');

Run the application

Run the application in the browser using the following command.

npm start

Output will be as follows:

In the example, the #element is the id of the HTML element in a page to which the Progress Bar is initialized.

index.ts
index.html
import { ProgressBar } from '@syncfusion/ej2-progressbar';

    let percentageProgress: ProgressBar = new ProgressBar({
        type: 'Linear',
        height: '60',
        value: 40,
        animation: {
            enable: true,
            duration: 2000,
            delay: 0,
        },
    });
    percentageProgress.appendTo('#percentage');
