Implementing Syncfusion Vue Progressbar

The Syncfusion Vue Progressbar component displays the progress of a task to the user. It can be visualized in multiple shapes (linear, circular) and supports advanced features like animations, custom colors, annotations, and real-time event handling.

When to Use This Skill

Use the Progressbar component when you need to:

Display task progress (downloads, file uploads, form submissions)
Show real-time progress updates
Indicate multi-step processes with segmented progress
Display buffering or loading states
Combine progress with annotations (percentage text, images, buttons)
Track progress with custom ranges and multiple progress states
Provide accessibility-compliant progress indicators

Component Overview

Key Capabilities:

Multiple shape types: Linear, Circular
Progress states: Determinate (known progress), Indeterminate (unknown), Buffer (dual progress)
Customizable appearance: Colors, thickness, radius, segments
Annotations: Add custom content to circular progress bars
Labels: Display progress percentage or custom text
Tooltips: Show progress information on hover
Events: React to progress changes and completion
Accessibility: WCAG 2.2, Section 508, Screen reader support

Package: @syncfusion/ej2-vue-progressbar

Quick Start Example

<template>
  <div id="container">
    <ejs-progressbar
      id="percentage"
      type="Circular"
      :value="value"
      :animation="animation"
    >
    </ejs-progressbar>
  </div>
</template>

<script setup>
import { ProgressBarComponent as EjsProgressbar } from "@syncfusion/ej2-vue-progressbar";

const value = 100;
const animation = {
  enable: true,
  duration: 2000,
  delay: 0
};
</script>

<style>
#container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}
</style>

Common Patterns

1. Linear Progress with Animation

Use for sequential tasks or download progress
Set type="Linear" and configure animation duration
Display percentage label with showProgressValue

2. Circular Progress with Annotation

Use for circular task representation
Inject ProgressAnnotation service
Add custom content (percentage, icons, buttons) in center

3. Buffer/Secondary Progress

Use for buffering scenarios (video streaming)
Set secondaryProgress to show buffered amount
Combine with animation for smooth transitions

4. Segmented Progress

Use for multi-step processes
Set segmentCount to divide progress bar
Each segment represents a step

5. Indeterminate Progress

Use when progress amount is unknown
Set isIndeterminate="true"
Useful for loading states before actual progress data arrives

Key Props Reference

Prop	Type	Purpose
`value`	Number	Current progress value (0-100)
`type`	String	Shape: 'Linear', 'Circular'
`animation`	Object	Animation config (enable, duration, delay)
`isIndeterminate`	Boolean	Enable indeterminate mode
`secondaryProgress`	Number	Secondary progress value (0-100)
`segmentCount`	Number	Number of segments to divide progress
`showProgressValue`	Boolean	Display progress percentage/label
`minimum`	Number	Minimum value of range (default: 0)
`maximum`	Number	Maximum value of range (default: 100)
`progressColor`	String	Color of progress bar
`trackColor`	String	Color of track/background
`radius`	String	Radius for circular progressbars
`cornerRadius`	String	Corner style: 'Auro', 'Square', 'Round', 'Round4px'
`tooltip`	Object	Tooltip configuration (enable, format)

Common Use Cases

Use Case 1: File Upload Progress

Linear progressbar with animation
Update value prop as file uploads
Show percentage with showProgressValue

Use Case 2: Loading Indicator

Circular progressbar with indeterminate state
Use when waiting for API response
Transition to determinate once data arrives

Use Case 3: Multi-Step Form

Linear segmented progressbar
Update value as steps complete
Use segmentCount to show total steps

Use Case 4: Video Streaming

Linear progressbar with buffer (secondary progress)
Primary progress = video playback
Secondary progress = downloaded portion

Use Case 5: Task Completion Dashboard

Circular progressbar with annotation
Show percentage in center
Add completion button in annotation

Installation & Dependencies

npm install @syncfusion/ej2-vue-progressbar --save

Minimum Dependencies:

@syncfusion/ej2-base
@syncfusion/ej2-data
@syncfusion/ej2-svg-base

Next Steps

Choose your progressbar type: Linear or Circular
