Show Dynamic Statuses with the New Progress Bar in Essential JS 2

To add colorful animation effects to your progress indicator, you need a groundbreaking progress bar! In this aspect, our new Progress Bar control for the Essential JS 2 suite fulfills your need. This control is available with the 2020 Volume 1 release. It comes with the following functionalities:

• Determinate and indeterminate states
• Buffering
• Segmented progress
• Animation
• Custom content
• Right-to-left rendering
• Built-in themes
• Adaptability

The Progress Bar control can be used to visualize the changing status of an extended operation such as a download, file transfer, or installation. All progress bar elements are rendered using scalable vector graphics (SVG) to ensure the quality of the visual experience.

This blog will provide a walk-through on the Progress Bar control and its features.

Types

Progress Bar supports different shapes (rectangle, circle, and semi-circle) to give a unique design to the work progress visualization.

States

This feature allows you to visualize the changing status of an operation in different modes.

Determinate: Use this when the time of completion of a progression can be estimated.

Indeterminate: Use this when the time of completion of a progression can’t be estimated or calculated.

Buffer: Use this for co-related tasks.  It supports secondary progress, where the primary task depends on the secondary task.

Segments

This feature allows you to divide a progress bar into multiple segments to visualize the progress of multi-sequence tasks.

Angle

This feature allows you to customize the start and sweep angles of a circular progress bar to give a unique style to it.

Custom content

This feature allows you to add any custom content at the center of the circular progress bar to indicate the completion of progress or to add any custom text that conveys the current status of the progress.

Multiple ranges

This feature allows you to visualize the progress of a task with multiple color ranges.

Themes

Configure the look and feel of a progress bar using several built-in options to match with the application. The control supports the following themes:

• Fabric
• Material
• High contrast
• Bootstrap

Getting started with the Progress Bar in TypeScript

Let’s create a progress bar to give an attractive look to visualize measures. Follow these steps to configure the Progress Bar in TypeScript.

1. Clone the Essential JS 2 quick-start seed repository and configure the necessary packages in the config.js file.

   "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
    
   "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
    
   "@syncfusion/ej2- progressbar": "syncfusion:ej2-progressbar/dist/ej2-progressbar.umd.min.js",
   
   "@syncfusion/ej2-svg-base": "syncfusion:ej2-svg-base/dist/ej2-svg-base.umd.min.js"
   

2. Install the NPM packages using the following command.

   npm install
   

3. Add the HTML input element that needs to be initialized as a component in the index.html file.
4. Initialize the component in the ts file as shown in the following code.

   import { ProgressBar } from '@syncfusion/ej2-progressbar;
    
   // initialize progress bar component
   let linear: ProgressBar = new ProgressBar (
   {
    
        type: 'linear',
        value: 50, 
   }
   );
    
   // render initialized progress bar.
   linear.appendTo('#container');
   

5. You can change the value of the progress bar dynamically as shown in the following code.

   linear.value = 70;
   linear.dataBind();
